[0038] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are 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.

[0039] See also Figures 1 to 6As shown, the embodiment of the utility model provides an incubation device 10, which includes a containing structure 100, a first incubation mechanism 200, a second incubation mechanism 300 and a base structure 400: the containing structure 100 is provided with a first cavity 111; the first incubation mechanism 200 includes a first incubation tray 210 and a first driving assembly 220 connected to the first incubation tray 210 and used to drive the first incubation tray 210 to rotate, and the first incubation tray 210 is rotatably accommodated in the first cavity 111; the second incubation mechanism 300 includes a second incubation tray 310 and a first driving assembly 220 connected to the first incubation tray 210 and used to drive the first incubation tray 210 to rotate. 10 is connected to and used for driving the second driving component 320 to rotate the second incubation tray 310, the second incubation tray 310 is suspended in the first cavity 111, the first incubation tray 210 is arranged in a ring shape and surrounded by the outer side of the second incubation tray 310, and the power of the second driving component 320 is located on the side of the first incubation tray 210 away from the first driving component 220; the base structure 400 includes a seat body 410 and a supporting component 420, the supporting component 420 is respectively connected to the seat body 410 and the containing structure 100, and the first driving component 220 is connected to the seat body 410.

[0040] In the incubation device 10 of the present embodiment, the first incubation tray 210 is arranged around the second incubation tray 310, the combined structure of the first incubation tray 210 and the second incubation tray 310 is compact, and the first incubation tray 210 and the second incubation tray 310 are driven and operated by the first drive component 220 and the second drive component 320 respectively. Compared with the traditional incubation device 10, the incubation device 10 of the present embodiment can avoid the overall size of each incubation tray being too large to affect the test speed while increasing the number of incubations in the incubation device 10.

[0041] The incubation device 10 of this embodiment can effectively increase the overall incubation test carrying capacity of the incubation device 10 by arranging the first incubation mechanism 200 and the second incubation mechanism 300 without increasing the overall size and weight of a single incubation tray. It has a compact structure and good use effect.

[0042] Specifically, see Figure 2 As shown, the containing structure 100 further includes an upper cover 500 , which is used to cover the first cavity 111 , the second driving assembly 320 is installed on the upper cover 500 , and the second driving assembly 320 is at least partially passed through the upper cover 500 and connected to the second incubation tray 310 .

[0043] In this embodiment, the insulation structure 130 includes an insulation chamber 131, an upper cover 500 and an insulation bottom plate 132. The insulation chamber 131 and the insulation bottom plate 132 are connected to enclose a second cavity 1311, and the upper cover 500 is detachably connected to the insulation chamber 131; when the second incubation mechanism 300 is needed to perform incubation operations, the second incubation mechanism 300 can be covered on the containing structure 100 together with the upper cover 500, and the second incubation tray 310 can be suspended in the containing groove 211 formed in the first incubation tray 210, so that the first incubation mechanism 200 and the second incubation mechanism 300 can be driven separately by their own driving components, the first incubation tray 210 and the second incubation tray 310 can rotate independently, and the overall structure is compact.

[0044] Specifically, the second drive assembly 320 includes a second drive member 321, a second transmission member 322 and a second drive shaft 323. The second drive member 321 is installed on the upper cover 500 and is located on the side of the upper cover 500 away from the first drive member 221. The second transmission member 322 is respectively connected to the second drive member 321 and the second drive shaft 323. The second drive shaft 323 is passed through the upper cover 500 and is connected to the second incubation tray 310.

[0045] With this arrangement, the second driving member 321 can change speed or torque through the second transmission member 322, and the second driving member 321 can be separated from the second driving shaft 323 to facilitate the arrangement of the second driving assembly 320; when the upper cover 500 is separated from the containing structure 100, the second driving shaft 323 can drive the second incubation tray 310 to be pulled out from the first incubation tray 210, and the second incubation mechanism 300 and the upper cover 500 are a modular overall structure, which is easy to separate.

[0046] Furthermore, the second drive assembly 320 also includes a positioning bearing 324, and one end of the second drive shaft 323 away from the second transmission member 322 is suspended in the first cavity 111, and the second drive shaft 323 is passed through the positioning bearing 324, and the positioning bearing 324 is arranged in the upper cover 500. The second drive shaft 323 is rotatably connected to the upper cover 500 through the positioning bearing 324, and the upper cover 500 is used to cover the first cavity 111, and the second incubation plate 310 is connected to the second drive shaft 323.

[0047] In this embodiment, the locating bearing 324 is preferably connected to the upper cover 500 using a double bearing, thereby improving the rotational stability of the second drive shaft 323 and the coaxiality between the second drive shaft 323 and the connecting shaft 430. Specifically, the double bearing can be two ball bearings or tapered bearings; of course, the locating bearing 324 can also be a single ball bearing, or more than two groups of bearings, which is not limited here.

[0048] In one embodiment, the second drive shaft 323 is penetrated with a connection hole 3231, and the base structure 400 further includes a connection shaft 430 and a positioning pin shaft 440, one end of the connection shaft 430 is connected to the seat body 410, and the other end of the connection shaft 430 is penetrated in the accommodating structure 100, and the positioning pin shaft 440 is penetrated in the connection hole 3231 from the side of the upper cover 500 away from the seat body 410 and is detachably connected to the connection shaft 430. After the positioning pin shaft 440 is connected to the second drive shaft 323 and the connection shaft 430, the positioning pin shaft 440 is relatively rotatably arranged with at least one of the second drive shaft 323 and the connection shaft 430.

[0049] In this embodiment, the second driving member 321 is arranged on the upper cover 500. When it is necessary to place the incubation sample in the first incubation tray 210 and the second incubation tray 310, the positioning pin 440 is first separated from the connecting shaft 430 to release the limiting function of the positioning pin 440 on the second driving shaft 323. Then, when the upper cover 500 is separated from the insulation chamber 131, the second incubation mechanism 300 can be driven to separate from the first incubation tray 210 together; after the second incubation mechanism 300 is combined with the first incubation mechanism 200, the positioning pin 440 is passed through the connecting hole 3231 and connected to the connecting shaft 430 to limit the axial movement of the second incubation tray 310 along the connecting shaft 430.

[0050] It should be noted that, after the locating pin 440 is connected to the second drive shaft 323 and the connecting shaft 430, the second drive shaft 323 can remain coaxial with the connecting shaft 430 under the positioning action of the locating pin 440. Of course, at this time, there can be at least three connection methods between the locating pin 440 and the second drive shaft 323 and the connecting shaft 430: In the first embodiment, the locating pin 440 and the second drive shaft 323 can be relatively fixed, for example, by means of threaded connection, interference fit, etc., and the locating pin 440 and the connecting shaft 430 are relatively rotatable, so that the locating pin 440 will not be in contact with the second drive shaft 323 and the connecting shaft 430; Embodiment 2, at this time, the positioning pin 440 and the second drive shaft 323 are relatively rotated, and when the positioning pin 440 is connected to the connecting shaft 430, it is relatively fixed with the connecting shaft 430, such as by threaded connection, interference fit, etc. At this time, when the second drive shaft 323 rotates, it will produce relative rotation with the positioning pin 440, and the positioning function can also be realized; Embodiment 3, the positioning pin 440 is only inserted into the connecting hole 3231 and inserted into the connecting shaft 430, and the three are coaxially arranged, and the positioning pin 440 can rotate relative to the second drive shaft 323 and the connecting shaft 430 at the same time. With this arrangement, the positioning pin 440 can not only limit the coaxiality of the second drive shaft 323 and the connecting shaft 430, but also avoid affecting the rotation function between the second drive shaft 323 and the connecting shaft 430, which is not limited here.

[0051] Specifically, the containing structure 100 includes a heating chamber 110, a heating plate 120 and a heat preservation structure 130. The heating chamber 110 is formed with a first cavity 111, and the heating plate 120 is used to heat the first cavity 111; the heat preservation structure 130 is formed with a second cavity, and the heating chamber 110 and the heating plate 120 are contained in the second cavity. By arranging the heating plate 120 at the bottom of the heating chamber 110, the heating plate 120 can control the temperature of the first incubation tray 210 and the second incubation tray 310 in the heating chamber 110. At the same time, since the heating plate 120 is arranged between the heating chamber 110 and the heat preservation chamber 131, the heat preservation chamber 131 can also keep the second cavity 1311 warm, so as to ensure the temperature control stability of the heating plate 120.

[0052] Further, see Figure 6 As shown, the containing structure 100 further includes a temperature control unit 140, which is electrically connected to the heating plate 120 and is used to obtain the temperature in the first cavity 111. Specifically, the temperature control unit 140 includes but is not limited to a temperature sensor and a temperature control switch.

[0053] In the present embodiment, the incubation device 10 further includes a control module, the control module signal is connected to the heating plate 120 and the temperature sensor, the temperature sensor obtains the temperature signal in the heating chamber 110 and transmits it to the control module, and the control module adjusts the temperature of the heating plate 120 according to the preset temperature to realize the automatic temperature control function of the heating plate 120. Specifically, the control module can be, but is not limited to, various PLCs (Programmable Logic Controller, full name Programmab le Logi c Controller), STM32 (STM32 microcontroller, a 32-bit microcontroller with ARM Cortex-M core), single-chip microcomputer, FPGA (Field Programmable Gate Array, full name Field Programmab le Gate Array), ARM (ARM processor, full name Advanced RISC Mach i ne), etc.

[0054] When a temperature switch is used, the temperature switch can directly realize physical changes according to the temperature in the heating chamber 110. For example, when the temperature in the heating chamber 110 exceeds the preset trip temperature of the temperature switch, the insulation structure 130 can be deformed and tripped to control the heating plate 120 to stop heating. When the temperature is lower than the preset trip temperature of the temperature switch, the temperature switch is reset and turned on, thereby realizing the temperature control function of the temperature switch. In some embodiments, the temperature control unit 140 and the temperature switch can work together to control the temperature of the heating plate 120. For example, the temperature switch can be used as a protection element. When the heating plate 120 exceeds the limit temperature, the heating plate 120 triggers the short circuit of the temperature switch, thereby improving the reliability of the heating plate 120.

[0056] In this embodiment, the first driving member 221 is located at the lower side of the containing structure 100 to make full use of the space between the containing structure 100 and the seat body 410. At the same time, the first driving member 221 and the first transmission member 222 can be kept away from the heating component 110 to avoid the heating component 110 affecting the operation of the first driving member 220. After the first driving shaft 223 is transmitted by the first transmission member 222, it extends from the bottom of the insulation structure 130 into the second cavity 1311 and is connected to the first incubation tray 210; the second driving member 321 is arranged at the top of the insulation structure 130, and the second driving shaft 323 is transmitted by the second transmission member 322 and then passes through the first cavity 111 and is connected to the second incubation tray 310. At this time, the second driving component 320 and the first driving component 220 are respectively located on the upper and lower sides of the first incubation tray 210, so that the overall structure of the incubation device 10 is compact and occupies a small space.

Through the induction cooperation between the first sensing disk 232 and the first sensor 231, the first sensor 231 can obtain the rotation position signal of the first sensing disk 232, and judge the signals such as the rotation position and rotation speed of the first incubation disk 210 through the control module; when the second driving shaft 323 is started, it can drive the second sensing disk 332 to rotate. Through the induction cooperation between the second sensing disk 332 and the second sensor 331, the second sensor 331 can obtain the rotation position signal of the second sensing disk 332, and judge the signals such as the rotation position and rotation speed of the second incubation disk 310 through the control module.

[0060] Specifically, a plurality of first sensing grooves 2321 are provided on the outer edge of the first sensing plate 232 , and the plurality of first sensing grooves 2321 are evenly arranged along the circumferential direction of the first sensing plate 232 ; a plurality of second sensing grooves 3321 are provided on the outer edge of the second sensing plate 332 , and the plurality of second sensing grooves 3321 are evenly arranged along the circumferential direction of the second sensing plate 332 .
