Referring to fig. 1 to 10 of the drawings accompanying the present application, a pneumatic dispensing device according to a preferred embodiment of the present invention is disclosed and illustrated in the following description, wherein the pneumatic dispensing device is configured to dispense a sample tube 100, for example, the pneumatic dispensing device is configured to dispense the sample tube 100 from a storage location to a use location to allow the use of the sample tube 100 in the use location. Specifically, the pneumatic transport device includes a transport tube 10 and an adjusting mechanism 20, wherein the pneumatic transport device is configured to allow the sample tube 100 to be driven to be transported along a transport path formed by the transport tube 10 after the adjusting mechanism 20 adjusts the orientation of the sample tube 100.

Specifically, the transmission pipeline 10 has a transmitting end 11, a receiving end 12 corresponding to the transmitting end 11, and a transmission channel 13 extending between the transmitting end 11 and the receiving end 12, wherein the transmission pipeline 10 allows gas to flow from the transmitting end 11 to the receiving end 12 along a transmission path formed by the transmission channel 13, and wherein the adjusting mechanism 20 is disposed at the transmitting end 11 of the transmission pipeline 10. The sample tube 100, which is adjusted to face backwards by the adjusting mechanism 20, can be driven by gas to be transmitted from the transmitting end 11 of the transmission pipeline 10 to the receiving end 12 along the transmission path formed by the transmission channel 13 of the transmission pipeline 10.

For example, in an application example of the pneumatic transmission device of the present invention, the transmitting end 11 of the transmission pipeline 10 is disposed at the storage location, and the receiving end 12 of the transmission pipeline 10 is disposed at the use location, so that the sample tube 100 can be driven to be transmitted from the storage location to the use location along the transmission path formed by the transmission channel 13 of the transmission pipeline 10.

Preferably, the diameter of the transport channel 13 of the transport channel 10 is slightly larger than the diameter of the sample tube 100, so that, on the one hand, the sample tube 100 can be driven by gas to be transported along the transport channel 13 of the transport channel 10, and, on the other hand, the orientation of the sample tube 100 does not change during the transport of the sample tube 100 along the transport path formed by the transport channel 13 of the transport channel 10.

It is worth mentioning that the material of the transfer duct 10 is not limited in the pneumatic dispensing device of the present invention, for example, the transfer duct 10 may be blow-molded from a plastic material. In addition, the transport pipeline 10 may be a complete longer pipe body if the distance between the storage place and the use place is short, and correspondingly, the transport pipeline 10 may be spliced by more than two shorter pipe bodies if the distance between the storage place and the use place is long.

Further, the adjusting mechanism 20 includes an adjusting member 21, and the adjusting member 21 has a holding through hole 211 penetrating through two opposite sides of the peripheral wall of the adjusting member 21, so as to allow two openings of the holding through hole 211 to be formed on two opposite sides of the peripheral wall of the adjusting member 21, respectively.

The adjusting element 21 is arranged at the transmitting end 11 of the transmission pipeline 10, wherein the adjusting element 21 has a receiving state and a transmitting state, and the adjusting element 21 is arranged to be switchable between the receiving state and the transmitting state. When the adjustment member 21 is in the receiving state, one of the sample tubes 100 can be allowed to enter the holding through-hole 211 of the adjustment member 21, and correspondingly, when the adjustment member 21 is in the sending state, the sample tube 100 can be allowed to enter the transport channel 13 of the transport tube 10 from the holding through-hole 211 of the adjustment member 21.

Preferably, the adjusting element 21 is rotatably disposed at the transmitting end 11 of the transmission pipeline 10, so that the adjusting element 21 can be switched between the receiving state and the transmitting state when the adjusting element 21 is driven to rotate at the transmitting end 11 of the transmission pipeline 10, that is, the adjusting element 21 can be switched from the receiving state to the transmitting state and from the transmitting state to the receiving state when the adjusting element 21 is driven to rotate at the transmitting end 11 of the transmission pipeline 10. It is understood that the adjustment element 21 can be maintained in the receiving state after being driven to rotate at the transmitting end 11 of the transmission pipeline 10 to switch from the transmitting state to the receiving state, and the adjustment element 21 can be maintained in the transmitting state after being driven to rotate at the transmitting end 11 of the transmission pipeline 10 to switch from the receiving state to the transmitting state.

More preferably, during the rotation of the transmitting end 11 of the transmission pipeline 10 when the adjusting element 21 is driven, the opening of the transmission channel 13 of the transmission pipeline 10 formed at the transmitting end 11 can always correspond to the peripheral wall of the adjusting element 21, so that the opening of the transmission channel 13 of the transmission pipeline 10 formed at the transmitting end 11 corresponds to the opening of the retaining through hole 211 of the adjusting element 21 formed at the peripheral wall of the adjusting element 21 when only the adjusting element 21 is allowed to be driven to rotate, and the transmission channel 13 of the transmission pipeline 10 and the retaining through hole 211 of the adjusting element 21 are communicated.

In this preferred example of the pneumatic routing device shown in fig. 1 to 10, the adjustment element 21 of the adjustment mechanism 20 has a disk shape with two opposite sides and a peripheral wall extending between the two opposite sides, wherein the holding through holes 211 are provided to penetrate through opposite sides of the peripheral wall of the adjustment element 21 so as to pass through a central position of the adjustment element 21, in such a manner that a distance between the peripheral walls of the transport duct 10 and the adjustment element 21 is maintained during rotation of the adjustment element 21 provided at the transmitting end 11 of the transport duct 10. Alternatively, in other examples of the pneumatic dispensing device of the present invention, the adjusting element 21 of the adjusting mechanism 20 may be flat with a cross section of triangle, quadrangle, or pentagon.

Further, the adjusting mechanism 20 includes a driving shaft 22, wherein the driving shaft 22 has a connecting end 221 and a driving end 222 corresponding to the connecting end 221, the connecting end 221 of the driving shaft 22 is connected to the sidewall of the adjusting element 21, and when the driving end 222 of the driving shaft 22 is driven, the driving shaft 22 can drive the adjusting element 21 to rotate synchronously with the transmitting end 11 of the transmission pipeline 10.

Preferably, the central axis of the driving shaft 22 coincides with the central axis of the adjusting member 21, so that when the driving shaft 22 is driven to rotate by taking the central axis of the driving shaft 22 as a rotating axis, the driving shaft 22 can drive the adjusting member 21 to rotate by taking the central axis of the adjusting member 21 as a rotating axis.

It is worth mentioning that the driving shaft 22 and the adjustment member 21 may be a split structure, and the connection end 221 of the driving shaft 22 is mounted to a sidewall of the adjustment member 21. Alternatively, the driver end 222 and the adjustment member 21 may be a unitary structure with the drive shaft 22 extending from a side wall of the adjustment member 21.

Further, as shown in fig. 1 to 3, the pneumatic routing device includes a motor 30, wherein the driving shaft 22 extends to the motor 30 and is drivably connected to the motor 30 to allow the motor 30 to drive the driving shaft 22 to rotate with the central axis of the driving shaft 22 as a rotation axis.

With continued reference to fig. 1-3, the pneumatic dispensing device includes a limiting mechanism 40, wherein the limiting mechanism 40 has a limiting space 41 and a first notch 42 communicating with the limiting space 41. The opening of the transmission channel 13 of the transmission pipeline 10 formed on the transmitting end 11 corresponds to the first notch 42 of the limiting mechanism 40. The adjusting element 21 of the adjusting mechanism 20 is rotatably held in the stopper space 41 of the stopper mechanism 40 in such a manner that a peripheral wall of the adjusting element 21 and an inner wall of the stopper mechanism 40 for forming the stopper space 41 correspond to each other, so that the holding through hole 211 of the adjusting element 21 can correspond to the first notch 42 of the stopper mechanism 40 or to the inner wall of the stopper mechanism 40 for forming the stopper space 41.

For example, during the process that the adjusting element 21 is driven to rotate by the transmitting end 11 of the transmission pipeline 10 to switch from the receiving state to the transmitting state, the opening of the holding through hole 211 of the adjusting element 21 on the lower side can correspond to the inner wall of the limiting mechanism 40 for forming the limiting space 41, so as to avoid the sample tube 100 from falling off from the holding through hole 211 of the adjusting element 21, and thus during the process that the adjusting mechanism 20 adjusts the orientation of the sample tube 100 by rotating the adjusting element 21, the sample tube 100 can be reliably held by the holding through hole 211 of the adjusting element 21, so that the adjusting element 21 adjusts the orientation of the sample tube 100 by rotating.

The openings of the holding penetration holes 211 of the adjusting member 21 at the lower side selectively correspond to the first stopper surface 431 of the first stopper arm 43 and the second stopper surface 441 of the second stopper arm 44. That is, the first stopper surface 431 of the first stopper arm 43 and the second stopper surface 441 of the second stopper arm 44 form an inner wall of the stopper mechanism 40 for forming the stopper space 41.

Further, the position limiting mechanism 40 includes a retaining arm 45, wherein the first position limiting arm 43 and the second position limiting arm 44 are respectively disposed on the retaining arm 45, so as to maintain the relative positions of the first position limiting arm 43 and the second position limiting arm 44 by the retaining arm 45. It is worth mentioning that the first stopper arm 43, the second stopper arm 44 and the holder arm 45 of the stopper mechanism 40 may be a split structure so that the first stopper arm 43 and the second stopper arm 44 can be mounted to the holder arm 45. Alternatively, the first check arm 43, the second check arm 44, and the retaining arm 45 may be a unitary structure.

Further, the limiting mechanism 40 has a second notch 46, wherein the second notch 46 is communicated with the limiting space 41. Preferably, the first notch 42 and the second notch 46 of the limiting mechanism 40 are communicated with the limiting space 41 at two opposite sides of the limiting space 41, so that the first notch 42 and the second notch 46 correspond to each other. For example, in the preferred example of the pneumatic transport device shown in fig. 1-10, the pneumatic transport device can transport the sample tube 100 upward such that the first notch 42 is located at an upper portion of the position limiting mechanism 40 to form an upper notch and correspondingly, the second notch 46 is located at a lower portion of the position limiting mechanism 40 to form a lower notch.

The driving mechanism 50 further comprises a driving portion 52, wherein the driven end 511 of the driving rod 51 is drivably connected to the driving portion 52 to allow the driving portion 52 to drive the free end 512 of the driving rod 51 to extend to the holding through hole 211 of the adjusting element 21. Preferably, the driving rod 51 is configured to further extend to the transmission channel 13 of the transmission pipeline 10, so as to drive the sample tube 100 to make the sample tube 100 integrally enter the transmission channel 13 of the transmission pipeline 10.

Preferably, at least one of the two supporting wheels 71 is a driving wheel for driving the caterpillar part 72 to rotate. For example, the supporting wheel 71 of the two supporting wheels 71 that is close to the adjusting element 21 is a driving wheel, so that the track portion 72 can be driven to move in the direction of the adjusting element 21, so that the sample tubes 100 supported by the track portion 72 of the feeding mechanism 70 can be guided into the holding through holes 211 of the adjusting element 21.

Preferably, the track part 72 has a guide slot 721, wherein the guide slot 721 is formed along the extending direction of the track part 72. The sample tube 100 can be held in the guide slot 721 of the track part 72 to prevent the sample tube 100 from falling off from the track part 72 when the track part 72 drives the sample tube 100 to move toward the holding through hole 211 of the adjusting element 21.
