Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1

[0020] See also Figure 1-Figure 4 , a parallel concentrator shown in the figure includes a sample rack 102 arranged on a base 101, a plurality of sample tubes 104 are placed in the sample rack 102 through a sample plate 103, a sample cover plate 105 for sealing the sample tubes 104 is provided on the sample rack 102, an air pipe 106 is provided on one side of the sample cover plate 105, a plurality of conduits 107 are provided on one side of the sample cover plate 105 close to the sample rack 102, and a control mechanism for controlling each conduit 107 is provided on the sample cover plate 105;

[0021] The control mechanism includes a first control plate 201 fixedly connected to one end of the conduit 107 close to the sample tube 104, a plurality of first control holes 205 are provided on the first control plate 201, a rotating shaft 202 is rotatably connected to the side of the first control plate 201 away from the sample tube 104, a second control plate 203 is provided on the side wall of the rotating shaft 202, a plurality of second control holes 204 are provided on the second control plate 203, each second control hole 204 is matched with the first control hole 205, and a driving mechanism for driving the second control plate 203 is provided on the conduit 107;

[0022] It should be noted here that: through the setting of the control mechanism, depending on whether the sample tube 104 is placed under the catheter 107, the passage of the catheter 107 is automatically controlled under the driving action of the driving mechanism and the pushing action of the pushing mechanism, without the need for manual operation, thereby improving the operating convenience of the parallel concentrator and the efficiency of the sample concentration experiment.

[0023] It is worth noting that: as a prior art, the specific structure and working principle of the parallel concentrator have been mastered by people in this field, and will not be elaborated here.

[0024] See also Figure 3 and Figure 4 The driving mechanism shown in the figure includes two guide rods 301 fixedly connected to the conduit 107 and arranged symmetrically with each other, the two guide rods 301 are slidably connected with sliding plates 302, a rack 303 is fixedly connected between the two sliding plates 302, a gear 304 is fixedly connected to the rotating shaft 202, the gear 304 and the rack 303 are meshed with each other, and a pushing mechanism for pushing the rack 303 is provided on the sample cover plate 105;

[0025] It should be noted that: by setting the driving mechanism, it is convenient to drive the second control plate 203 to rotate, so as to achieve the coincidence or stagger of the first control hole 205 and the second control hole 204 .

[0026] See also Figure 3 and Figure 4 , the side walls of the two guide rods 301 shown in the figure are sleeved with first springs 4, and the two ends of the two first springs 4 are respectively connected to the sliding plate 302 and the inner wall of the guide tube 107;

[0027] It should be noted here that: through the setting of the first spring 4, a reset effect is provided for the movement of the rack 303. When the sample cover 105 is removed from the sample tube 104, under the elastic action of the first spring 4, the rack 303 and the gear 304 are meshed and transmitted again, thereby further driving the second control plate 203 to rotate, so that the second control hole 204 is staggered with the first control hole 205, thereby closing the passage of the conduit 107.

[0028] Working principle: When using the parallel concentrator to concentrate a sample, first place the sample tube 104 containing the sample into the sample plate 103 on the sample rack 102, and then cover it with the sample cover plate 105;

[0029] During the process of covering the sample cover plate 105, when a sample tube 104 is placed under the conduit 107, the rack 303 is pushed to move under the pushing action of the pushing mechanism, so that the gear 304 is driven to rotate under the mutual meshing transmission action of the rack 303 and the gear 304, thereby further driving the second control plate 203 to rotate, so that the second control hole 204 on the second control plate 203 is matched with the first control hole 205 on the first control plate 201, thereby opening the passage between the conduit 107 and the sample tube 104. Since no sample tube 104 is placed under the remaining conduits 107, the staggered action of the first control hole 205 and the second control hole 204 makes the conduit 107 in a closed state, thereby avoiding gas leakage. Therefore, under the action of the control mechanism, whether the sample tube 104 is placed under the conduit 107 is used, and under the driving action of the driving mechanism and the pushing action of the pushing mechanism, the passage of the conduit 107 is automatically controlled without manual operation, thereby improving the convenience of operation of the parallel concentrator and the efficiency of the sample concentration experiment. Example 2

[0030] See also Figure 3 and Figure 4 , this embodiment further illustrates Example 1, the pushing mechanism shown in the figure includes a pushing ring 501 slidably connected to the side of the sample cover 105 close to the sample tube 104, the pushing ring 501 is concentrically arranged with the conduit 107, a pushing plate 502 is fixedly connected to the side of the pushing ring 501 close to the sample cover 105, a connecting plate 503 is slidably connected to the conduit 107, one end of the connecting plate 503 is connected to the rack 303, the other end of the connecting plate 503 is provided with an inclined surface 504, and the other end of the pushing plate 502 slides on the inclined surface 504;

[0031] It should be noted that: through the setting of the pushing mechanism, in the process of the sample cover plate 105 moving close to the sample rack 102, the pushing ring 501 will first abut against the end surface of the sample tube 104, so that under the pushing action, the pushing ring 501 will be pushed to move close to the sample cover plate 105, and further drive the pushing plate 502 to move close to the sample cover plate 105. When the pushing plate 502 abuts against the connecting plate 503, under the interaction force of the inclined surface 504 and the guiding action of the guide rod 301, the connecting plate 503 will be pushed to retract into the conduit 107.

[0032] When the connecting plate 503 is retracted into the conduit 107 , the rack 303 is pushed to move, thereby driving the second control plate 203 to rotate under the mutual meshing transmission action of the rack 303 and the gear 304 .

[0033] See also Figure 3 and Figure 4, the inner hole of the push ring 501 shown in the figure is matched with the outer circle of the catheter 107, and a rubber pad is provided on the side close to the sample tube 104;

[0034] It should be noted here that: by matching the inner hole of the push ring 501 with the outer circle of the conduit 107 , the sealing effect of the push ring 501 on the sample tube 104 is improved.

[0035] See also Figure 3 and Figure 4 The sample cover plate 105 shown in the figure is provided with a telescopic assembly for telescoping the push ring 501, and the telescopic assembly includes a plurality of telescopic tubes 601 fixedly connected to the sample cover plate 105 near the push ring 501, and a telescopic rod 602 is slidably connected to the telescopic tube 601, one end of the telescopic rod 602 is connected to the push ring 501, and the other end of the telescopic rod 602 is fixedly connected to a telescopic plate 603, and the other side of the telescopic plate 603 is fixedly connected to a second spring 604, and the other end of the second spring 604 is connected to the bottom wall of the telescopic tube 601;

[0036] It should be noted here that: the setting of the telescopic assembly provides guidance and reset functions for the movement of the push ring 501.
