Embodiments of the present invention will be described below with reference to fig. 1 to 4. It is to be understood that the following description is only exemplary of the present invention and is not intended to limit the present invention.

As shown in fig. 1, the utility model provides a pneumatic device, include: a first accommodating cavity 103 and an air inlet pipe 101, wherein the first accommodating cavity 103 is communicated with the conveying pipe 102, and the first accommodating cavity 103 is used for accommodating a part of the sample box 300; an air inlet pipe 101 is communicated with the first accommodating chamber 103, and the air inlet pipe 101 is used for providing positive pressure or negative pressure air flow.

The air inlet pipe 101 is arranged to communicate with the first accommodating chamber 103, that is, after positive or negative pressure air flows pass through the first accommodating chamber 103, negative pressure is generated at upper and lower ends of the sample cartridge 300 of the first accommodating chamber 103, so that the sample cartridge 300 is transferred to a designated position through the transfer pipe 102. The reasonable layout of the position of wind power is realized at the air inlet pipe 101 of the first accommodating cavity 103 through the arrangement, so that the height of the whole wind-driven device is effectively reduced.

Further, the side wall of the first accommodating chamber 103 is provided with a tuyere 104, and the tuyere 104 is communicated with the air inlet pipe 101.

With continued reference to fig. 1, in one embodiment of the present invention, the pneumatic device further comprises a second receiving chamber 202, the second receiving chamber 202 being configured to receive another portion of the sample cartridge 300; that is, a part of the sample cartridge 300 is placed in the first receiving chamber 103, and another part is placed in the second receiving chamber 202, and the first receiving chamber 103 and the second receiving chamber 202 enclose the entire sample cartridge 300.

Specifically, in the first state, the first accommodating chamber 103 and the second accommodating chamber 202 are engaged, and the air inlet pipe 101 provides positive pressure or negative pressure airflow. That is, the first accommodating cavity 103 and the second accommodating cavity 202 are fastened to form an incompletely sealed space, and when the sample cartridge 300 is sent, the air inlet pipe 101 provides positive pressure air flow, and the positive pressure air flow causes a pressure difference to be formed between the top and the bottom of the sample cartridge 300, so that the sample cartridge 300 enters the conveying pipe 102 from the first accommodating cavity 103 and the second accommodating cavity 202, and is conveyed to a specified position, and the sending of the sample cartridge 300 is completed.

For example, when the sample cartridge 300 is received, the first receiving chamber 103 and the second receiving chamber 202 are engaged, the air inlet pipe 101 provides a negative pressure air flow to provide a suction force to the sample cartridge 300 conveyed from the conveying pipe 102, so that the sample cartridge 300 smoothly enters the first receiving chamber 103 and the second receiving chamber 202, and the receiving of the sample cartridge 300 is completed.

Further, in the second state, the first receiving chamber 103 is separated from the second receiving chamber 202, and the air flow from the air inlet duct 101 is stopped. In other words, after the transmission and reception of the sample cartridge 300 are completed, the first receiving chamber 103 and the second receiving chamber 202 are separated, and the air flow of the air inlet duct 101 is closed. That is, the pneumatic device of the present invention can complete the transmission of the sample cartridge 300 and the reception of the sample cartridge 300.

As shown in fig. 1 and fig. 2, in another embodiment of the present invention, the pneumatic device further includes a power mechanism 201, and the power mechanism 201 is connected to the second accommodating cavity 202 for driving the second accommodating cavity 202 to be locked with and separated from the first accommodating cavity 103.

Further, in the first state, the power mechanism 201 drives the second accommodating cavity 202 to approach the first accommodating cavity 103; in the second state, the power mechanism 201 drives the second accommodating cavity 202 to be far away from the first accommodating cavity 103. For example, the power mechanism 201 may be a rod non-rotating cylinder, and an expansion rod of the rod non-rotating cylinder is connected to the second accommodating chamber 202, so as to drive the second accommodating chamber 202 to move linearly.

Furthermore, in other optional embodiments of the present invention, the pneumatic device further comprises a delivery pipe 102, and the delivery pipe 102 is communicated with one end of the first accommodating cavity 103; the axes of the delivery pipe 102, the first accommodating cavity 103, the second accommodating cavity 202 and the power mechanism 201 are all on the same straight line.

For example, a first accommodating cavity 103 is arranged below the conveying pipe 102, a second accommodating cavity 202 is arranged below the first accommodating cavity 103, and a power mechanism 201 is arranged below the second accommodating cavity 202, and on the vertical axis, the axis of the conveying pipe 102, the axis of the first accommodating cavity 103, the axis of the second accommodating cavity 202, and the axis of the power mechanism 201 all coincide. In other words, the axis of the sample cartridge 300 coincides with the axes of the first receiving chamber 103 and the second receiving chamber 202. The sample cartridge 300 has a smaller diameter than the delivery tube 102 to facilitate removal and receipt from the delivery tube 102.

As shown in fig. 1 to 3, in an embodiment of the present invention, the pneumatic device further includes a first sample box 100 and a second sample box 200, the first accommodating chamber 103 is formed in the first sample box 100, and the second accommodating chamber 202 is formed in the second sample box 200. Specifically, the inner cavity of the first sample box 100 is the first accommodating cavity 103, the first sample box 100 is a vertical penetrating structure, the upper end of the first sample box 100 is communicated with the conveying pipe 102, and the lower end of the second sample box 200 is an open end for being buckled with the upper end of the second sample box 200 to form an incompletely-closed cavity. The lower end of the second sample chamber 200 is connected to the actuating unit 201, and the actuating unit 201 pushes the second sample chamber 200 to move toward and away from the first sample chamber 100.

For example, when the sample cartridge 300 is sent, the bottom of the sample cartridge 300 is first placed in the second receiving chamber 202 of the second sample box 200. The power mechanism 201 pushes the second sample container 200 to move linearly, and the second sample container is buckled with the first sample container 100, so that the upper portion of the sample box 300 is placed in the first accommodating cavity 103 of the first sample container 100.

An air opening 104 communicated with the air inlet pipe 101 is formed in the side wall of the first sample box 100, so that the air inlet pipe 101 is communicated with the first accommodating cavity 103.

Referring to fig. 1, a tapered surface 105 is formed on an inner wall of one end of the first sample box 100, which is in contact with the second sample box 200, and the tapered surface 105 is used for air outlet. In other words, the tapered surface 105 is provided at the lower end of the first sample container 100 to be outwardly expanded, and the tapered surface 105 is equivalent to enlarging the inner diameter of the end of the first sample container 100. It is also equivalent to that a ventilation pipeline is arranged between the air supply opening 104 and the second accommodating cavity 202.

For example, when the sample box 300 is sent, after the first sample box 100 is fastened to the second sample box 200, the tapered surface 105 allows the airflow entering from the air inlet pipe 101 to better flow into the second receiving cavity 202 of the second sample box 200 along the tapered surface 105, so that the pressure difference between the bottom and the top of the sample box 300 can be quickly generated, and the sample box 300 can be quickly sent.

Referring to fig. 2 and 3, in another alternative embodiment of the present invention, the pneumatic device further comprises a clamping mechanism 203, and one end of the clamping mechanism 203 is disposed in the second accommodating chamber 202; the clamping mechanism 203 is used for clamping the sample cartridge 300 placed in the second receiving chamber 202.

Further, when the sample cartridge 300 is sent, the clamping mechanism 203 releases the sample cartridge 300 in the first state. Specifically, the sample box 300 is placed in the second sample box 200, the clamping mechanism 203 clamps the sample box 300 to rise, and the sample box 300 is buckled with the first sample box 100, that is, in the first state, the air inlet pipe 101 starts to ventilate, and the clamping mechanism 203 releases the sample box 300, so that the sample box 300 can be sent smoothly.

In the second state, the clamping mechanism 203 clamps the sample cartridge 300. During the ascent of the second sample tank 200, the clamp mechanism 203 is in a state of clamping the sample cartridge 300, or, when the sample cartridge 300 is dropped from the transfer pipe 102 into the second sample tank 200 while receiving the sample cartridge 300, the clamp mechanism 203 clamps the sample cartridge 300 dropped into the second sample tank 200, and then the second sample tank 200 is descended.

For example, the clamping mechanism 203 is a clamping cylinder, the clamping cylinder is installed on both sides of the second sample box 200, and the telescopic end of the clamping cylinder is placed in the second sample box 200, i.e. in the second accommodating chamber 202. Clamping and unclamping of the sample cartridge 300 is achieved by the telescoping end.

As shown in fig. 3, in the preferred embodiment of the present invention, the pneumatic device further comprises a photoelectric switch 204, the photoelectric switch 204 is electrically connected to the controller, the clamping mechanism 203 is electrically connected to the controller, and the photoelectric switch 204 is used for detecting the arrival and departure of the sample cartridge 300. Wherein the photoelectric switch 204 is mounted on the second sample chamber 200.

Specifically, the controller drives the clamping mechanism 203 to clamp the sample cartridge 300 after the photoelectric switch 204 detects that the sample cartridge 300 is reached, and drives the clamping mechanism 203 to release the clamping action after the photoelectric switch 204 detects that the sample cartridge 300 is separated. For example, when the sample cartridge 300 is sent, the sample cartridge 300 is placed in the second sample box 200, the photoelectric switch 204 detects the arrival of the sample cartridge 300, and sends a signal to the controller, and the controller sends a command to the clamping mechanism 203 to control the clamping mechanism 203 to clamp the sample cartridge 300.

Of course, after the first sample container 100 and the second sample container 200 are engaged, the controller can send a command to the clamping mechanism 203, and the clamping mechanism 203 releases the clamping action, i.e., releases the clamping jaws, so that the sample cartridge 300 can be smoothly sent out.

When the sample cartridge 300 is received and the sample cartridge 300 falls from the delivery tube 102 into the second sample chamber 200, the photoelectric switch 204 detects the arrival of the sample cartridge 300 and sends a signal to the controller, and the controller sends a command to the clamping mechanism 203, and the clamping mechanism 203 clamps the sample cartridge 300.

As shown in fig. 4, in other embodiments of the present invention, the pneumatic device further includes a cabinet 301 and a cabinet door 302, the first accommodating cavity 103, the second accommodating cavity 202 and the power mechanism 201 are disposed in the cabinet 301, and the cabinet door 302 is mounted on the cabinet 301. That is, the first sample container 100, the second sample container 200, the clamping mechanism 203, the power mechanism 201, the delivery pipe 102 and the air inlet pipe 101 are all disposed in the cabinet 301. The sample box 300 is taken and placed by arranging the cabinet door 302 on the cabinet body 301.

Wherein, the lock of the cabinet door 302 is electrically connected with the controller, and the controller is electrically connected with the power mechanism 201. Specifically, when the sample box 300 is sent, a door opening instruction is sent to the controller, the controller drives the power mechanism 201 to move down, that is, the power mechanism 201 is placed at the initial position, a signal is fed back to the controller after the power mechanism 201 is in place, the controller opens the door lock, the cabinet door 302 is opened, and the sample box 300 is placed in the second sample box 200. The door 302 is closed and the lock of the door 302 is locked. At this time, the photoelectric switch 204 detects the sample cartridge 300, and the clamping mechanism 203 clamps the sample cartridge 300. That is, the cabinet door 302 lock forms a safety interlock with the power mechanism 201.

When the sample box 300 is received, a door opening command is sent to the controller, the controller drives the power mechanism 201 to move downwards, namely, the power mechanism 201 is placed at an initial position, after the power mechanism 201 is in place, a signal is fed back to the controller, the controller sends the door opening command to the door lock, meanwhile, the controller sends a command to the clamping mechanism 203, and the clamping mechanism 203 releases the clamping jaw to release the clamping state. After the door 302 is opened, the sample box 300 is taken out, the door 302 is closed, and the door 302 is locked.

The utility model also provides a pneumatic system, including two sets of pneumatic device in the above-mentioned embodiment, the conveyer pipe 102 of two sets of pneumatic device passes through the connecting tube intercommunication.

For example, two sets of pneumatic devices include a first pneumatic device and a second pneumatic device, with the tube 102 of the first pneumatic device and the tube 102 of the second pneumatic device being in communication with one another via a connecting conduit to enable transfer of samples within the sample cartridge 300 between the first pneumatic device and the second pneumatic device.

In the transmission process, the first pneumatic device and the second pneumatic device can be used as a receiving cabinet or a sending cabinet and have the functions of sending and receiving.
