Description

Technical Field

[0001] This utility model relates to the field of fluid distribution technology, and in particular to a fluid distributor. Background Technology

[0002] In the field of decontamination of automated equipment (especially equipment with precision sensors such as cameras, lidar, proximity switches, etc.), it is often necessary to use fluids (such as compressed air, cleaning fluid, or mixed fluid) for purging or rinsing.

[0003] Specifically, during purging or flushing, a single pipeline is typically used to directly connect the fluid power source (such as an air pump or liquid pump) to the cleaning point. For multi-sensor devices, a separate pipeline is needed for each sensor to connect the fluid power source (such as an air pump or liquid pump) to the cleaning point, which is costly and involves complex wiring. Alternatively, a T-type or Y-type shunt can be used to split the fluid power source (such as an air pump or liquid pump) before using the split fluid medium to purge or flush the sensors. However, this method also has a limited number of output pipelines for splitting the fluid medium, making it difficult to meet the needs of widely distributed and numerous sensors. Utility Model Content

[0055] To address the problem of limited flow distribution lines when splitting the fluid medium output from a fluid power source in existing technologies, this utility model provides a fluid distributor.

[0056] Figure 1 This is a schematic diagram of the overall structure of the fluid distributor provided in this embodiment of the utility model. Figure 2 This is a cross-sectional view of the fluid distributor provided in an embodiment of this utility model. (In conjunction with...) Figures 1 to 2 This utility model provides a fluid distributor, comprising:

[0057] The system consists of an input terminal 1, a flow guide cavity 2, and an output terminal 3. The flow guide cavity 2 is located between the input terminal 1 and the output terminal 3. It can be understood that the flow guide cavity 2 is a cavity structure, and the input terminal 1 is connected to the output terminal 3 through the flow guide cavity 2.

[0058] Input terminal 1 is connected to an external fluid power source.

[0059] The fluid power source includes liquid pumps, air pumps, etc. Input terminal 1 can be connected to two or more fluid power sources. These two or more fluid power sources can be of the same type, such as all being liquid pumps, or they can be of different types, such as including both liquid pumps and air pumps. The fluid medium includes gaseous media, liquid media, and gas-liquid mixed-phase media. Among these, the gas-liquid mixed-phase media is a medium resulting from the mixing of a gaseous medium and a liquid medium.

[0060] A fluid power source inputs a fluid medium into the flow guide cavity 2 through input terminal 1. It can be understood that the flow guide cavity 2 is used to receive and temporarily store the fluid medium input from input terminal 1. Alternatively, if the fluid power source connected to input terminal 1 includes both a liquid pump and a gas pump, the flow guide cavity 2 is also used to mix the liquid phase medium output by the liquid pump and the gas phase medium output by the gas pump to obtain a gas-liquid mixed phase medium.

[0061] Among them, the flow guide cavity 2 also plays a role in initially stabilizing the fluid medium.

[0062] The output terminal 3 has multiple output holes 31 on its end face, wherein the number of multiple output holes 31 refers to two, three, or more output holes 31. Preferably, the multiple output holes 31 are three or more output holes 31. Specifically, the number of output holes 31 is determined according to the size of the output holes 31 and the end face size of the output terminal 3, or the number of output holes 31 is set according to requirements.

[0063] The fluid power source inputs a fluid medium into the guide cavity 2 through the input terminal 1. After flowing through the guide cavity 2, the fluid medium is output to the outside through multiple output holes 31. That is, the fluid medium output by the fluid power source enters or is temporarily stored in the guide cavity 2 through the input terminal 1 and is output through multiple output holes 31. The output fluid medium is used to clean the surface (or spot) to be cleaned on external automated equipment (especially equipment with precision sensors such as cameras, lidar, proximity switches, etc.).

[0064] Optionally, multiple output holes 31 are respectively connected to external fluid lines. It is understood that one output hole 31 is connected to one fluid line, which is used to spray fluid medium toward the surface (or spot) to be cleaned on the automated equipment (especially the equipment with precision sensors such as cameras, lidar, proximity switches, etc.) to clean the surface (or spot) to be cleaned on the automated equipment.

[0065] When multiple output ports 31 are connected to external fluid lines, standard pipe fittings can be used to connect the output ports 31 to the external fluid lines. These standard pipe fittings can be plug fittings, compression fittings, or threaded fittings. A sealing element (or sealing component) can also be installed between the output ports 31 and the external fluid lines to ensure a tight seal between the output ports 31 and the external fluid lines. This sealing element can be an O-ring or a gasket.

[0066] In this embodiment, multiple output holes are provided at the output end, which serve as diversion holes for the fluid medium. The number of diversion holes can be set according to requirements, thereby increasing the number of output pipelines for the fluid medium output by the fluid power source and achieving flexible configuration.

[0067] The fluid distributor provided in this embodiment can replace multiple independent fluid medium output pipelines, simplifying the piping and installation of fluid cleaning systems for automated equipment.

[0068] In some embodiments, to ensure the fluid distributor's sealing performance and increase its service life, the input end 1, the guide cavity 2, and the output end 3 are manufactured using a one-piece molding process. That is, it can be understood that the fluid distributor is manufactured using a one-piece molding process, and the fluid distributor is a single, integral structure, with the input end 1, the guide cavity 2, and the output end 3 each being a part of the fluid distributor.

[0069] The fluid distributor is made using a one-piece molding process, which eliminates the connection point between the input end 1, the guide cavity 2 and the output end 3, and further eliminates the risk of leakage between the input end 1, the guide cavity 2 and the output end 3.

[0070] In some embodiments, the input end 1 and the guide cavity 2 are manufactured using a one-piece molding process, and the output end 3 is also manufactured using a one-piece molding process. That is, after the input end 1 and the guide cavity 2 are manufactured using a one-piece molding process, and the output end 3 is manufactured using a one-piece molding process, the output end 3 and the guide cavity 2 are combined to obtain the fluid distributor. In this embodiment, the fluid distributor adopts a modular design, which facilitates the production and manufacturing of the fluid distributor. The combination of the output end 3 and the guide cavity 2 refers to the fixed and sealed connection between the output end 3 and the guide cavity 2.

[0071] By adopting a modular design, the damaged part can be replaced individually after it is damaged, which facilitates processing and subsequent maintenance.

[0072] The fixed and sealed connection between the output end 3 and the guide cavity 2 can be achieved by one of the following methods: 1), 2), 3), and 4):

[0073] Method 1) Welding method. By welding the output end 3 to the guide cavity 2, the interface between the output end 3 and the guide cavity 2 can be made tighter and the sealing performance can be better.

[0074] In this method 1), the output end 3 and the flow guiding cavity 2 can be made of metal materials, that is, the output end 3 and the flow guiding cavity 2 can be welded by metal welding; the output end 3 and the flow guiding cavity 2 can be made of plastic materials, that is, the output end 3 and the flow guiding cavity 2 can be welded by plastic welding.

[0075] Method 2) Bolted Connection. Threaded holes can be made in both the portion of the flow guide cavity 2 facing the output end 3 and the portion of the output end 3 facing the flow guide cavity 2. These threaded holes are then connected by bolts, securing the flow guide cavity 2 and the output end 3 in a sealed connection. Of the threaded holes in the flow guide cavity 2 and the output end 3, one is a through hole and the other is a blind hole. Alternatively, threads can be provided on the outer surface of the flow guide cavity 2, and a matching thread can be provided on the inner wall of the output end 3 (i.e., the output end 3 is considered a bolt). The flow guide cavity 2 and the output end 3 are then secured by a threaded connection. Alternatively, threads can be provided on the inner wall of the flow guide cavity 2 (i.e., the flow guide cavity 2 is considered a bolt), and a matching thread can be provided on the outer surface of the output end 3. The flow guide cavity 2 and the output end 3 are then secured by a threaded connection.

[0076] In this method 2), a sealing ring is provided at the output end 3 and the guide cavity 2 to ensure the sealing between the output end 3 and the guide cavity 2.

[0077] Method 3) Snap-fit ​​connection. A snap-fit ​​block can be set on the flow guide cavity 2 and a snap-fit ​​groove can be set on the output end 3. The snap-fit ​​block and the snap-fit ​​groove are connected to achieve the snap-fit ​​connection between the flow guide cavity 2 and the output end 3, that is, the fixed and sealed connection between the flow guide cavity 2 and the output end 3. Alternatively, a snap-fit ​​groove can be set on the flow guide cavity 2 and a snap-fit ​​block can be set on the output end 3. The snap-fit ​​block and the snap-fit ​​groove are connected to achieve the snap-fit ​​connection between the flow guide cavity 2 and the output end 3, that is, the fixed and sealed connection between the flow guide cavity 2 and the output end 3. Alternatively, a quick-connector base can be provided on the flow guide cavity 2, and a quick-connector female head can be provided on the output end 3. The flow guide cavity 2 and the output end 3 can be snapped together by inserting the quick-connector female head into the quick-connector base, that is, a fixed and sealed connection between the flow guide cavity 2 and the output end 3. Or, a quick-connector female head can be provided on the flow guide cavity 2, and a quick-connector base can be provided on the output end 3. The flow guide cavity 2 and the output end 3 can be snapped together by inserting the quick-connector female head into the quick-connector base, that is, a fixed and sealed connection between the flow guide cavity 2 and the output end 3.

[0078] In this method 3), a sealing ring is provided at the output end 3 and the guide cavity 2 to ensure the sealing between the output end 3 and the guide cavity 2.

[0079] Method 4) Rotary locking connection. A male buckle can be set on the flow guide cavity 2 and a female buckle can be set on the output end 3. The flow guide cavity 2 and the output end 3 are connected by inserting the male buckle into the female buckle and rotating it, that is, a fixed and sealed connection between the flow guide cavity 2 and the output end 3. Alternatively, a female buckle can be set on the flow guide cavity 2 and a male buckle can be set on the output end 3. The flow guide cavity 2 and the output end 3 are connected by inserting the male buckle into the female buckle and rotating it, that is, a fixed and sealed connection between the flow guide cavity 2 and the output end 3.

[0080] In this method 4), a sealing ring is provided at the output end 3 and the guide cavity 2 to ensure the sealing between the output end 3 and the guide cavity 2.

[0081] Method 5) Clamp connection method. After aligning the flow guide cavity 2 and the output end 3, clamps are used to clamp the outer surface of the flow guide cavity 2 and the outer surface of the output end 3 to achieve the connection between the flow guide cavity 2 and the output end 3, that is, the fixed and sealed connection between the flow guide cavity 2 and the output end 3.

[0082] In this method 5), a sealing ring is provided at the output end 3 and the guide cavity 2 to ensure the sealing between the output end 3 and the guide cavity 2.

[0083] The rotary locking connection and clamp connection are fastening methods that use a quick-clamping mechanism, which can accelerate the installation and disassembly process. When using the rotary locking connection and clamp connection to connect the guide cavity 2 and the output end 3, it is necessary to ensure that there is sufficient clamping force between the guide cavity 2 and the output end 3 to ensure a seal between them.

[0084] Optionally, limiting structures such as limiting holes, limiting posts, limiting blocks, and limiting grooves can be provided on the flow guiding cavity 2. Limiting structures such as limiting holes adapted to the limiting posts, limiting posts adapted to the limiting holes, limiting blocks adapted to the limiting grooves, and limiting grooves adapted to the limiting blocks can be provided on the output end 3. After limiting the flow guiding cavity 2 and the output end 3, the flow guiding cavity 2 and the output end 3 are fixedly connected using the above method. The design of the limiting structures allows for rapid positioning of the flow guiding cavity 2 and the output end 3, facilitating subsequent fixed connection.

[0085] The following details the specific methods for setting sealing rings at the output end 3 and the guide cavity 2 in methods 2), 3), 4), and 5) above:

[0086] A first groove is formed on the end face of the flow guiding cavity 2 facing the output end 3, and a second groove is formed on the end face of the output end 3 facing the flow guiding cavity 2. The first and second grooves are used to accommodate the sealing ring. When the sealing ring is placed in the annular groove between the flow guiding cavity 2 and the output end 3, the sealing ring is compressed when the flow guiding cavity 2 and the output end 3 are fixedly connected, thereby increasing the sealing performance between the flow guiding cavity 2 and the output end 3.

[0087] It is understandable that the sealing ring has a ring-shaped structure, such as an O-ring. In this case, the first groove is an annular groove, and the second groove is also an annular groove. The sealing ring can also be a non-circular gasket. In this case, the first and second grooves are also shaped to fit the non-circular gasket.

[0088] The following describes in detail the setting methods of the aperture (or orifice diameter) of the multiple output holes 31 in this embodiment, including the following methods one, two, and three:

[0089] Method 1: In this method, the diameter (or aperture) of each of the multiple output holes 31 is equal. In this method, the specific value of the diameter (or aperture) of the multiple output holes 31 can be determined based on the pressure of the fluid medium output from the output hole 31 and the distance between the second end of the fluid output pipeline and the surface to be cleaned on the automated equipment that needs to be cleaned.

[0090] Method 2: Among the multiple output holes 31, the diameter (or orifice diameter) of each output hole 31 is not equal; that is, the diameter (or orifice diameter) of any two output holes 31 is not equal. In this Method 2, the specific value of the diameter (or orifice diameter) of each output hole 31 can be determined based on the pressure of the fluid medium output from the output hole 31 and the distance between the output hole 31 and the surface to be cleaned on the automated equipment that needs to be cleaned.

[0091] Method 3: Multiple output holes 31 include N groups of output holes 31, each group of output holes 31 includes at least one output hole 31, and the diameter (or aperture) of each group of output holes 31 is equal, and the diameters (or apertures) of the output holes 31 in different groups are not equal, where N is a positive integer greater than 2. That is, in this Method 3, multiple output holes 31 are divided into multiple groups of output holes 31, each group of output holes 31 includes at least one output hole 31, and the diameters (or apertures) of each group of output holes 31 are designed to be equal, but the diameters (or apertures) of the output holes 31 in different groups are not equal, so that the multiple output holes 31 include both output holes 31 with equal diameters (or apertures) and output holes 31 with unequal diameters (or apertures).

[0092] In this method three, the specific value of the aperture (or orifice diameter) of each set of output holes 31 can be determined based on the pressure of the fluid medium output from the output hole 31 and the distance between the output hole 31 and the surface (or spot) to be cleaned on the automated equipment that needs to be cleaned.

[0093] It should be noted that different automated devices may require different fluid media for decontamination due to differences in location, type of stain, or sensitivity. For example, high-pressure blowing may be used to remove dust, while low-flow precision rinsing may be required. For instance, remotely located automated devices may need a small-diameter output orifice 31 to increase the output pressure of the fluid medium, while locally located automated devices may need a large-diameter output orifice 31 to increase the output flow rate and reduce output resistance. Any of the methods described in Method 1, Method 2, and Method 3 can be used to differentiate the orifice diameter of the output orifice 31 to ensure that the pressure or flow rate of the fluid medium output from the output orifice 31 meets the decontamination requirements of the surface (or stain) on the automated device. Furthermore, the orifice diameter of the output orifice 31 can be designed using any of the methods described in Method 1, Method 2, and Method 3 based on the decontamination requirements of the surface (or stain) on the automated device, achieving precise distribution of fluid medium flow rate or pressure.

[0094] Furthermore, regarding the above method three, there are two specific implementation methods:

[0095] Specific Implementation Method 1: When the end face of output terminal 3 is circular, the end face of output terminal 3 is divided into N-1 annular regions and one circular region. The N-1 annular regions and the circular region share a common center, which is the center of the end face of output terminal 3. That is, the end face of output terminal 3 is divided from the center outwards into a circular region and N-1 annular regions. Preferably, the radius of the circular region is equal to the diameter of each annular region.

[0096] In this embodiment, a set of output holes 31 is provided in an annular region and a set of output holes 31 is provided in a circular region. That is, in this specific embodiment, the diameter of the output holes 31 provided in different annular regions is different, or the diameter of the output holes 31 provided in the annular region and the circular region is different, but the diameter of the output holes 31 provided in one annular region or one circular region is the same.

[0097] Specific implementation method 2: When the end face of the output terminal 3 is circular, the end face of the output terminal 3 is divided into N sector regions. Preferably, the central angles of each sector region are equal.

[0098] In this embodiment, a set of output holes 31 is provided in one sector-shaped region. That is, in this second embodiment, the diameter of the output holes 31 provided in different sector-shaped regions is different, but the diameter of the output holes 31 provided in one sector-shaped region is the same.

[0099] Figure 3 This is one of the structural schematic diagrams of the fluid output terminal provided in this embodiment. Figure 4This is the second schematic diagram of the fluid output terminal provided in this embodiment, as shown below. Figure 3 and Figure 4 As shown, an output hole 31 extends from the end face of the output terminal 3 in a direction away from the input terminal 1, meaning that the output hole 31 protrudes from the end face of the output terminal 3. This design facilitates cleaning and maintenance of the output hole 31.

[0100] In another alternative, the output port 31 is a pipe opened inside the output end 3, that is, the output end 3 is a solid structure, and multiple output ports 31 are opened inside the solid structure. This design can save the design space of the fluid distributor and simplify the design of the fluid distributor.

[0101] To meet actual needs, in an optional embodiment, multiple holes are opened on the end face of the output terminal 3, and the output hole 31 is connected to the holes.

[0102] The number of holes is the same as the number of output holes 31, and one output hole 31 is connected to one hole.

[0103] In this optional embodiment, the output hole 31 is mounted on the end face of the output end 3. This optional embodiment allows the output end 3 to be fitted with output holes 31 of different sizes. Specifically, when different sizes of output holes 31 are required, it is not necessary to change the hole size on the output end 3. It is only necessary to assemble output holes 31 of different sizes on the output end 3. That is, the mold of the output end 3 does not need to be changed, thus saving process steps.

[0104] In this optional embodiment, to ensure the sealing of the connection, the size of the outer surface of the output hole 31 is equal to the size of the connection surface of the hole. Furthermore, the connection between the output hole 31 and the hole includes at least one of the following methods: 6), 7), and 8).

[0105] Method 6) Welding method. Welding the output hole 31 to the hole can make the interface between the output hole 31 and the hole tighter and the sealing better.

[0106] Preferably, ultrasonic welding can be used.

[0107] Method 7) Bolt connection. Threads can be made on the outer surface of the output hole 31, and matching threads can be made on the connecting surface of the hole. The output hole 31 and the hole can be fixedly and sealed by threaded connection.

[0108] This method allows for quick replacement of output port 31.

[0109] 8) Rotary locking connection method. A male buckle can be set on the output hole 31 and a female buckle can be set on the connecting surface of the hole. The output hole 31 is connected to the hole by inserting the male buckle into the female buckle and rotating it. Alternatively, a female buckle can be set on the output hole 31 and a male buckle can be set on the connecting surface of the hole. The output hole 31 is connected to the hole by inserting the male buckle into the female buckle and rotating it.

[0110] This method allows for quick replacement of output port 31.

[0111] It should be noted that if the fluid medium directly impacts the wall of the output terminal 3, it will cause a significant loss of the fluid medium's dynamics. In order to reduce the dynamic loss of the fluid medium, in some embodiments, the end face of the output terminal 3 is designed with one of the following structures:

[0112] Structure 1: The end face of output terminal 3 is an arc surface structure (or a spherical structure).

[0113] Optionally, the arc-shaped structure (or spherical structure) protrudes toward the input end 1 or toward a direction away from the input end 1. Preferably, in order to facilitate the extension of the output hole 31 on the end face of the output end 3, the arc-shaped structure (or spherical structure) protrudes toward a direction away from the input end 1.

[0114] Structure 2: The end face of output terminal 3 is a wavy curved surface structure.

[0115] Optionally, in order to facilitate the extension of the output hole 31 on the end face of the output end 3, the output hole 31 is provided on the protruding end of the wavy curved surface structure that protrudes away from the input end 1.

[0116] Structure 3: The end face of output terminal 3 is a sawtooth-shaped end face structure.

[0117] Optionally, in order to facilitate the extension of the output hole 31 on the end face of the output end 3, the output hole 31 is provided on the protruding end of the sawtooth end face structure that protrudes away from the input end 1.

[0118] Optionally, the cross-sectional shape of the output hole 31 can be circular, rectangular, funnel-shaped, I-shaped, Y-shaped, etc.

[0119] In some embodiments, such as Figure 1 and Figure 2 As shown, the diameter of the flow guiding cavity 2 gradually increases from the input end 1 to the output end 3. That is, the smaller diameter end of the flow guiding cavity 2 is connected to the input end 1, and the larger diameter end of the flow guiding cavity 2 is connected to the output end 3. This design can increase the number of output holes 31 set at the output end 3, facilitate the arrangement of a flow distribution structure in the flow guiding cavity 2 to distribute the fluid medium in the flow guiding cavity 2, and also stabilize the dynamics of the fluid medium stored in the flow guiding cavity 2.

[0120] In some embodiments, a flow-diverting structure is provided inside the flow-guiding cavity 2. The function of the flow-diverting structure is to divert the fluid medium inside the flow-guiding cavity 2 to ensure the stability of the fluid medium output from the flow-guiding cavity 2.

[0121] In one optional embodiment, the flow splitting structure includes multiple flow splitting plates, and a flow splitting channel for the fluid medium is formed between any two adjacent flow splitting plates. After the fluid medium enters the flow guiding cavity 2, it is split through the flow splitting channel and then exits the flow guiding cavity 2.

[0122] Preferably, the dimensions of the flow distribution channels formed between any two adjacent flow distribution plates are as equal as possible to ensure uniform flow distribution of the fluid medium.

[0123] In this optional implementation, multiple flow dividers can be connected to form a fixed integrated structure. In this case, the two flow dividers at the edges can be fixed in the flow guide cavity 2 to achieve the installation of multiple flow dividers.

[0124] In another alternative embodiment, the diversion structure includes multiple diversion pipes. After the fluid medium enters the diversion cavity 2, it is diverted through the diversion pipes and then output from the diversion cavity 2.

[0125] Preferably, the diameters of the multiple branch pipes are the same to ensure uniform distribution of the fluid medium. The specific value of the diameter of the branch pipe can be determined according to the size of the guide cavity 2; that is, the larger the size of the guide cavity 2, the larger the diameter of the branch pipe.

[0126] In some embodiments, the fluid distributor further includes a flow distribution mechanism configured to regulate the fluid on / off state via at least one output port 31, i.e., in this embodiment, the flow distribution mechanism opens (or releases) or closes (or blocks) the output port 31.

[0127] Specifically, the flow distribution mechanism includes at least one of the following structures: Structure 4, Structure 5, and Structure 6:

[0128] Structure 4: Plug head 4. The plug head 4 is detachably connected to the output port 31 and is used to close or open the output port 31.

[0129] Optionally, the sealing head 4 is detachably connected to the output port 31, such as... Figure 5 As shown, the sealing head 4 is arranged according to... Figure 5 Move in the direction indicated by the middle arrow to close the output port 31. The plugging head blocks the output port 31, preventing it from outputting fluid medium. The plugging head 4 moves in accordance with... Figure 5 Move in the opposite direction indicated by the middle arrow to open the output port 31. The plug head releases the output port 31, allowing the output port 31 to output fluid medium.

[0130] The plugging head 4 and the output hole 31 can be detachably connected by having threads on the outside of the plugging head and matching threads on the inner surface of the output hole 31.

[0131] Structure 5: Selector Valve. The selector valve is configured to selectively block one or more output orifices 31.

[0132] Optionally, the selector valve can be installed in the output port 31. For example, a selector valve can be installed in one output port 31 and the selector valve can be connected to a control device (or controller). The selector valve is controlled by the control device and can selectively block one or more output ports 31, or the selector valve is controlled by the control device and can selectively open one or more output ports 31.

[0133] Structure Six: Valve Plate 5; The valve plate is movably disposed between the flow guiding cavity 2 and multiple output holes 31. The valve plate 5 has through holes; by changing the position of the valve plate 5, the through holes can be aligned or misaligned with different output holes 31 to selectively open or close the corresponding output holes 31. A schematic diagram of the valve plate 5 is shown below. Figure 6 As shown.

[0134] In this structure six, the flow distribution mechanism also includes a drive structure 6, which is connected to the valve plate 5. The position of the valve plate 5 is changed by the drive structure 6, so that the through hole is aligned or misaligned with different output holes 31.

[0135] Optionally, the drive structure 6 can be a drive rod. The drive structure 6 drives the valve plate 5 to move, so that the through hole is misaligned with different output holes 31, thereby closing (or blocking) the output hole 31 and preventing the output hole 31 from outputting fluid medium. The drive structure 6 drives the valve plate 5 to move, so that the through hole is aligned with different output holes 31, thereby opening (or releasing) the output hole 31 and allowing the output hole 31 to output fluid medium.

[0136] like Figure 5 As shown, when the drive structure 6 is located at the solid line position in the figure, the through hole is misaligned with different output holes 31; when the drive structure 6 is located at the dashed line position in the figure, the through hole is aligned with different output holes 31.

[0137] Optionally, the size of the through hole on the valve plate 5 is equal to the diameter of the output hole 31, and the number of valve plates 5 is equal to the number of output holes 31. One valve plate 5 opens or closes one output hole 31.

[0138] Optionally, the drive structure 6 can also drive the valve plate 5 to open or close the output port 31 by rotating or sliding, and multiple drive structures can be designed to control different output ports 31 to open or close respectively. The drive structure can also be an external knob or adjustment tool.

[0139] By designing a drive structure to control the opening or closing of different sealing holes, it is possible to individually control the closing of certain output holes 31 that need to be closed or the opening of certain output holes 31 that need to be opened, so as to control the output of fluid medium from some output holes 31 and improve the control flexibility and versatility of the fluid distributor.

[0140] This design allows the output port 31 to be opened or closed according to actual needs, enabling the fluid distributor provided in this embodiment to be adapted to the surfaces (or spots) to be cleaned in different automated equipment, reducing the types of spare parts. It also allows for dynamic adjustment of the opening and closing of the output port 31, such as temporarily closing a certain output port 31 when maintenance is required.

[0141] It should be noted that the valve plate 5 can be made of metal, plastic or rubber materials, and the specific material of the valve plate 5 can be determined according to the properties of the fluid medium.

[0142] In another implementation, the fluid distributor further includes a solenoid valve disposed within the output port 31, which is used to close or open the output port 31.

[0143] It is understandable that a solenoid valve is installed inside an output port 31, and the opening and closing of the output port 31 are controlled by energizing and de-energizing the solenoid valve.

[0144] This design allows the output ports 31 to be opened or closed according to actual needs. It enables individual control of certain output ports 31 that need to be closed to close or certain output ports 31 that need to be opened to open, thereby controlling the output of fluid medium from some output ports 31 and improving the flexibility and versatility of the fluid distributor.

[0146] Optionally, to facilitate the setting of the flow control valve, the flow control valve is a miniature flow control valve, such as a needle valve or a ball valve, so as to avoid affecting the flow of the fluid medium in the output port 31.

[0147] In this embodiment, the flow regulating valve is used to adjust the flow rate of the fluid medium in the output port 31 and the fluid medium output from the output port 31, in order to adapt to more complex decontamination requirements.

[0148] A flow regulating valve can also be designed at the first end of part of the output port 31, or at the second end of part of the output port 31, or inside part of the output port 31.

[0149] In some embodiments, the fluid distributor further includes a pressure sensor, which is disposed at the first end of the output port 31, or at the second end of the output port 31, or inside the output port 31, or inside the flow guiding cavity 2. Optionally, an interface can be reserved at the above-mentioned locations for installing the pressure sensor. The pressure sensor is used to detect the pressure of the fluid medium, facilitating the monitoring and adjustment of the fluid medium pressure. The first end and the second end of the output port 31 are the two opposite ends of the output port 31.

[0150] The pressure sensor can be a pressure gauge.

[0151] Preferably, a pressure sensor is provided at the first end of each output port 31, or at the second end of each output port 31, or in each output port 31, so as to realize real-time monitoring of the pressure of the fluid medium in each output port 31.

[0152] In some embodiments, the fluid distributor further includes a flow sensor disposed at the first end of the output port 31, or at the second end of the output port 31, or inside the output port 31, or inside the flow guide cavity 2. The flow sensor is used to detect the flow rate of the fluid medium, so as to facilitate monitoring and adjustment of the flow rate of the fluid medium.

[0153] Preferably, a flow sensor is provided at the first end of each output hole 31, or at the second end of each output hole 31, or in each output hole 31, so as to realize real-time monitoring of the flow rate of the fluid medium in each output hole 31.

[0154] In some embodiments, the input terminal 1 is made of rubber, metal, or plastic, and the output terminal 3 is made of rubber, metal, or plastic.

Plastic materials are made from polypropylene (PP), polyethylene, polyvinylidene fluoride (PVDF), and polyetheretherketone (PEEK). Plastic materials offer advantages such as high-temperature resistance and resistance to corrosion.

[0156] It should be noted that the specific materials used to make input terminal 1 and output terminal 3 can be determined based on the properties of the fluid medium.

[0157] Preferably, the input terminal 1 and the output terminal 3 are made of the same material.

[0158] In some embodiments, a mounting bracket 7 is provided on the side of the fluid distributor for mounting the fluid distributor to other structures or devices.

[0159] Optionally, the mounting bracket 7 is made using a one-piece molding process, which facilitates the stable installation of the fluid distributor or ensures the stability of the fluid distributor in a vibration environment.

[0160] In some embodiments, a fluid distribution structure is provided in the flow guiding cavity 2, and multiple interconnected fluid distribution paths are opened in the fluid distribution structure. The first end of the fluid distribution path is connected to the input end 1, and the second end of the fluid distribution path is connected to the output end 3. The multiple interconnected fluid distribution paths are used to distribute the fluid medium in the flow guiding cavity 2 to adapt to the cleaning of the surface (or spot) to be cleaned on automated equipment of different distances or types.

[0161] Alternatively, multiple interconnected fluid distribution pathways can be formed into a tree structure, a star structure, or a ring channel network structure.

[0162] In some embodiments, the output port 31 is connected to another fluid distributor, which can serve as a sub-stage miniature fluid distributor following the fluid distributor provided in this embodiment, to adapt to multi-channel requirements. It is understood that the flow rate or pressure of the fluid medium output by the sub-stage miniature fluid distributor is lower than the flow rate or pressure of the fluid medium output by the fluid distributor provided in this embodiment.

It can flexibly configure the number of output branches according to needs, accurately match the fluid power requirements of different sensors through differentiated output orifice diameters, ensure reliable sealing of each connection point and split joint surface to prevent leakage, and facilitate installation and maintenance.
