[0018] A method for using a culture device for carnivorous crystal rotifers comprises the following steps:

[0019] S1: First, the top cover is rotated around the positioning seat and opened from the top of the housing. At this time, a specified number of glass slides are aligned with the second card slot opened inside the housing according to the number of Brachionus rotifers that need to be cultured. After the glass slides are placed, the light strip is turned on to illuminate the interior of the housing;

[0020] S2: Then, culture medium is added from the top of the shell until the culture medium completely covers the height of the glass slide. At this time, a certain number of square-shaped Brachionus rotifers are put into the shell, and an appropriate amount of Chlorella is added for feeding. After feeding, the top cover is reset, and the square-shaped Brachionus rotifers are attracted to feed between the glass slides through the light strip, prompting the square-shaped Brachionus rotifers to adhere to the surface of the glass slide. When the square-shaped Brachionus rotifers have reproduced to a sufficient number, a carnivorous crystal cyst rotifer is put in to start the cultivation of the carnivorous crystal cyst rotifers;

[0021] S3: Then, when it is necessary to clean the excrement, egg shells and food residues produced during the reproduction of the square-shaped Brachionus rotifer and the carnivorous crystal cyst rotifer, the handle on the top of the crossbar is manually grasped to drive the crossbar downward along the direction of the limit column. At this time, the first magnet and the second magnet on one side of the crossbar are separated from the magnetic block on one side of the culture chamber, and the rack on one side of the crossbar is simultaneously engaged with the first gear and the second gear for transmission. The rotation of the first gear and the second gear drives the second partition and the first partition to rotate. At this time, the food residues that fall on the main partition, the first partition and the top of the second partition slowly settle at the bottom of the culture chamber;

[0022] S4: When food residue and other impurities settle at the bottom of the culture chamber, the first handle is manually grasped and pulled upward to drive the crossbar upward until the first magnet and the second magnet are attracted to the magnetic block on one side of the culture chamber. The crossbar is fixed to one side of the culture chamber, and the rack drives the first gear and the second gear to reset, thereby driving the second partition to reset with the first partition. The culture chamber is divided into upper and lower parts by the second partition, the sealing strip, the first partition, and the main partition.

[0023] S5: Next, when it is necessary to clean the impurities deposited on the bottom of the main partition inside the culture chamber, the first slider is manually slid to drive the second block to separate from the first block. At this time, the blocking plate at the bottom of the first block is no longer restricted. After the culture chamber and the cleaning chamber are connected by pulling the blocking plate upward, the first connecting rod and the second connecting rod are manually rotated around the adapter block from the inside of the first slot to form a push rod. The first connecting rod and the second connecting rod are manually grasped to push the second slider along the direction of the slide bar. During the movement of the second slider, the second slider pushes the impurities at the bottom of the culture chamber from one side of the second slider to the inside of the cleaning chamber.

[0024] S6: After the impurities are pushed into the cleaning chamber, the first connecting rod, the second connecting rod, and the second slider are reset, and then the blocking plate is moved downward to block the culture chamber and the cleaning chamber again. At this time, the first slider is manually moved to drive the second clamping block to engage with one side of the first clamping block, thereby fixing the first clamping block and the blocking plate;

[0025] S7: Finally, connect the water pipe to the water inlet pipe, then pull out the soft plug, and remove the impurities inside the cleaning chamber by injecting water into the cleaning chamber.

[0026] Compared with the prior art, the present invention has at least the following beneficial effects:

[0027] 1. A culture device and method for carnivorous crystal rotifers. By setting a main partition, when it is necessary to clean the food residue and rotifer excrement inside the culture bin, the main partition can be opened to allow the food residue inside the culture bin to naturally settle to the bottom of the culture bin, and then the rotifers on the top of the culture bin and the excrement settled at the bottom are separated by an isolation mechanism. The rotifers do not need to be fished out for cleaning, thereby reducing the impact of the external environment on the rotifers.

[0028] 2. A culture device and method for carnivorous crystal rotifers. By setting a baffle plate, the excrement at the bottom of the culture chamber is pushed into the interior of the cleaning chamber by pushing the second slider, and the excrement can be collected and cleaned inside the cleaning chamber. Under normal circumstances, the culture chamber and the cleaning chamber are separated by the baffle plate. Compared with the method of pouring out all the culture solution and then cultivating rotifers, this cleaning method is fast and simple to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] What needs to be further explained is that: when the culture chamber 1 is culturing carnivorous crystal rotifers, the culture medium needs to be injected into the interior of the culture chamber 1, but when the cleaning mechanism 3 cleans the interior of the culture chamber 1, there is no need to pour out the culture medium inside the culture chamber 1 before cleaning. The isolation mechanism 2 can separate the sediment at the bottom of the culture chamber 1 from the carnivorous crystal rotifers at the top, and then clean them.

[0046] like Figure 3 、 Figure 4 and Figure 5 As shown, the isolation mechanism 2 includes a cross bar 201, a first handle 202, a first magnet 203, a second magnet 204, a limiting column 205, a positioning plate 206 and a rack 207. The cross bar 201 is movably connected to one side of the culture chamber 1, the top of the cross bar 201 is fixedly connected to the first handle 202, one side of the cross bar 201 is fixedly installed with the first magnet 203, the other side of the cross bar 201 is fixedly installed with the second magnet 204, one side of the cross bar 201 is movably connected to the limiting column 205, the limiting column 205 is fixedly connected to the top of the positioning plate 206, and the bottom of the cross bar 201 is fixedly connected to the rack 207.

[0047] The isolation mechanism 2 also includes a first gear 208, a first rotating shaft 209, a first partition 210, a sealing strip 211, a second partition 212, a second gear 213, a second rotating shaft 214 and a main partition 215. The first gear 208 is meshed and transmitted on one side of the rack 207. One side of the first gear 208 is fixedly connected to the first rotating shaft 209. One side of the first rotating shaft 209 is fixedly connected to the first partition 210. One side of the first partition 210 is fixedly connected to the sealing strip 211. One side of the sealing strip 211 is movably connected to the second partition 212. One side of the second partition 212 is fixedly connected to the second rotating shaft 214. The second rotating shaft 214 is fixedly connected to one side of the second gear 213. The second gear 213 is meshed and transmitted on one side of the rack 207. The main partition 215 is fixedly installed inside the culture chamber 1.

[0048] The first rotating shaft 209 is movably installed inside the culture chamber 1, and the culture chamber 1 has a hole at the corresponding position of the first rotating shaft 209. The second rotating shaft 214 is movably installed inside the culture chamber 1, and the culture chamber 1 has a hole at the corresponding position of the second rotating shaft 214. The first partition 210 is movably connected to one side of the main partition 215, and the second partition 212 is movably connected to the other side of the main partition 215.

[0049] The first magnet 203 and the second magnet 204 are movably connected to one side of the culture chamber 1 , and the culture chamber 1 is provided with magnetic blocks with opposite magnetic poles at corresponding positions of the first magnet 203 and the second magnet 204 , and the positioning plate 206 is fixedly installed on one side of the culture chamber 1 .

[0050] What needs to be further explained is that: in normal state, the first magnet 203 and the second magnet 204 on one side of the cross bar 201 are adsorbed on the magnetic block at the corresponding position on one side of the culture chamber 1 under the action of magnetic force, thereby fixing the cross bar 201 on one side of the culture chamber 1. When it is necessary to separate and clean the rotifers inside the culture chamber 1 and the excrement deposited at the bottom of the culture chamber 1, the cross bar 201 is manually grasped by the handle on the top of the cross bar 201 to drive the cross bar 201 to move downward along the direction of the limit column 205. At this time, the first magnet 203 and the second magnet 204 on one side of the cross bar 201 are separated from the magnetic block on one side of the culture chamber 1. , and the rack 207 on one side of the cross bar 201 is engaged with the first gear 208 and the second gear 213 at the same time, and the rotation of the first gear 208 and the second gear 213 drives the second partition 212 and the first partition 210 to rotate. At this time, the food residues that fall on the main partition 215, the first partition 210 and the top of the second partition 212 slowly settle at the bottom of the culture chamber 1. Finally, the cross bar 201 is manually moved to drive the first magnet 203 and the second magnet 204 to be adsorbed with the magnetic block on one side of the culture chamber 1 again to complete the separation of the inside of the culture chamber 1 by the main partition 215.

[0051] like Figure 6 、 Figure 7 and Figure 8 As shown, the cleaning mechanism 3 includes a cleaning chamber 301, a soft plug 302, a baffle 303, a water inlet pipe 304, a slide 305, a first block 306, a second block 307, a first slider 308 and a slide rail 309. The cleaning chamber 301 is fixedly installed on one side of the culture chamber 1, and the soft plug 302 is movably installed on one side of the cleaning chamber 301. The baffle 303 is movably connected to one side of the cleaning chamber 301. The water inlet pipe 304 is provided on the other side of the cleaning chamber 301. The slide 305 is fixedly connected to one side of the cleaning chamber 301. The top of the baffle 303 is fixedly connected to the first block 306. One side of the first block 306 is movably connected to the second block 307. One side of the second block 307 is fixedly connected to the first slider 308. The first slider 308 is movably connected to the top of the slide rail 309. The slide rail 309 is fixedly installed on the top of the cleaning chamber 301.

[0052] The cleaning mechanism 3 also includes a second slider 310, a first slot 311, a limiting slot 312, a transfer block 313, a first connecting rod 314 and a second connecting rod 315. The second slider 310 is movably connected to one side of the slide bar 305. A first slot 311 is provided on one side of the second slider 310. Limiting slots 312 are provided on both sides of the second slider 310. A transfer block 313 is fixedly installed inside the first slot 311. One side of the transfer block 313 is movably connected to the first connecting rod 314, and the other side of the transfer block 313 is movably connected to the second connecting rod 315.

[0053] The cleaning chamber 301 is connected to the culture chamber 1 , and the blocking plate 303 is movably connected between the cleaning chamber 301 and the culture chamber 1 . A sealing strip is provided at the bottom of the blocking plate 303 .

[0054] The shape of the second slider 310 is the same as the shape of the cavity opened inside the cleaning chamber 301 . The length of the first connecting rod 314 and the second connecting rod 315 is longer than the width of the culture chamber 1 . The first connecting rod 314 and the second connecting rod 315 are movably connected inside the first slot 311 .

[0055] The second block 307 is disengaged from the first block 306 by manually sliding the first slider 308. At this time, the blocking plate 303 at the bottom of the first block 306 is no longer restricted. After the blocking plate 303 is pulled upward to connect the culture chamber 1 with the cleaning chamber 301, the first connecting rod 314 and the second connecting rod 315 are manually rotated around the adapter block 313 from the inside of the first slot 311 to form a push rod. The first connecting rod 314 and the second connecting rod 315 are manually grasped to push the second slider 310 along the direction of the slide bar 305. During the movement of the second slider 310, the second slider 310 pushes the impurities at the bottom of the culture chamber 1 from one side of the second slider 310 to the inside of the cleaning chamber 301. Finally, the excrement inside the cleaning chamber 301 is cleaned after being connected to the water pipe through the water inlet pipe 304.

[0056] like Figure 9 and Figure 10As shown, the cultivation mechanism 4 includes a shell 401, a second handle 402, a positioning seat 403, a top cover 404, a light strip 405, a second card slot 406 and a glass slide 407. The shell 401 is movably connected to the interior of the cultivation chamber 1. The second handle 402 is fixedly connected to one side of the shell 401, the positioning seat 403 is fixedly connected to the top of the shell 401, and the top cover 404 is movably connected to one side of the positioning seat 403. The bottom of the top cover 404 is provided with a light strip 405. A second card slot 406 is provided inside the shell 401, and a glass slide (407) is movably connected to one side of the second card slot (406). A rectangular groove is provided on one side of the glass slide 407. The top cover 404 is movably connected to the top of the shell 401, and the shell 401 is provided on the top of the main partition 215.

[0057] What needs to be further explained is that when it is necessary to add chlorella to feed the square-brachius rotifers, the top cover 404 is opened by rotating around the positioning seat 403, and then an appropriate amount of chlorella is put into the interior of the shell 401. When the square-brachius rotifers inside the shell 401 have multiplied to an appropriate number, a carnivorous crystal cyst rotifer is put into the interior of the shell 401, and the carnivorous crystal cyst rotifers inside the shell 401 are observed through the transparent culture chamber 1 and the shell 401. In addition, the square-brachius rotifers and the crystal cyst rotifers are both phototactic. Before the sediment and food residues need to be cleaned, in order to avoid the two types of rotifers being cleaned together with the sediment, it is necessary to turn on the light strip 405 to attract the rotifers to adsorb on the glass slide 407. Since the light strip 405 is located directly below the top cover 404, the rotifers will move upward along the glass slide 407, thereby reducing the possibility of the rotifers being cleaned at the same time when cleaning the residue.

[0058] A method for using a culture device for carnivorous crystal rotifers comprises the following steps:

[0059] S1: First, the top cover 404 is rotated around the positioning seat 403 and the top cover 404 is opened from the top of the housing 401. At this time, a specified number of glass slides 407 are aligned with the second card slots 406 opened inside the housing 401 according to the number of Brachionus square rotifers to be cultured. After the glass slides 407 are placed, the light strip 405 is turned on to illuminate the interior of the housing 401;

[0060] S2: Then, culture solution is added from the top of the housing 401 until the culture solution completely covers the height of the glass slide 407. At this time, a certain number of Brachionus squarrosus rotifers are put into the interior of the housing 401, and an appropriate amount of Chlorella vulgaris is added for feeding. After feeding, the top cover 404 is reset, and the Brachionus squarrosus rotifers are attracted to feed between the glass slides 407 through the light strip 405, so that the Brachionus squarrosus rotifers are adsorbed on the surface of the glass slide 407. When the Brachionus squarrosus rotifers have reproduced to a sufficient number, a carnivorous crystal cyst rotifer is put in to start the cultivation of the carnivorous crystal cyst rotifers;

[0061] S3: Then, when it is necessary to clean the excrement, egg shells and food residues produced during the reproduction of the square-shaped Brachionus rotifer and the carnivorous crystal cyst rotifer, the handle on the top of the cross bar 201 is manually grasped to drive the cross bar 201 downward along the direction of the limit column 205. At this time, the first magnet 203 and the second magnet 204 on one side of the cross bar 201 are separated from the magnetic block on one side of the culture chamber 1, and the rack 207 on one side of the cross bar 201 is simultaneously engaged with the first gear 208 and the second gear 213 for transmission. The rotation of the first gear 208 and the second gear 213 drives the second partition 212 and the first partition 210 to rotate. At this time, the food residues that fall on the top of the main partition 215, the first partition 210 and the second partition 212 are slowly settled at the bottom of the culture chamber 1;

[0062] S4: When food residues and other impurities settle at the bottom of the culture chamber 1, the first handle 202 is manually grasped and pulled upward to drive the crossbar 201 upward until the first magnet 203 and the second magnet 204 are attracted to the magnetic block on one side of the culture chamber 1. The crossbar 201 is fixed to one side of the culture chamber 1.

A method for using the culture device for carnivorous crystal rotifer according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: First, the top cover (404) is rotated around the positioning seat (403) and the top cover (404) is opened from the top of the housing (401). At this time, a specified number of glass slides (407) are aligned with the second card slots (406) opened inside the housing (401) and placed according to the number of Brachionus quadratus rotifers that need to be cultured. After the glass slides (407) are placed, the light strip (405) is turned on to illuminate the inside of the housing (401); S2: Then, culture solution is added from the top of the housing (401) until the culture solution completely covers the height of the glass slide (407). At this time, a certain number of square-shaped Brachionus rotifers are put into the housing (401), and an appropriate amount of Chlorella is added for feeding. After the feeding is completed, the top cover (404) is reset, and the square-shaped Brachionus rotifers are attracted to feed between the glass slides (407) through the light strip (405), so that the square-shaped Brachionus rotifers are adsorbed on the surface of the glass slide (407). When the square-shaped Brachionus rotifers have reproduced to a sufficient number, a carnivorous crystal cyst rotifer is put in to start the cultivation of the carnivorous crystal cyst rotifers; S3: Then, when it is necessary to clean the excrement, egg shells and food residues generated during the reproduction of the square-brachius rotifer and the carnivorous crystal cyst rotifer, the handle on the top of the cross bar (201) is manually grasped to drive the cross bar (201) to move downward along the direction of the limit column (205). At this time, the first magnet (203) and the second magnet (204) on one side of the cross bar (201) are separated from the magnetic block on one side of the culture bin (1), and the rack (207) on one side of the cross bar (201) is simultaneously meshed with the first gear (208) and the second gear (213) for transmission. The rotation of the first gear (208) and the second gear (213) drives the second partition (212) and the first partition (210) to rotate. At this time, the food residues that fall on the top of the main partition (215), the first partition (210) and the second partition (212) slowly settle at the bottom of the culture bin (1); S4: Then, when food residues and other impurities are deposited at the bottom of the culture chamber (1), the first handle (202) is manually grasped and pulled upward to drive the cross bar (201) to move upward until the first magnet (203) and the second magnet (204) are adsorbed on the magnetic block on one side of the culture chamber (1), and the cross bar (201) is fixed on one side of the culture chamber (1). At the same time, the rack (207) drives the first gear (208) and the second gear (213) to reset, thereby driving the second partition (212) and the first partition (210) to reset, and the culture chamber (1) is separated into two upper and lower parts by the second partition (212), the sealing strip (211), the first partition (210) and the main partition (215); S5: Next, when it is necessary to clean the impurities deposited at the bottom of the main partition (215) inside the culture bin (1), the first slider (308) is manually slid to drive the second block (307) to separate from the first block (306). At this time, the blocking plate (303) at the bottom of the first block (306) is no longer restricted. After the blocking plate (303) is pulled upward to connect the culture bin (1) with the cleaning bin (301), the first connecting rod (314) and the second connecting rod (315) are manually rotated around the adapter block (313) from the inside of the first slot (311) to form a push rod. The first connecting rod (314) and the second connecting rod (315) are manually grasped to push the second slider (310) to move along the direction of the slider (305). During the movement of the second slider (310), the second slider (310) pushes the impurities at the bottom of the culture bin (1) from one side of the second slider (310) to the inside of the cleaning bin (301); S6: After the impurities are pushed into the interior of the cleaning chamber (301), the first connecting rod (314), the second connecting rod (315) and the second slider (310) are reset, and then the blocking plate (303) is moved downward to block the culture chamber (1) and the cleaning chamber (301) again. At this time, the first slider (308) is manually moved to drive the second clamping block (307) to clamp onto one side of the first clamping block (306), thereby fixing the first clamping block (306) and the blocking plate (303); S7: Finally, connect the water pipe to the water inlet pipe (304), then pull out the soft plug (302), and remove the impurities inside the cleaning chamber (301) by injecting water into the cleaning chamber (301).
