Description

Technical Field

[0001] This application relates to the field of pneumatic pipeline logistics transmission, and more specifically, to a specimen sorting and sending device. Background Technology

[0002] Existing technologies also disclose multi-pipeline path switching devices for specimen classification and transmission, such as...

[0003] CN114604581A discloses a rotary multi-channel specimen delivery mechanism. The rotary multi-channel specimen delivery device consists of a multi-channel rotating body and a device housing. The multi-channel rotating body is designed with multiple specimen storage channels, which are designed with the same radius and equal angles around the multi-channel rotating body. The multi-channel rotating body is designed with an output port cover and an input port cover on two sides corresponding to the device housing. The output port cover has a pipe interface on its plane. The specimen storage channels on the multi-channel rotating body are sealed between the two ends and the cover.

[0004] The shortcomings of the above solution are as follows: 1. The above solution only distributes and transports specimens. However, specimens have different sizes. After the system is connected to the testing equipment, the size of the specimens needs to be adjusted, and automatic connection cannot be achieved; 2. The transfer device in the above solution requires the input port, specimen storage tube hole and output port to be completely aligned before the specimen can be transported. The output efficiency is low. Moreover, compressed air is used for transportation. Therefore, the two ends of the rotating body and the two ends of the shell need to be designed with sealing structures. The sealing structures are complex and have high manufacturing costs. Summary of the Invention

[0005] The main objective of this application is to provide a specimen sorting and delivery device to solve the problems of the inability to automatically sort specimens by size and the low delivery efficiency.

[0006] To achieve the above objectives, a specimen sorting and delivery device is provided.

The frame is also provided with an eccentric wheel, which is driven to rotate by a reduction motor. The movable column transmission frame and the eccentric wheel are connected by a linkage rod.

[0014] A further improvement is that the scanning mechanism includes a scanning roller rotatably mounted on the frame, the scanning roller having a roller groove that mates with the specimen, a scanner being mounted above the scanning roller, and the scanning roller being driven to rotate by a stepper motor.

[0015] A further improvement is that the specimen delivery module includes a module housing, a left cover plate and a right cover plate fixedly disposed at both ends of the module housing, and a piston body slidably disposed within the module housing. Both the left cover plate and the right cover plate are provided with compressed air inlets. The piston body is provided with piston tube holes along the vertical direction. The upper left pipe opening and the specimen inlet are sequentially provided on the upper part of the module housing. The lower part of the module housing is provided with a lower pipe opening. The upper left pipe opening corresponds to the lower pipe opening. A guide structure is also provided between the piston body and the module housing.

[0018] A further improvement is that the drive mechanism includes a servo motor fixedly mounted on the first housing cover plate, a drive wheel fixedly connected to the motor shaft of the servo motor, and a rotating plate driven wheel fixedly mounted on the first rotating plate.

[0019] Compared with the prior art, the specimen sorting and sending device provided by the present invention has the following advantages: 1. The present invention adopts a combined structure method of sorting first and then transmitting, which is a fundamental breakthrough compared with the conventional method of sending first and then sorting. It can reduce the investment of a sorting device for the laboratory, and directly transmit the specimen to the port of each laboratory device without the need for manual participation in the transmission process. The level of automation and transmission efficiency are improved, and the test report can be delivered to the doctor in advance, shortening the diagnosis and treatment time. This further expands the application of the device and qualitatively changes the transmission effect.

[0020] 2. The present invention uses a barcode scanning roller structure in the sorting stage of the device, which not only increases the time of the specimen scanning process and makes the barcode reading more stable and accurate, but also isolates the control of the specimen entering the sending channel, effectively avoiding the problem that two specimens may enter the sending channel at the same time. By utilizing the characteristics of the roller, the purpose of recovering undecoded specimens is achieved. The structure is simple and the function is prominent.

[0021] 3. This invention adds specimen size identification to the propulsion mechanism of the sending channel, which serves as a front-end support for specimen classification and direct delivery to the machine. To achieve this, the bottom of the specimen chute in the propulsion mechanism is designed as a double arc shape, so that the small end of the specimen entering the chute can be accurately centered for identification. The front end of the contact in the top rod is designed as a hollow structure without a bottom plate, which ensures that the contact can successfully insert the small end of the specimen every time, making the design of identifying specimen size possible. Solving the problem without adding unnecessary structures in the process is conducive to stable operation.

[0022] 4. This invention uses a combined structure for multi-pipe specimen delivery. The specimen exits the station upwards from the device. The directional wheel design at this position replaces the 90-degree rotation of the specimen into the delivery device, which also fulfills the design requirement of the specimen exiting the machine with the small end facing upwards. At the same time, it allows for a more reasonable arrangement of the emergency specimen delivery at the preferred port. The specimen inlet and outlet of the directional wheel adopts a large open design to facilitate the entry of the push rod and to ensure that the specimen accurately enters the delivery module.

[0023] 5. The specimen delivery module of this invention requires no driver; it only needs compressed air input to achieve two-position switching, completing the function of safely ejecting the specimen from an unpressurized state to a pressurized zone. The module uses a dual-guide rod positioning system to position the piston in the cylinder and adjust the piston stroke on the end cap of the housing, ensuring precise alignment between the piston tube hole of the delivery module and the transmission pipe hole on the housing. Once set, no cumulative deviation will occur. A three-inlet, two-outlet cylinder structure design can also be selected as needed, making the device more powerful and meeting the operational needs of large hospitals during peak hours.

[0024] 6. The multi-pipe transfer mechanism of the present invention is a fully enclosed, high-speed, and precise positioning pipe path transfer device, precisely controlled by a servo motor. This device is linked to the sending module mechanism and is designed in combination in the space above the sending device or in the ceiling. A single pipe enters the multi-pipe transfer mechanism, and multiple pipes are installed in the ceiling. The reasonable device structure makes installation simpler and more aesthetically pleasing, and control more convenient. The multi-pipe installation method can also be changed to multiple directions according to the environment and needs. Moreover, it does not require a lot of planar sealing structures, the structure is relatively simple, and the processing cost is reduced. Attached Figure Description

[0044] like Figures 1 to 2 As shown in the figure, a specimen sorting and dispensing device includes: a specimen storage bin 10, a sorting mechanism, a scanning mechanism, a pushing mechanism, a direction adjustment mechanism, a specimen dispensing module, and a multi-pipeline path transfer device, all connected in sequence. The specimen storage bin 10 is where the specimens are stored. It is located at the front of the device and has a specimen inlet 101 on its side. Upon entering, the specimen first falls onto the specimen bin bottom plate 103 between the first-stage moving column 331 and the first-stage fixed column 341 of the sorting mechanism 30. The first-stage fixed column 341, second-stage fixed column 342, and third-stage fixed column 343 are fixed to the structure of the device housing 11. A specimen baffle 344 separates the specimen storage bin 10 from the mechanism, preventing the specimens from directly entering the second layer position of the moving column 33 of the sorting mechanism 30. The specimen storage chamber 10 in the device housing 11 is designed with a specimen chamber cover 102 and a cover handle 106. The LCD panel 107 is the interface for operating the device. The system transmission pipe 28 and the transmission port 56 are designed on the device panel.

[0045] like Figures 1 to 2 As shown in the figure, the regulating mechanism 30 is composed of multiple levels of fixed columns 34 and movable columns 33 stacked alternately. The fixed columns 34 are positioned and installed on the box body. The movable columns 33 are composed of a movable column transmission frame 36, a first-level transmission reinforcing plate 361, and a second-level transmission reinforcing plate 362 as a whole. The upper surface width of the fixed columns 34 and the movable columns 33 is larger than the length of a specimen, and the thickness is less than or equal to the maximum diameter of the specimen. The design is to prevent two specimens from being placed on the columns at the same time. When each movable column 33 is raised to the highest position, its upper surface is higher than the upper surface of the fixed column. The design of the upper surface of the column being higher on the outside and lower on the inside is to facilitate the specimen rolling to the next level.

[0046] like Figure 3As shown, the moving column 33 of the regularization mechanism 30 synchronously performs lifting and lowering movements in both directions. The lifting and lowering drive of the moving column 33 is controlled by the reduction motor 31. The reduction motor 31 is fixed to the structure of the housing 11 through the motor base 310. One end of the eccentric wheel 32 is fixed to the shaft of the reduction motor 31, and the other end is fixed to the connecting rod 37. The other end of the connecting rod 37 is fixed to the connecting rod shaft 370, and the other end of the connecting rod shaft 370 is fixed to the moving column transmission frame 36. The moving column transmission frame 36 and the three-stage moving column 33 are fixed as one unit.

[0047] like Figures 1 to 2 As shown, the scanning roller 35 has a roller groove 351 on its outer circumference, which is the specimen carrier surface. A layer of adhesive film 354 is attached around the outer circumference of the scanning roller 35 to increase the friction of the specimen on the scanning roller 35. The roller groove 351 is designed with a large R-curve on both sides to facilitate the specimen rolling out in advance during retrieval. The large arc cover designed on the outer circumference of the scanning roller 35 can control the specimen from going out of bounds.

[0048] like Figure 2 As shown, the barcode scanner 38 is mounted at an angle above the barcode scanning roller 35 via the barcode scanner bracket 381. The barcode scanning roller 35 is fixed to the structure of the housing 11 via the roller bracket 350. A driven wheel is mounted on the shaft of the barcode scanning roller 35. The barcode scanning roller 35 is driven to rotate by a stepper motor driven by the roller driver 353. The driver wheel 352 mounted on the shaft of the roller driver 353 is a synchronous wheel, which is connected to the driven wheel on the shaft of the barcode scanning roller 35 by a synchronous belt.

[0049] like Figures 2 to 5 As shown, the specimen slide 43 on the propulsion mechanism 40 is fixed directly below the barcode scanning roller 35.

The push rod contact 421 is the specimen push rod of the push rod 42, and the contact faces the direction wheel 50. A drive shaft 411 is designed on the side of the push rod 42, and a magnet 47 is installed on the top. The long arm fork of the push arm 48 is positioned in the drive shaft 411. The lower section of the push rod is designed with a lever fulcrum 481 fixed to the structure. The lever drive point 482 is installed on the cylinder rod. The drive cylinder 41 is fixed to the structure. The specimen contact 421 is positioned in the specimen slide 43 by the long arm of the push arm 48 under the drive of the drive cylinder 41, and performs two actions: pushing and retracting. Position sensors 3# 45 and 4# 46 are fixed at the two working magnet 47 positions of the push rod 42 for pushing and retracting. The infrared sensor 44 is fixed in the rear hole of the push rod 42. The infrared sensor emitter is visible in the center hole of the hollow circle without a bottom plate of the specimen contact 421.

[0050] like Figures 1 to 2As shown, the central axis of the directional wheel 50 is fixed by the wheel shaft mounting bracket 55 on the center line between the center of the specimen slide 43 of the propulsion mechanism 40 and the center line of the specimen inlet 220 of the specimen sending module. When the wheel tube hole of the directional wheel 50 is horizontal, the wheel 1# port 51 is aligned with the direction of the specimen slide 43. When the wheel tube hole of the directional wheel 50 is vertical, the wheel 1# port 51 is aligned with the center line of the transmission port 56. The wheel driver 53 is installed to the right of the directional wheel 50 and drives the wheel driven wheel 501 on the shaft of the directional wheel 50 to rotate through the synchronous belt 541 of the wheel drive wheel 531.

[0051] The port 56 is designed on the device panel. A port baffle 58 and a detection sensor 54 for specimen detection are installed in the middle section of the port 56's pipe. One end of the port baffle 58 is fixed to the shaft of the baffle driver 57. See [link / reference]. Figure 1 The recovery slide 591 is installed on the lower left outer circle of the barcode scanning roller 35. The recovered specimen slides into the recovery chamber 59 from the lower left through the recovery slide 591.

[0052] like Figures 6 to 9 As shown, the rotating body 61 in the pipeline path conversion device 60 is composed of a first rotating plate 613, a second rotating plate 614, and a conversion pipe 63. The zero port 631 of the conversion pipe 63 is inserted into the inner port of the input port 620 of the first rotating plate 613, and the outlet port of the conversion pipe 63 is inserted into the inner port of the output port 632 of the second rotating plate 614. They are fixed as a whole by the rotating body support rod 615 and the outer cover 616 of the rotating body.

[0053] The rotating plate passive wheel 611 and the pipe column 612 are designed at the center of the outer plane of the first rotating plate 613. The inner edge of the center hole of the pipe column 612 is designed with the installation position of the sealing ring 65 and the spring washer 651. The outer periphery of the pipe column 612 is the positioning shaft of the first rotating plate 613 of the rotating body 61, which is tightly fitted with the positioning bearing 64 on the first housing cover plate 627. The second rotating plate 614.

Then, the pipe column of the first rotating plate 613 of the rotating body 61 is inserted into the inner pipe port 620 of the input pipe port 620 of the first housing cover plate 627. The timing belt is installed, and the first housing cover plate 627 is inserted into the adapter housing 62 and fixed tightly with bolts through the cover plate mounting hole 6280.

[0055] See Figures 1 to 2 As shown: The specimen sending module 20 consists of a piston body 21 and a mechanism housing 22. All the sealing rings 27 are installed in position on the piston body 21, and the magnetic rings 219 are installed in position. The piston body 21 is then placed into the mechanism housing 22.

[0056] The right cover plate 225 is used to fix two right guide shafts 216 and the No. 2 compressed air inlet 242. The left cover plate 226 is used to fix two left guide shafts 215 and the No. 1 compressed air inlet 241. The left cover plate 226 is then placed on top. The two left guide shafts 215 on the left cover plate 226 are aligned with the guide holes 210 on the piston body 21 and inserted. The cover plate bolts 2261 are then tightened. The two left guide shafts 216 on the right cover plate 225 are aligned with the guide holes 210 on the piston body 21 and inserted. The cover plate bolts 2261 are then tightened. Install position sensor 261 and position sensor 262 in the outer groove of the housing 22 of the mechanism to the correct positions, and then debug the position accuracy of the pipe hole of the specimen sending module 20 to ensure that the piston hole 212 of the piston body 21 is accurately aligned with the center of the specimen inlet 220 when the piston body 21 is in position 1, and ensure that the piston hole 212 of the piston body 21 is accurately aligned with the center of the upper left pipe opening 222 when the piston body 21 is in position 2.

[0057] See Figures 1 to 2 As shown: The specimen delivery module 20 is installed on the device body. The striking port 2241 of the lower pipe port 224 is connected to the compressed air pipe via a solenoid valve. The system transmission pipe 28 is connected to the upper left pipe port 222 of the specimen delivery module 20.

[0058] In this embodiment of the invention, the regularization mechanism 30 is composed of multiple levels of fixed columns 34 and movable columns 33 stacked alternately. The fixed columns 34 are positioned and installed on the box body, and the movable columns 33 are composed of connecting rods and transmission rods as a whole. The width of the upper surface of the fixed columns and movable columns is greater than the length of a specimen, and the thickness is less than or equal to the maximum diameter of the specimen. The upper surface of the columns is designed to be higher on the outside and lower on the inside.

[0059] In this embodiment of the invention, the regulating mechanism is composed of multiple levels of fixed columns and movable columns stacked alternately. The fixed columns are positioned and installed on the device body. The movable columns are composed of a movable column transmission frame 36, a first-level transmission reinforcing plate 361, and a second-level transmission reinforcing plate 362 combined into a whole. The upper surface width of the fixed column 34 and the movable column 33 is greater than the length of a specimen, and the thickness is less than or equal to the maximum diameter of the specimen. The upper surface of the column is designed to be higher on the outside and lower on the inside.

[0060] In this embodiment of the invention, the movable column 33 of the regularization mechanism 30 simultaneously performs lifting and lowering movements in both directions. When each movable column 33 is raised to its highest position, its upper surface is higher than the upper surface of the fixed column 34.

[0061] The scanning roller 35 described in this embodiment of the invention has a length greater than that of a specimen, and has a roller groove 351 on its outer circumference. The inner width and height of the roller groove 351 are greater than the outer diameter of the specimen. A layer of roller adhesive 354 is attached to the outer circumference of the scanning roller 35. The two sides of the groove are designed with a large R-curve. The outer circumference of the scanning roller 35 is designed with a roller arc cover 355.

[0062] In this embodiment of the invention, when the scanning roller 35 rotates clockwise, the rotation direction of the specimen is the same as the rolling direction when it comes down from the moving column 33 of the regularization mechanism 30. When the scanning roller 35 rotates counterclockwise, the specimen immediately detaches from the scanning roller and enters the recovery slide 591. The scanning roller 35 rotates 180 degrees clockwise for the specimen decoding process. After decoding, it continues to rotate 180 degrees clockwise and then the specimen enters the sending channel. If decoding fails, the scanning roller rotates counterclockwise to recover the specimen. Regardless of whether the scanning roller rotates clockwise or counterclockwise, the large roller arc cover 355 outside the scanning roller 35 can guide the specimen's direction. The scanning roller 35 needs to rotate 360 ​​degrees to complete one decoding process and needs to rotate 180 degrees to recover one specimen.

[0063] In this embodiment of the invention, the propulsion mechanism 40 includes a specimen slide 43, a propulsion arm 48, and a propulsion push rod 42. The propulsion push rod 42 is mounted on a guide rail 410. A drive shaft 411 is designed on the side of the propulsion push rod 42. The long arm fork of the propulsion arm 48 is positioned in the drive shaft 411. The lower section of the propulsion arm 48 is designed with a lever fulcrum 481. The lever drive point 482 is mounted on a cylinder rod. The drive cylinder 41 is fixed to the machine body. The push rod contact 421 is positioned in the specimen slide 43 by the propulsion arm 48 under the drive of the cylinder to perform two actions: propulsion and retraction.

[0064] In this embodiment of the invention, the push rod contact 421 is designed in the specimen slide groove 43 of the push rod 42, and the push rod contact 421 faces the reversing wheel.

[0065] In this embodiment of the invention, the specimen groove 43 is designed with a structure of two circular arc radii at the bottom, with a small semi-circular arc at the bottom and a large semi-circular arc at the top. The large end of the specimen cannot enter the groove of the small arc, and the small end of the specimen is centered in the groove of the small arc.

[0066] In this embodiment of the invention, the top rod contact 421 is designed as a hollow circle without a bottom plate. The front end of the top rod contact 421 is an open opening in the shape of an outward V. The inner diameter of the top rod contact 421 is larger than the outer diameter of the small end of the specimen and smaller than the outer diameter of the large end of the specimen.

[0067] In this embodiment of the invention, the detection element installed in the center of the rear part of the push rod contact 421 is a reflective infrared sensor 44.

[0068] In this embodiment of the invention, the directional wheel 50 is a flat circular shape with a wheel tube hole 501 designed in the center. The length of the wheel tube hole 501 is equal to the diameter of the directional wheel 50. The diameter of the directional wheel 50 is greater than the longest specimen length, and the diameter of the wheel tube hole 501 is greater than the maximum diameter of the specimen.

[0069] In this embodiment of the invention, the drive shaft of the directional wheel 50 is fixed at the center of the two side planes. The specimen entrance of the wheel 1# port 51 is open. A passive wheel is installed at one end of the drive shaft of the directional wheel 50 and is driven by a geared motor via a synchronous belt to rotate in two directions.

[0070] In this embodiment of the invention, when the directional wheel 50 is in standby mode, the pipe port 51 of the wheel 1# is aligned with the specimen slide port 43 of the propulsion mechanism. The specimens in the direction of the specimen slide port 43 and the superior transmission port 56 of the propulsion mechanism 40 enter through the wheel 1# port 51 of the directional wheel 50. The directional wheel 50 is driven by a stepper motor via a synchronous belt to rotate 90 degrees in only two directions.

[0071] In this embodiment of the invention, the directional wheel 50 is used for directional positioning of the specimen before it enters the specimen sending module 20. When the specimen enters the directional wheel 50 from the regularization mechanism 30, if the small end of the specimen enters first, the directional wheel 50 rotates 90 degrees clockwise. If the large end of the specimen enters first, the directional wheel 50 rotates 90 degrees counterclockwise. The specimen with the large end facing down falls into the specimen sending module 20 first. The specimen enters from the preferred port 56 only if the large end enters first.

[0072] The specimen sending module driver of this invention does not require a driver.

The device rotating body 61 is formed by a conversion pipe 63 to form a specimen passage path.

[0074] In this embodiment of the invention, the connecting pipe 63 in the rotating body 61 of the device has an S-shaped shape. Both ends of the pipe are embedded in the outer grooves of the circular holes of the first rotating plate 613 and the second rotating plate 614 of the rotating body.

[0077] Device operation process description:

[0078] The specimen is sent from the blood collection window to the sorting and sending equipment via the synchronous belt of the blood collection table. The specimen enters the specimen storage chamber 10 from the equipment inlet 101. The sorting mechanism 30 lifts specimen A from the specimen storage chamber 10 one by one from the specimen storage chamber 10 to the scanning roller 35 via the moving columns 33. When the specimen is lifted onto the three-stage moving columns 333, the infrared light of the barcode scanner 38 is triggered and turned on. At this time, the scanning roller 35 starts to start. The roller groove 351 of the scanning roller 35 rotates clockwise upward with the roller groove facing downward. The specimen rotates counterclockwise under the action of the roller mold 354 of the scanning roller 35. The specimen falls into the roller groove 351 of the scanning roller 35, and the decoding process ends. After successful decoding, the roller driver 353 continues clockwise by 180 degrees to transfer the specimen to the specimen chute 43 of the propulsion mechanism 40. If decoding fails, the roller driver 353 rotates counterclockwise by 90 degrees to discard the specimen onto the recovery chute 591, and the roller groove 351 returns to its downward position. The second specimen waiting on the third-stage moving column 333 will only be delayed and started after the roller groove 351 stops rotating downwards, and the clockwise rotation will execute the reading and decoding operation for the second specimen. If there is no specimen on the third-stage moving column 333 during the specimen decoding process, the moving column 33 can continue to work normally until a specimen is available on the third-stage moving column 333. The moving column 33 can stop working at any height. This process repeats. The specimen enters the propulsion mechanism 40, the drive cylinder 41 of the push rod 42 is activated, the #3 magnetic sensor 45 is disconnected, and the sensor 44 inside the push rod contact 421 detects reflected information, proving that the small end of the specimen is facing backward. If there is no signal return, it proves that the large end of the specimen is facing backward. The propulsion arm 48 of the propulsion mechanism 40 drives the push rod 42 to push the specimen from the #1 port 51 of the rotating wheel 50 into the rotating tube hole 501 of the rotating wheel 50. The #4 magnetic sensor 46 is activated, the propulsion arm 48 of the propulsion mechanism 40 is immediately retracted, and the #4 magnetic sensor... When device 46 is disconnected, magnetic sensor 45 #3 is turned on after reaching the standby position (the propulsion mechanism completes one specimen propulsion). The stepper motor of the rotary wheel driver 53 starts. If the specimen is small-end, it enters first from rotary wheel #1 port 51, rotates 90 degrees clockwise and stops. The specimen large-end enters specimen inlet 220 of specimen sending module 20 first. If the specimen large-end enters rotary wheel #1 port 51, it rotates 90 degrees counterclockwise and stops. The specimen slides out from rotary wheel #2 port, and the large-end still enters specimen inlet 220 of specimen sending module 20 first.The rotor #1 is the only entry point for the specimen. After the specimen enters through the specimen delivery module 20, compressed air enters through the compressed air inlet 242. The piston tube hole 212 of the piston body 21 moves towards the upper left port 222. When the magnetic sensor #1 is off and the magnetic sensor #2 is on, the piston tube hole 212 of the piston body 21 aligns with the upper left port 222. Compressed air instantly enters the lower pipe port 224, and the specimen is ejected upwards from the upper left port 222. The specimen instantly enters the pipe path conversion device 60 in the ceiling. Previously, the system had pre-rotated the outlet 632 of the rotating body 61 in the mechanism to the corresponding output outlet 621-626. When the specimen passed through this transmission outlet, the sensor on the transfer pipe 63 detected the passage information, and the solenoid valve of the compressed air inlet 68 on the corresponding output outlet was instantly opened. At the same time, the solenoid valve of the lower pipe outlet 224 of the linked specimen sending module 20 was instantly closed. The specimen was driven by the positive pressure of the compressed air entering through the compressed air inlet 68 of the pipe path transfer device 60 to move rapidly towards the target point. Upon reaching the target point, the smaller end of the specimen first enters the matrix anchor head, and the classification and transmission of one specimen is completed.

[0079] The solenoid valve at the lower pipe port 224 in the specimen sending module 20 is instantaneously linked with the solenoid valve at the compressed air inlet 68 of the output pipe of the pipeline path conversion device 60. When the output pipe port of the rotating body 61 of the pipeline path conversion device 60 is positioned at the No. 1 output pipe port 621, the solenoid valve at the lower pipe port 224 is linked with the solenoid valve at the No. 1 output pipe port 621. The solenoid valve at the No. 1 output pipe port 621 closes the instant the solenoid valve at the lower pipe port 224 opens, and vice versa.
