The capacity value of the first solution contained in the first solution transferring groove 416 of the first solution transferring structure 410 is larger than the capacity value of the second solution contained in the second solution transferring groove 426 of the second solution transferring structure 420, so that the solution proportioning and mixing requirements can be met.

At the same time, the other first liquid transferring groove 416 on the first liquid transferring frame 414 rotates to a position corresponding to the first outlet 104 and the first liquid inlet 4122, so that the first solution in the first container 100 is injected into the corresponding first liquid transferring groove 416 again with the first volume, and during the rotation of the first liquid transferring frame 414, the first solution with the first volume in the first liquid transferring groove 416 can be discharged into the third container 300 again, and thus the cycle is performed.

Similarly, in the initial state, the second liquid inlet 4222 on the second pipetting shell 424 is correspondingly communicated with the second outlet 204 of the second container 200 and one second liquid pipetting groove 426 of the second pipetting frame 424, so that the second container 200 naturally injects the second solution with the second capacity into one second liquid pipetting groove 426 of the second pipetting frame 424 through the second outlet 204 and the second liquid inlet 4222, and the second pipetting frame 424 rotates under the action of the gravity of the second solution in the second liquid pipetting groove, so that the second liquid pipetting groove 426 and the second solution therein rotate to the second liquid outlet 4224 at the bottom of the second pipetting shell 424, and the second solution with the second capacity in the second liquid pipetting groove 426 is naturally discharged from the second liquid outlet 4224 to the third container 300 through the second inlet 306.

When the first solution naturally flows into one of the first pipetting grooves 416 of the first pipetting wheel 4144 on the top of the first pipetting frame 414, the first pipetting wheel 4144 rotates under the gravity of the first solution in the first pipetting groove 416 with the first volume, so that the first pipetting groove 416 on the top of the first pipetting wheel 4144 rotates to the bottom position and is drained. Further, the second pipetting frame 424 may include a second pipetting wheel 4244 provided on the second pipetting shaft 4242, and the plurality of second pipetting grooves 416 are provided on a circumferential side of the second pipetting wheel 4244 in the circumferential direction. Similarly, when the second solution naturally flows into one of the second pipetting grooves 426 of the second pipetting wheel 4244 of the second pipetting frame 424, which is located at the top, the second pipetting wheel 4244 rotates under the gravity of the second solution in the second pipetting groove 426 with the second capacity, so that the second pipetting groove 426 located at the top of the second pipetting wheel 4244 rotates to the bottom position and is drained.

Still further, the pipetting wheel may include a wheel sleeve sleeved on the pipetting shaft, one wheel end plate disposed at each of two ends of the wheel sleeve, and a plurality of wheel partitions disposed along a circumferential direction of the wheel sleeve and extending radially of the wheel sleeve, where two sides of each wheel partition are correspondingly connected to the two wheel end plates, and the plurality of pipetting grooves are respectively disposed between the plurality of wheel partitions and the two wheel end plates.

Moreover, the second pipetting wheel 4244 may include a second wheel sleeve sleeved on the second pipetting shaft 4242, one second wheel end plate 42444 disposed at each of two ends of the second wheel sleeve, and a plurality of second wheel partitions 42444 disposed along a circumferential direction of the second wheel sleeve and extending radially of the second wheel sleeve, wherein two sides of each second wheel partition 42444 are correspondingly connected to two second wheel end plates 42442, and the plurality of second pipetting grooves 426 are respectively disposed between the plurality of second wheel partitions 42444 and the two second wheel end plates 42442.

Moreover, in the present embodiment, the pipetting axis of the first pipetting structure 410 (i.e., the first pipetting axis 4142) is coaxially arranged with the pipetting axis of the second pipetting structure 420 (i.e., the second pipetting axis 4242). The first pipetting shaft 4142 of the first pipetting frame 414 and the second pipetting shaft 4242 of the second pipetting frame 424 may be set to be the same shaft, and the first pipetting frame 414 and the second pipetting frame 424 may rotate together with the first pipetting shaft 4142 (or the second pipetting shaft 4242), so that the first pipetting frame 414 and the second pipetting frame 424 may rotate synchronously. In this way, the first pipetting channel 416 of the first pipetting structure 410 and the second pipetting channel 426 of the second pipetting structure 420 can be brought to receive the first solution in the first container 100 and the second solution in the second container 200, respectively, and simultaneously rotate and transport them into the third container 300. Moreover, the first pipetting shaft 4142 and the second pipetting shaft 4242 may be coaxially disposed, so that the first pipetting structure 410 and the second pipetting structure 420 have better rotation synchronism and more stable rotation.

In addition, the first pipetting shaft 4142 of the first pipetting frame 414 and the second pipetting shaft 4242 of the second pipetting frame 424 may be separately and independently provided so that the first pipetting frame 414 and the second pipetting frame 424 are each independently rotated.

In addition, in the present embodiment, the first pipetting shell 412 of the first pipetting structure 410 may be integrally disposed with the second pipetting shell 424 of the second pipetting structure 420, that is, the first pipetting structure 410 and the second pipetting structure 420 may be integrally disposed, which is more compact. Furthermore, a first runner end plate 41442 of the first pipetting frame 414 may be provided on a second runner end plate 42442 of the second pipetting frame 424, i.e. the first pipetting frame 414 and the second pipetting frame 424 may be further provided as a unit, and may be rotated synchronously.

In addition, the first pipetting shell 412 and the second pipetting shell 422 may be provided separately, and the first pipetting frame 414 and the second pipetting frame 424 may be provided separately, as needed.

In addition, a first damping structure can be arranged between the pipetting rotating shaft and the pipetting shell. Through setting up first damping structure between pipetting pivot and pipetting shell, can increase the resistance between the two for the two can take place relative rotation only needing overcoming the resistance of this first damping structure. Therefore, when the solution with enough capacity (such as the first capacity or the second capacity) is injected into the liquid moving groove at the top of the liquid moving frame, the liquid moving frame overcomes the resistance of the first damping structure under the action of the gravity of the solution and can rotate along with the liquid moving rotating shaft. Specifically, one first damping structure may be disposed between the first pipetting spindle 4142 and the first pipetting shell 412 and another first damping structure may be disposed between the second pipetting spindle 4242 and the second pipetting shell 422; in addition, when the pipetting axes of the first pipetting structure 410 and the second pipetting structure 420 are arranged coaxially, one first damping structure may be arranged only between the first pipetting axis 4142 and the first pipetting shell 412 or between the second pipetting axis 4242 and the second pipetting shell 422.

In addition, a second damping structure can be arranged between the pipetting wheel and the pipetting shell. Similarly, by arranging the second damping structure between the pipetting wheel and the pipetting shell, the resistance between the pipetting wheel and the pipetting shell can be increased, so that the pipetting wheel and the pipetting shell can rotate relatively only by overcoming the resistance of the second damping structure. Similarly, a second damping structure may be disposed between the first pipetting shaft 4142 and the first pipetting shell 412 and another second damping structure may be disposed between the second pipetting shaft 4242 and the second pipetting shell 422; in addition, when the pipetting axes of the first pipetting structure 410 and the second pipetting structure 420 are coaxially arranged, a second damping structure may be provided only between the first pipetting axis 4142 and the first pipetting shell 412 or between the second pipetting axis 4242 and the second pipetting shell 422.

In addition, it should be noted that at least one of the first damping structure and the second damping structure may be provided.

Moreover, the friction disc structure may include a first friction block provided on an inner circumferential surface of the pipetting shell, or/and a second friction block provided on an outer circumferential surface of the pipetting wheel; alternatively, the friction disc structure may comprise a third friction block provided on the inner end surface of the pipetting shell, or/and a fourth friction block provided on the outer end surface of the pipetting wheel.

In addition, the structure of the first damping structure may be the same as or similar to the structure of the second damping structure.

In addition, as shown in fig. 2 to 5, the pipetting mechanism 400 may include a locking and blocking device 430 provided on the third container 300, where the locking and blocking device 430 is correspondingly matched with each of the first pipetting structure 410 and the second pipetting structure 420 to prevent the solution in the first pipetting structure 410 and the second pipetting structure 420 from being drained. When the volume of the third solution (mixed by the first solution and the second solution) in the third container 300 reaches the preset value, the pipetting operations of the first pipetting structure 410 and the second pipetting structure 420 can be stopped by the locking and blocking device 430, and the solution in the first container 100 and the solution in the second container 200 are not transferred to the third container 300.

Specifically, the locking and blocking device 420 may include a floating spoiler that is floatingly disposed in the third liquid chamber 302 of the third container 200, and the floating spoiler may be correspondingly engaged with the pipetting frame of the first pipetting structure 410 and the pipetting frame of the second pipetting structure 420 at the same time. The floating spoilers of the locking spoilers 430 can float upward as the solution in the third container 300 increases such that the floating spoilers can approach and limit the pipetting frame of the first pipetting structure 410 and the pipetting frame of the second pipetting structure 420 to prevent them from rotating pipetting. In addition, the locking and blocking device 420 may be configured as a locking structure or a latch structure, so as to limit the pipetting frame of the first pipetting structure 410 (the first pipetting frame 414) and the pipetting frame of the second pipetting structure 420 (the second pipetting frame 424).

Further, the floating spoilers may include a floating block 432 floating in the third liquid chamber 302 of the third container 300, and a limiting plate 434 connected to the floating block 432, and the limiting plate 434 may protrude out of the third container 300 and be correspondingly engaged with the pipetting axes of the first pipetting structure 410 and the second pipetting structure 420 at the same time. When the solution level in the third container 300 is low, the limiting plate 434 is in a separated state from the pipetting spindle; when the solution level in the third container 300 reaches the preset level, the limiting plate 434 is raised along with the rise of the floating body block 432, so that the limiting plate 434 is clamped with the pipetting spindle, thereby limiting the rotation of the pipetting spindle (at this time, the pipetting rack rotates along with the pipetting spindle), and stopping the rotation of the pipetting rack. In addition, the limiting plate 434 of the floating spoiler can be correspondingly matched with the pipetting wheel of the pipetting frame, so that the rotation of the pipetting wheel can be directly limited.

Furthermore, a limit slot may be disposed at the top of the limit plate 434, and the limit slot may be correspondingly matched with the pipetting spindle (the first pipetting spindle 4142 or/and the second pipetting spindle 4242). When the limiting plate 434 is lifted to the position of the pipetting rotating shaft, the pipetting rotating shaft can be limited by the limiting clamping groove of the limiting plate 434. In addition, a stop lever (or a stop pin) may be disposed at the top of the stop plate 434, and a corresponding stop hole may be disposed on the pipetting shaft, so that when the stop plate 434 rises to the position of the pipetting shaft, the stop lever may penetrate into the stop hole to stop the pipetting shaft.

Moreover, the pipetting rotating shaft can comprise a main rotating shaft connected with the pipetting rotating wheel and a special-shaped shaft section arranged on the main rotating shaft, and the limiting clamping groove is correspondingly matched with the special-shaped shaft section. The special-shaped shaft section can be arranged on the pipetting rotating shaft, and the limiting clamping groove on the limiting plate 434 can be set to be a corresponding special-shaped clamping groove, so that the special-shaped shaft section can be more conveniently limited through the special-shaped clamping groove, and the pipetting rotating shaft is limited to stop rotating. For example, the profiled shaft section may be provided as a rectangular or semi-circular shaft, or as a shaft body of other irregular shape.

In addition, the top of the third container 300 may further be provided with a limiting cylinder 301 having a limiting cavity in a protruding manner, the limiting plate 434 of the floating spoiler may extend from the inside of the limiting cavity of the limiting cylinder 301 to protrude outside thereof, and a gap communicating with the third liquid chamber 302 may be provided between the circumferential side of the limiting plate 434 and the inner wall of the limiting cavity, and the gap may be in communication with the atmosphere. By providing the limiting cylinder 301 on the third container 300, not only the limiting plate 434 of the floating spoiler can be guided and limited to avoid inaccurate limitation caused by the deviation in the process of floating and limiting the displacement of the liquid frame, but also the air in the third container 300 can be discharged through the gap in the limiting cylinder 301 so as to be easily discharged into the third container 300.

Moreover, the cross-sectional area of the floating body pieces 432 of the floating spoilers may be greater than the cross-sectional area of the inner barrel cavity of the stopper barrel 301 such that the floating body pieces 432 do not move out of the third container 300 from the stopper barrel 302.

In addition, the locking and blocking device 430 may include a floating baffle that is floatingly disposed in the third fluid chamber 302 of the third container 300, and a floating baffle may be correspondingly engaged with both the pipetting frame of the first pipetting structure 410 and the pipetting frame of the second pipetting structure 420. The first pipetting frame 414 and the second pipetting frame 424 can be limited by one floating spoiler at the same time, which is simple and convenient. For example, when the first pipetting frame 414 and the second pipetting frame 424 are integrated, both may be limited by a floating spoiler.

In addition, the locking and blocking device 430 may also include one floating spoiler floating on each side of the third liquid chamber 302 of the third container 300, and the two floating spoilers may be correspondingly matched with the pipetting frame (the first pipetting frame 414) of the first pipetting structure 410 and the pipetting frame (the second pipetting frame 424) of the second pipetting structure 420 at the same time. Specifically, the first pipetting frame 414 and the second pipetting frame 424 may be simultaneously limited, i.e. each floating spoiler simultaneously limits the first pipetting frame 414 and the second pipetting frame 424; or the first pipetting frame 414 and the second pipetting frame 424 are limited by two floating spoilers, respectively, i.e. the first pipetting frame 414 is limited by one floating spoiler and the second pipetting frame 424 is limited by the other floating spoiler.

More (more than two) floating spoilers may be provided to limit the first and second pipetting frames 414, 424 as desired.

In addition, it should be noted that the above-mentioned liquid dispensing assembly 400 can be applied to a cleaning apparatus having a floor washing function, and can also be applied to other apparatuses requiring intermittent/uninterrupted feeding of mixed solutions in equal proportions.
