[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Figure 1 - Figure 7 As shown, this utility model provides a technical solution for a fecal sample preservation device for DNA extraction from golden snub-nosed monkeys. The device includes a box body 1, a circular cavity 3 inside the box body 1, a circular column 4 rotatably disposed inside the circular cavity 3, three placement cavities 5 arranged in a circumferential array on the outer side of the circular column 4, a through-hole 6 formed on one side of the circular cavity 3, a purification mechanism 2 for purifying the air inside the placement cavities 5 inside the box body 1, the outer wall of the circular column 4 contacting the inner wall of the circular cavity 3, and a sealing ring disposed between the circular column 4 and the inner wall of the circular cavity 3.

[0026] The preservation container 20 is conveniently placed by rotating the cylindrical column 4. The preservation container 20 is used to preserve the fecal sample of Sichuan golden monkey.

[0027] like Figure 5 As shown, the top and bottom of the circular cavity 3 are both formed with inner cavities 7. The top and bottom of the circular cavity 3 are both fixedly provided with partitions 8. The side of the bottom partition 8 away from the circular column 4 is fixedly connected to two ventilation hoods. The two ventilation hoods are fixedly connected to a connecting conduit 9. The purification mechanism 2 includes a purification chamber 201 formed in the box 1. The inner wall of the purification chamber 201 is fixedly connected to the bottom connecting conduit 9 with a ventilation conduit 10. The purification chamber 201 is provided with a linearly arrayed activated carbon filter plate 202. The side of the purification chamber 201 is fixedly connected to an exhaust port 203. An air intake fan 204 is installed inside the exhaust port 203. The side wall of the top inner cavity 7 is formed with a through-type air intake 11. The cavities of the exhaust port 203 and the air intake 11 are both provided with filter screens.

[0028] The top partition 8 has two through-hole openings. The openings and the placement chambers 5 are on the same circumferential track on the circular column 4. When one of the placement chambers 5 of the circular column 4 is facing the box opening 6, the other two placement chambers 5 of the circular column 4 are facing the bottom of the two openings respectively, and the two placement chambers 5 are also facing the top of the two vents respectively.

[0029] The air intake fan 204 is electrically connected to the power supply. The air intake fan 204 allows air from outside the housing 1 to enter the inner cavity 7 of the top layer through the air intake port 11. The airflow then enters the corresponding two placement chambers 5 through the top opening, carrying away the odors in the placement chambers 5. The odors then enter the purification chamber 201 through the connecting duct 9 and the ventilation duct 10, and are then filtered and purified by each activated carbon filter plate 202. The purified air is then discharged from the exhaust port 203.

[0030] like Figure 3 and Figure 7 As shown, a worm gear 12 and a worm 13 are rotatably mounted on the upper part of the top partition 8. The worm gear 12 and the worm 13 are meshed and connected to each other. A shaft is fixed between the axis of the worm gear 12 and the top of the circular column 4. A rocking plate 14 is fixedly mounted at the end of the worm 13. The rocking plate 14 is located on one side of the box body 1.

[0031] By rotating the rocker 14, the rocker 14 drives the worm gear 12 to rotate using the worm 13, and the worm gear 12 drives the cylindrical column 4 to rotate.

[0032] like Figure 6 As shown, the bottom of the worm gear 12 is fixedly connected to a fixing plate. The fixing plate has a positioning groove 15 on one side of each placement cavity 5. A pin groove is formed on the inner wall of the top inner cavity 7. A positioning rod 16 is slidably arranged in the pin groove. A spring is provided between one end of the positioning rod 16 and the inner wall of the pin groove. The other end of the positioning rod 16 is a rod head with a semi-circular structure. The rod head is adapted to the cavity of the positioning groove 15.

[0033] When the circular cylinder 4 is rotated, each placement cavity 5 on the circular cylinder 4 corresponds to the box opening 6 in sequence. The rod head of the positioning rod 16 will be inserted into the cavity of the corresponding positioning groove 15. In this way, the position of each placement cavity 5 is determined and the box opening 6 is aligned with the corresponding placement cavity 5. Since the rod head is not curved, the positioning rod 16 can increase the friction of the rotation of the circular cylinder 4 through the elastic force of the spring. The operator can complete the rotation of the circular cylinder 4 by manually rotating the worm gear 13 with a force greater than the elastic force of the spring.

[0034] like Figure 1 , Figure 2 and Figure 6 As shown, a sealing door 17 is rotatably installed on one side of the box body 1, and the sealing door 17 is adapted to the cavity opening of the box opening 6;

[0035] The sealing door 17 is used to close or open the circular cavity 3.

[0036] like Figure 7 As shown, two first placement racks 18 are fixedly connected to the inner wall of the placement cavity 5. Two sets of wire grooves are opened on both sides of the inner wall at the opening of the placement cavity 5. A second placement rack 19 is slidably arranged between the two wire grooves of the same set. A placement opening is formed between the second placement rack 19 and the first placement rack 18. A storage container 20 is placed in the cavity of the placement opening.

[0037] The first placement rack 18 and the second placement rack 19 are used together to ensure that the storage container 20 can be stably placed in the cavity of the placement chamber 5.

[0038] like Figure 4 As shown, two vents are opened on the upper part of the bottom partition 8, and two vent hoods are respectively set at the openings of the two vents. A grid plate is set at the opening of the vent.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
