Further, the heat conducting plate 22, the limit baffle 23 and the support plate 25 may be annular disks, and the main surfaces may be parallel to the main surface of the support plate 21. Specifically, one main surface of the heat conducting plate 22 may abut against one side of one main surface of the supporting plate 21, the limiting baffle 23 may be disposed at an interval with the heat conducting plate 22 and located on one side of the heat conducting plate 22 away from the supporting plate 21, and the supporting plate 25 is disposed on one side of the limiting baffle 23 away from the heat conducting plate 22 and disposed at an interval with the limiting baffle 23. The main surfaces of the heat conducting plate 22, the limit baffle 23 and the bearing plate 25 can all be disk surfaces with larger areas.

Wherein, the heat conducting plate 22 and the limit baffle 23 can be provided with a plurality of screw holes arranged at intervals, and then the heat conducting plate 22 and the limit baffle 23 are fixed on the supporting plate 21 by the screw connection mode. Wherein, the screw evenly distributed to make holding pipe 24 can keep good contact with heat-conducting plate 22 under the effect of the pressure force that the screw connection and produce, further improve heat conduction efficiency of heat-conducting plate 22 to holding pipe 24, and then improve the uniformity to the heating temperature of every holding pipe 24.

Specifically, the supporting plate 21 is provided with a plurality of positioning holes 211 which are spaced from each other and uniformly distributed along the circumference of the supporting plate 21, and the heat conducting plate 22 is defined with a plurality of guiding holes 221 which are also spaced from each other and uniformly distributed along the circumference of the heat conducting plate 22. The accommodating tubes 24 are disposed at intervals and abut between the heat-conducting plate 22 and the supporting plate 25, and correspond to the positioning holes 211 and the guiding holes 221. Each accommodating tube 24 defines an accommodating space 242 with two open ends, the opening facing the heat conducting plate 22 is a first opening 241, wherein the positioning hole 211 and the corresponding guiding hole 221 can correspond to the first opening 241 of the corresponding accommodating tube 24 and further communicate with the corresponding accommodating space 242; the opening facing the supporting plate 25 is a second opening 244, and the supporting plate 25 abuts against the accommodating tube 24 at the second opening 244 to close the second opening 244 of the accommodating space 242. Furthermore, the supporting plate 21, the heat conducting plate 22, the accommodating tube 24 and the supporting plate 25 together define an accommodating space composed of the corresponding positioning hole 211, the guiding hole 221, the first opening 241 and the accommodating space 242, and the accommodating space is used for accommodating the sample accommodating part 5000. Specifically, the sample container 5000 may pass through the corresponding positioning hole 211, the corresponding guide hole 221, and the corresponding first opening 241 and be placed in the accommodating space 242, and when being placed in the accommodating space 242, the bottom of the sample container 5000 is supported on the supporting plate 25, wherein a step surface may be further disposed at the opening of the sample container 5000 to cooperate with the corresponding positioning hole 211 on the supporting plate 21, and the accommodating space formed by the positioning hole 211, the corresponding guide hole 221, and the corresponding accommodating space 242 is sealed at the positioning hole 211, so as to form a relatively independent cavity, and reduce the influence between the incubation environments in the accommodating spaces corresponding to different sample containers 5000 to a certain extent.

Further, the supporting plate 25 may define a plurality of positioning grooves 251 recessed in a direction away from the limit stop 23, and the positioning grooves 251 may respectively correspond to the accommodating tubes 24 one by one, and may have a shape matching the bottom of the corresponding sample container 5000. Thus, when the sample container 5000 is placed in the accommodating space 242, the positioning groove 251 can accommodate the bottom of the sample container 5000, so that the sample container 5000 can be placed in the accommodating space 242 more stably, and the shaking during the rotation of the incubation plate 20 is reduced.

It should be noted that, in an embodiment, the accommodating tube 24 has a flange 243 at the periphery of the first opening 241, and abuts against the heat conducting plate 22 through the main surface of the flange 243, and since the heat conducting plate 22 is used for receiving heat and further conducting heat, the accommodating tube 24 receives the heat conducted by the heat conducting plate 22 through contacting with the heat conducting plate 22, so as to heat the air in the accommodating space 242 to raise the temperature thereof, and further, to heat the sample accommodating member 5000 placed in the accommodating space 242. Note that the main surface of the flange 243 refers to a surface of the flange 243 having a large area.

In the related art, the accommodating tube 24 is not provided with the flange 243 at the first opening 241, and the end portion of the accommodating tube 24 directly contacts with the heat conducting plate 22 through the first opening 241 to receive the heat conducted by the heat conducting plate 22, as described above, the flange 243 of the accommodating tube 24 contacts with the heat conducting plate 22 in the embodiment, and due to the structural characteristics of the flange 243, the contact area between the accommodating tube 24 and the heat conducting plate 22 can be increased, so as to improve the efficiency of heat conduction, further accelerate the rate of heating the sample accommodating member 5000, and improve the efficiency of incubating the sample in the sample accommodating member 5000.

Further, in an embodiment, the limiting baffle 23 can abut against the side of the flange 243 far away from the heat conducting plate 22, so as to constrain the flange 243 between the limiting baffle 23 and the heat conducting plate 22, so that the flange 243 and the heat conducting plate 22 are more firmly contacted, which is helpful to improve the heat conducting efficiency of the heat conducting plate 22 to the accommodating tube 24, and further can improve the consistency of the heating temperature of the heat conducting plate 22 to each accommodating tube 24. Specifically, both side main surfaces of the flange 243 are respectively abutted against the heat-conducting plate 22 and the limit stopper 23 so as to be sandwiched therebetween.

Specifically, the limiting baffle 23 may define a plurality of through holes 231, wherein the plurality of through holes 231 correspond to the plurality of accommodating tubes 24 one by one, and the limiting baffle 23 may be sleeved on the periphery of the corresponding plurality of accommodating tubes 24 through the plurality of through holes 231, and abut against one side of the flange 243 away from the heat conducting plate 22, and further constrain the tube body of the accommodating tube 24.

Further, the supporting plate 21 defines a first mounting groove 212, a second mounting groove 213 and a third mounting groove 214 which are disposed toward the heat conducting plate 22 and are recessed along a direction departing from the heat conducting plate 22, and the heating member 26, the temperature sensor and the temperature protection switch are respectively mounted in the first mounting groove 212, the second mounting groove 213 and the third mounting groove 214.

The first installation groove 212, the second installation groove 213 and the third installation groove 214 may be connected or spaced apart from each other, and the shape, size and the like may be set according to the shape and size of the heating element 26, the temperature sensor and the temperature protection switch to be installed correspondingly.

Further, the heat conducting plate 22 can be disposed at the openings of the first mounting groove 212, the second mounting groove 213 and the third mounting groove 214, so as to close the corresponding mounting grooves at the corresponding openings, and abut against the heating element 26, the temperature sensor and the temperature protection switch. Through the sealing of the heat conducting plate 22, on one hand, the overall structure of the incubation tray 20 is more compact, and on the other hand, liquid can be effectively prevented from splashing on electrical elements such as the heating member 26, so that the safety performance and the service life of the incubation tray 20 can be improved.

It is noted that the heating member 26 is configured to generate heat, and the heat conduction plate 22 receives and conducts the heat generated by the heating member 26 by abutting against the heating member 26.

Further, the limiting baffle 23 further defines a preset number of avoiding holes 232, wherein the avoiding holes 232 and the through holes 231 are arranged at intervals. Specifically, the plurality of through holes 231 may be located near the outer ring along the circular ring-shaped limit baffle 23, and the avoiding hole 232 may be located at a position of the limit baffle 23 closer to the center with respect to the through holes 231. The number of the avoiding holes 232 may be one or more, and may be specifically set according to actual requirements, which is not specifically limited herein.

The number of the heat conduction columns 27 can be consistent with the number of the avoiding holes 232, and is in one-to-one correspondence with the avoiding holes 232, each heat conduction column 27 can pass through the corresponding avoiding hole 232 to be supported and arranged between the heat conduction plate 22 and the bearing plate 25 to receive the heat conducted by the heat conduction plate 22, and further conduct the received heat to the bearing plate 25, because the sample containing piece 5000 is in direct contact with the bearing plate 25, the bearing plate 25 can further transmit the received heat to the sample containing piece 5000, and thus the sample in the sample containing piece 5000 is heated.

The heat-conducting columns 27 are arranged to realize the heat transfer as described above, and further connect the heat-conducting plate 22, the limit baffle 23 and the support plate 25.

It should be noted that the heat conducting plate 22 can raise the overall temperature in the incubation plate 20 by heating the air in the incubation plate 20 and maintain the temperature in the incubation plate 20 stable, in addition to direct heat transfer by direct contact with other components.

Specifically, in the present embodiment, the heat-conducting columns 27 can further conduct the heat conducted by the heat-conducting plate 22 to the support plate 25 through the connection with the heat-conducting plate 22, thereby directly heating the sample-accommodating member 5000 placed on the support plate 25. Further, the heat conducting plate 22, the heat conducting columns 27, the accommodating tubes 24 and the supporting plates 25 can also be used for conducting heat generated by the heating element 26 to air in the incubation groove 11, heating the air in the incubation groove 11, so as to heat the sample accommodating part 5000 through the heated air, and the accommodating tubes 24 and the supporting plates 25 can directly heat the air in the accommodating channel, and each accommodating tube 24 is relatively independent, thereby reducing the influence of the external environment on the temperature in the accommodating tube 24, so that the sample accommodating part 5000 accommodated therein and the sample therein can keep relatively independent temperature environment to a certain extent, reducing the mutual influence and interference between different accommodating parts and corresponding samples, and reducing the fluctuation of the temperature. In this way, the arrangement of the heat-conducting plate 22, the heat-conducting columns 27 and the supporting plate 25 with the heat-conducting function can heat the sample accommodating part 5000 by the solid direct heating and air bath mode, so as to improve the efficiency of incubating the sample in the sample accommodating part 5000.

In addition, because the incubation groove 11 is relatively closed, the heated air in the incubation groove has relatively less outward diffusion, and under the driving of the power mechanism 300, the incubation tray 20 can rotate in the incubation groove 11, and the rotation of the incubation tray 20 promotes the air fluidity in the incubation groove 11 to be enhanced, thereby contributing to improving the uniformity of the air temperature in the incubation groove 11 to a certain extent. Furthermore, the heating speed can be increased by the mode of heating the solid directly and the air bath simultaneously, and the temperature fluctuation is small.

In this embodiment, the heat conducting plate 22, the heat conducting columns 27, the supporting plate 25 and the accommodating tube 24 all have a heat conducting function, and in an application scenario, the three components can be made of heat conducting materials, such as aluminum, aluminum alloy, copper alloy, stainless steel, or polymer composite materials with a heat conducting function, and can be produced through corresponding molds. In addition, the materials of the housing 10, the cover 30 and the supporting plate 21 can be materials which are not easy to conduct heat, for example, the housing 10 may be made of bakelite which is not easy to conduct heat, the cover 30 may be made of Acrylonitrile Butadiene Styrene (ABS), the supporting plate 21 may be made of plastic or Polyoxymethylene (POM), since the cover 30 covers the first opening 241 of the incubation well 11, the support plate 21 and the associated connection structure cover the second opening 244 of the incubation well 11, so that the incubation groove 11 forms a relatively closed space, thereby effectively reducing the outward diffusion of air in the incubation groove 11, reducing the outward conduction of heat, and the incubation tray 20 can rotate in the incubation groove 11 under the driving of the power mechanism 300, thereby enhancing the air flow inside the incubation groove 11 and contributing to the improvement of the uniformity of the air temperature inside the incubation groove 11.

It should be further noted that the heat conducting plate 22 and the supporting plate 25 can be made of sheet metal, and the accommodating tube 24 can be made of standard aluminum tube by cutting, so that the instrument can be conveniently processed and assembled, and the cost is low, thereby improving the overall economy of the instrument.

After the sample container 5000 is placed in the accommodating tube 24, a certain gap may exist between the outer sidewall of the sample container 5000 and the inner sidewall of the accommodating tube 24. Further, the diameter of the positioning hole 211 may be slightly larger than the outer diameter of the sample-accommodating member 5000, so as not to affect the smooth placement of the sample-accommodating member 5000, and also to limit the central offset of the sample-accommodating member 5000 with respect to the positioning hole 211; moreover, the sidewall of the positioning hole 211 can be chamfered to guide the sample holder 5000.

The above embodiments are merely examples and are not intended to limit the scope of the present disclosure, and all modifications, equivalents, and flow charts using the contents of the specification and drawings of the present disclosure or those directly or indirectly applied to other related technical fields are intended to be included in the scope of the present disclosure.
