However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1

[0033] Reference Figures 1 to 7 , which is the first embodiment of the present invention, provides a multifunctional microbial culture dish. The multifunctional microbial culture dish includes a main body assembly 100, including a culture dish body 101 and a sealing plug 102. The sealing plug 102 is arranged in the bottleneck of the culture dish body 101.

[0034] The sealing plug 102 is used to seal the culture dish body 101 , and the culture dish body 101 is used to culture anaerobic microorganisms.

[0035] The sampling assembly 200 is arranged in the culture dish body 101, including a sampling rod 201a arranged in the culture dish body 101, a sampling head 201b is fixed at the end of the sampling rod 201a, a positioning ring 201c is fixed on the surface of the sampling rod 201a, a sealing sleeve 201d is slidably connected to the surface of the sampling rod 201a, a fixing ring 201e is fixed on the surface of the sealing sleeve 201d, a sealing cover 201f is fixed on one side of the fixing ring 201e, a placement groove 102-1 is opened on the top of the sealing plug 102, and the port of the sealing sleeve 201d is located in the placement groove 102-1.

[0036] By inserting the sampling rod 201a into the culture dish body 101, anaerobic microorganisms are sampled through the sampling head 201b. When the sampling rod 201a is pulled, the sampling head 201b leaves the culture dish body 101. When the sampling head 201b enters the sealing sleeve 201d, the positioning ring 201c will push the inner top wall of the sealing sleeve 201d, so that the sealing sleeve 201d is away from the sealing plug 102. At this time, the sealing cover 201f can seal the opening of the sealing sleeve 201d, and the fixing ring 201e is used to fix the sealing cover 201f.

[0037] Specifically, the sampling assembly 200 further includes a sealing member 202 disposed in the sealing plug 102, including a driving shaft 202a sliding in the sealing plug 102, a connecting rod 202b fixed to the top of the driving shaft 202a, and a handle 202c fixed to the top of the connecting rod 202b.

[0038] By rotating the handle 202c, the connecting rod 202b can drive the driving shaft 202a to rotate, and by pulling the handle 202c, the driving shaft 202a can be driven to move up and down in the sealing plug 102.

[0039] Preferably, the seal 202 further includes a rotating seat 202d sliding on the surface of the drive shaft 202a, a limiting strip 202e is fixed in the rotating seat 202d, a sliding groove 202a-1 is opened on the surface of the drive shaft 202a, and the limiting strip 202e slides in the sliding groove 202a-1.

[0040] By setting the limiting strip 202e, the driving shaft 202a can drive the rotating seat 202d to rotate synchronously. When the driving shaft 202a moves up and down, the limiting strip 202e slides in the sliding groove 202a-1.

[0041] Preferably, a rocker arm 202f is fixed to one side of the rotating seat 202d, a sealing plate 202g is fixed to the end of the rocker arm 202f, a sampling hole 102-2 is opened at the bottom of the placement groove 102-1, and the sealing plate 202g is used to seal the sampling hole 102-2.

[0042] The rocker 202f is used to fix and support the sealing plate 202g. The sealing plate 202g slides in the placement groove 102-1 to seal the sampling hole 102-2.

[0043] Preferably, a positioning strip 202h is fixed to one side of the sealing plate 202g, a limiting groove 201d-1 is provided on the surface of the sealing sleeve 201d, and an outlet 201d-2 is provided on one side of the limiting groove 201d-1.

[0044] The positioning bar 202h is engaged in the limiting groove 201d-1, thereby limiting the sealing sleeve 201d, so that the sealing sleeve 201d will not be easily separated from the sealing plug 102. By rotating the sealing sleeve 201d, the outlet 201d-2 can be moved to the side of the positioning bar 202h. At this time, the sealing sleeve 201d can be pulled to make the positioning bar 202h slide out of the limiting groove 201d-1 from the outlet 201d-2, and the sealing sleeve 201d can be removed.

[0045] Preferably, a first spring 202i is fixed to one side of the rocker arm 202f, and the other end of the first spring 202i is fixed to the inner wall of the sealing plug 102.

[0046] The first spring 202i is in a stretched state. The reset tension of the first spring 202i causes the first spring 202i to pull the rocker 202f, thereby causing the rocker 202f to drive the sealing plate 202g to seal the sampling hole 102-2.

[0047] Example 2

[0048] Reference Figure 4 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment:

[0049] Preferably, the sampling assembly 200 also includes an isolation member 203, which is arranged in the sealing plug 102, including a drive ring 203a fixed to the surface of the drive shaft 202a, a second spring 203b is sleeved on the surface of the drive shaft 202a, and an isolation chamber 102-3 is provided in the sealing plug 102.

[0050] The second spring 203b is in a compressed state. The restoring elastic force of the second spring 203b can squeeze the drive ring 203a, so that the drive ring 203a drives the drive shaft 202a to move downward and reset. The second spring 203b and the drive ring 203a are both located in the isolation cavity 102-3.

[0051] Specifically, a support rod 203c is fixed on the surface of the driving shaft 202a, and an insertion rod 203d is fixed on the surface of the support rod 203c.

[0052] The support rod 203c is used to support the insertion rod 203d, so that when the driving shaft 202a rotates or moves up and down, it can drive the insertion rod 203d to move synchronously.

[0053] Specifically, an isolation plug 203e is slidably arranged on the surface of the insertion rod 203d, and a third spring 203f is sleeved on the surface of the insertion rod 203d.

[0054] The third spring 203f is in a compressed state, and is used to push the isolation plug 203e so that the isolation plug 203e is tightly attached to the inner bottom wall of the isolation cavity 102-3.

[0055] Preferably, an isolation hole 102 - 4 is opened at the bottom of the isolation cavity 102 - 3 , and the isolation plug 203 e is used to seal the isolation hole 102 - 4 .

[0056] The isolation hole 102-4 is used to separate the isolation cavity 102-3 and the culture chamber of the culture dish body 101. The sampling rod 201a can enter the culture chamber of the culture dish body 101 through the isolation hole 102-4. The isolation cavity 102-3 and the sealing sleeve 201d are filled with carbon dioxide gas, thereby preventing oxygen in the air from entering the isolation cavity 102-3 and the sealing sleeve 201d.

[0057] During use, when it is necessary to sample the anaerobic microorganisms in the culture dish body 101, the sealing cover 201f is first opened so that the end of the sealing sleeve 201d is tightly attached to the top of the sealing plate 202g. At this time, the handle 202c can be pulled upward to drive the drive shaft 202a to rise, so that the rod 203d drives the isolation plug 203e away from the isolation hole 102-4. At this time, the handle 202c is moved again to drive the drive shaft 202a to rotate, so that the drive shaft 202a drives the rotating seat 202d to rotate synchronously. The rotating seat 202d drives the sealing plate 202g to move synchronously through the rocker 202f, so that the sealing sleeve 201d port on the top of the sealing plate 202g falls into the placement groove 102-1 and is located at the top of the sampling hole 102-2. At this time, the positioning bar 202h enters the limiting groove 201d-1 through the outlet 201d-2. At this time, the sealing sleeve 201d is rotated so that the positioning bar 202h limits the sealing sleeve 201d, thereby stably connecting the sealing sleeve 201d and the sealing plug 102.

[0058] During the rotation of the drive shaft 202a, the drive shaft 202a drives the isolation plug 203e to move synchronously through the insertion rod 203d, so that the isolation plug 203e is away from the isolation hole 102-4. At this time, the sampling rod 201a can be moved, so that the sampling head 201b enters the culture dish body 101 through the sampling hole 102-2 and the isolation hole 102-4, thereby sampling anaerobic microorganisms and causing the anaerobic microorganisms to adhere to the surface of the sampling head 201b.

[0059] When sampling is completed, the sampling rod 201a is pulled to make the sampling head 201b leave the culture dish body 101. When the sampling head 201b enters the sealing sleeve 201d, the positioning ring 201c will push the inner top wall of the sealing sleeve 201d. At this time, the sealing sleeve 201d is rotated to move the outlet 201d-2 to the side of the positioning bar 202h. At this time, the sealing sleeve 201d can be pulled to make the positioning bar 202h slide out of the limiting groove 201d-1 from the outlet 201d-2. At this time, the sealing sleeve 201d can be removed, and the opening of the sealing sleeve 201d can be sealed by the sealing cover 201f, so that the anaerobic microbial sample is stored in the sealing sleeve 201d filled with carbon dioxide.

[0060] When the sealing sleeve 201d moves out of the placement groove 102-1, under the reset tension of the first spring 202i, the rocker arm 202f can drive the sealing plate 202g to seal the sampling hole 102-2, and at the same time drive the driving shaft 202a to rotate, so that the insertion rod 203d drives the isolation plug 203e to move above the isolation hole 102-4. Under the reset elastic force of the third spring 203f, the isolation plug 203e can seal the isolation hole 102-4.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
