Description of the drawings:

fig. 1 is a schematic front view of the embodiment of the present invention;

FIG. 2 is a schematic view of the exploded view of FIG. 1;

fig. 3 is a schematic sectional view taken along line a-a in fig. 1.

The specific implementation mode is as follows:

the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description of the present invention, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

As shown in fig. 1 to 3, the utility model relates to a microorganism culture dish with ventilation, which comprises a circular dish body 1 and a circular dish cover 2 covering the upper end of the dish body 1, wherein the upper half part of the inner side wall of the dish cover 2 is provided with four ventilation holes 3 distributed circumferentially around the axis of the dish cover 2, so that the exchange of the gas inside and outside the culture dish is facilitated, and the ventilation function is realized; the air holes 3 are sealed by the air-permeable sealing film 4, and the air holes are sealed by the air-permeable sealing film after the bacteria cake is inoculated, so that the pollution probability is effectively reduced; the inside wall of ware lid 2 has connected firmly separation ring 5 in the below of bleeder vent 3, the bottom surface of separation ring 5 is located the top of 2 bottom surfaces of ware lid and is used for the top surface looks butt with the ware body 1, and the separation ring props up whole ware lid, greatly increased the inside space of culture dish, more is favorable to the growth of fungus thing.

In this embodiment, the left and right sides of every bleeder vent 3 is equipped with vertical support bar 6 of fixing at the ware lid inside wall respectively, the top surface of support bar 6 and the interior top surface looks butt of ware lid 2, the bottom surface of support bar 6 and the top surface looks butt of separation ring 5 utilize the support bar top to support between ware lid and separation ring, play the effect of strengthening, improve the support of separation ring, separate the effect. By arranging the separating ring, the height of the dish cover is 5mm higher than that of a common 9cm plastic dish cover when the dish cover is used.

In this embodiment, the air-permeable sealing film 4 is disposed on the outer side wall of the dish cover 2.

In this embodiment, the edge of the outer top surface of the dish cover 2 is fixedly connected with an anti-slip ring 7. Set up the antiskid circle at the outer top surface of ware lid for piling up that a plurality of culture dishes can be firm, practice thrift the space, a plurality of samples go on simultaneously, reduce the quantity of using artificial climate room and let in indoor gas and fumigant's quantity.

In this embodiment, in the use, this ventilative ware space is bigger more is favorable to the growth of fungus thing, and the design that the bleeder vent was laterally put makes the culture dish can pile up, and the guarantee has more been added to the joining of antiskid circle, and the process of no matter pouring the dish or the process of cultivateing all makes things convenient for a lot. The fungus cake is sealed after inoculation, the growth condition of the fungus can be observed at the early growth stage of the fungus which is most prone to pollution, and the problem of real-time observation at the later stage can be solved. After the bacterial cake is inoculated, the air holes are sealed by the air-permeable sealing film, so that the probability of pollution is reduced. And the increase of the air-permeable hole and the space is more beneficial to the accurate implementation of the gas experiment.

The utility model has the advantages that: the arrangement of the air holes facilitates the exchange of air inside and outside the culture dish: the air holes are positioned on the side wall of the heightened dish cover, so that the top end of the dish cover can be directly observed, and the dish cover can be sealed by a sealing film, so that the dish cover is not easy to pollute; due to the fact that the air holes are arranged on the side and the anti-slip ring is arranged on the side, the culture dish can be stacked, culture space is saved, a plurality of samples are carried out simultaneously, and the number of artificial climate chambers and the number of indoor air and fumigant introduced are reduced; the arrangement of the separating ring ensures the normal operation and convenient cleaning of the vent hole; simple processing, repeated use and reduced cost.

The utility model discloses if disclose or related to mutual fixed connection's spare part or structure, then, except that other the note, fixed connection can understand: a detachable fixed connection (for example using bolts or screws) is also understood as: non-detachable fixed connections (e.g. riveting, welding), but of course, fixed connections to each other may also be replaced by one-piece structures (e.g. manufactured integrally using a casting process) (unless it is obviously impossible to use an integral forming process).

In addition, the terms used in any aspect of the present disclosure as described above to indicate positional relationships or shapes include similar, analogous, or approximate states or shapes unless otherwise stated.

The utility model provides an arbitrary part both can be assembled by a plurality of solitary component parts and form, also can be the solitary part that the integrated into one piece technology was made.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
