[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.
[0029] like Figure 1 As shown, this embodiment proposes a bacterial culture dish capable of maintaining activity, which mainly includes a dish body 1 and a dish cover 2. The dish cover 2 is detachably connected to the dish body 1, making it easier to open and close the bacterial culture dish and more convenient to operate. An oxygen supply structure 3 is provided on the dish cover 2, and the oxygen supply structure 3 includes an oxygen supply body 31 and a connecting hole 32. An oxygen supply channel 311 is provided inside the oxygen supply body 31. The oxygen supply channel 311 can connect the inside and outside of the dish body 1, so that external oxygen can enter the inside of the dish body 1 through the oxygen supply channel 311, and continuously supply oxygen to the inside of the dish body 1, thereby ensuring the activity of the bacterial strains inside the dish body 1.
[0030] like Figure 2-3 As shown, the connection hole 32 passes through the dish cover 2, the oxygen supply body 31 is slidably connected to the connection hole 32, and the opening of the oxygen supply channel 311 connecting the inside and outside of the dish body 1 is located on the side of the oxygen supply body 31 close to the connection hole 32, that is, the hole wall of the connection hole 32 will block the oxygen supply channel 311. When the hole wall of the connection hole 32 blocks the oxygen supply channel 311, external oxygen cannot enter the inside of the dish body 1 through the oxygen supply channel 311; when it is necessary for external oxygen to enter the inside of the dish body 1 through the oxygen supply channel 311, it can be By sliding the oxygen supply body 31, the oxygen supply channel 311 is separated from the hole wall of the connecting hole 32, and then connected to the inside and outside of the dish body 1, so that external oxygen can enter the inside of the dish body 1 through the oxygen supply channel 311, thereby realizing the oxygen supply work inside the dish body 1. Moreover, this oxygen supply work is manually controlled, which makes it more convenient for the staff to decide whether the oxygen supply body 31 supplies oxygen according to the demand of the bacteria inside the dish body 1, making this embodiment more practical, and can deal with both bacteria that require a large amount of oxygen supply and bacteria that do not require a large amount of oxygen supply.
[0031] A filter 312 and a one-way valve 313 are provided in the oxygen supply channel 311. The filter 312 is used to filter the air to prevent external pollutants from entering the dish body 1 along the oxygen supply channel 311 and causing adverse effects on the bacterial culture. The one-way valve 313 can prevent the nutrients in the dish body 1 that provide nutrition for the bacteria from flowing back along the oxygen supply channel 311 and affecting the normal growth of the bacteria. At the same time, a sealing ring 4 is provided between the connecting hole 32 and the oxygen supply body 31 to prevent the unfiltered external gas from entering the dish body 1 along the sliding gap between the oxygen supply body 31 and the connecting hole 32 during the sliding process of the oxygen supply body 31 and causing adverse effects on the bacterial culture. The three cooperate with each other to fully ensure the safety and reliability of the cultivation process implemented in this embodiment.
[0032] The filter 312 in this embodiment is preferably a HEPA filter, which can effectively capture tiny particles such as dust, mold, and viruses in the air, ensuring the purity of the air entering the dish body 1 after being filtered by the oxygen supply structure 3.
[0033] The longitudinal section of the oxygen supply body 31 is a horizontal "H"-shaped structure, and a limiting ring 321 is provided in the connecting hole 32. The oxygen supply body 31 is slidingly connected to the limiting ring 321, that is, the movement distance of the oxygen supply body 31 is limited by the mutual cooperation between the limiting ring 321 and the oxygen supply body 31, and the oxygen supply body 31 is prevented from being separated from the connecting hole 32, thereby ensuring the integrity and stability of the overall structure of this embodiment; the sealing ring 4 is located between the limiting ring 321 and the oxygen supply body 31. Compared with laying the sealing ring 4 along the entire surface of the hole wall of the connecting hole 32, laying the sealing ring 4 only on the limiting ring 321 can also play a sealing role. At the same time, the volume of the sealing ring 4 used is relatively small, saving a certain economic cost.
[0034] At the same time, because the oxygen supplier 31 will be embedded in the connecting hole 32 due to the action of gravity when there is no external force intervention, in this case, it is difficult for the staff to slide the oxygen supplier 31, so a lifting handle 6 is provided on the oxygen supplier 31 for easy pulling of the oxygen supplier 31, and the lifting handle 6 is integrally formed with the oxygen supplier 31 to ensure the reliability of the connection relationship between the lifting handle 6 and the oxygen supplier 31, and prevent the lifting handle 6 from being separated from the oxygen supplier 31 when the staff pulls up the lifting handle 6, thereby ensuring the firmness and reliability of the overall structure of this embodiment.
[0035] like Figure 1 , Figure 7 As shown, a fixed support rod 7 is provided between the oxygen supply body 31 and the dish cover 2 in this embodiment. The fixed support rod 7 is detachably connected between the oxygen supply body 31 and the dish cover 2. The fixed support rod 7 fixes the oxygen supply body 31 by simultaneously abutting against the lifting handle 6 and the dish cover 2 to prevent the oxygen supply body 31 from being reset due to the influence of gravity, so that this embodiment can maintain a continuous oxygen supply state.
[0036] A mounting key slot is provided on the dish cover 2, and the fixed support rod 7 can slide in the mounting key slot. After sliding to the limit distance, the fixed support rod 7 is in two situations: the lowest point or the highest point of its top structure corresponds to the lifting handle 6. When the lowest point of the top structure of the fixed support rod corresponds to the lifting handle 6, the fixed support rod 7 can move upward, and the fixed support rod 7 after moving upward will be disengaged from the mounting key slot, so that the fixed support rod 7 can be moved out of the lifting handle 6 by rotating the fixed support rod 7 again, thereby realizing the disassembly of the fixed support rod 7 between the oxygen supplier 31 and the dish cover 2; the installation workflow of the fixed support rod 7 is opposite to the disassembly workflow, and the specific installation process will not be repeated in this embodiment.
[0037] like Figure 3-4 As shown, the oxygen supply channel 311 in this embodiment includes an air inlet 3111 and an oxygen supply duct 3112. The air inlet 3111 is located above the oxygen supply duct 3112, and the filter 312 is located between the air inlet 3111 and the oxygen supply duct 3112, so that the air entering the oxygen supply duct 3112 is filtered by the filter 312, which is clean and hygienic, and is unlikely to have an adverse effect on the bacterial culture inside the dish body 1. The one-way valve 313 is located below the filter 312 to achieve one-way delivery of the filtered air, and the one-way valve 313 can effectively prevent the internal nutrients of the dish body 1 from overflowing, thereby ensuring the bacterial culture efficiency.
[0038] like Figure 5-6 As shown, in the present embodiment, a number of air inlets 3111 are provided, and the number of air inlets 3111 is increased to ensure that enough air can enter. In the present embodiment, oxygen is supplied to the dish body 1 through the oxygen supply structure 3, so as to ensure the oxygen supply efficiency of the oxygen supply structure 3; and each air inlet 3111 is connected with the oxygen supply duct 3112, that is, each air inlet duct 3111 is distributed in the form of a circular array with the oxygen supply duct 3112 as the center, avoiding the need to additionally design an oxygen supply duct 3112 that matches each air inlet duct 3111 one by one, so as to facilitate the disinfection work of the present embodiment at a later stage; the oxygen supply duct 3112 and each air inlet duct 3111 are in a "T"-shaped structure, that is, the air inlet duct 3111 itself is horizontally placed and runs through the interior of the oxygen supply body 31, so as to facilitate its receiving and guiding of wind flow in all directions into the oxygen supply channel 311, thereby improving the oxygen supply efficiency of the oxygen supply structure 3.
[0039] At the same time, considering that the filter inlet and filter outlet of the filter 312 are limited, Figure 4 As shown, the filter 312 in this embodiment is located at one end of the oxygen supply duct 3112 close to each air inlet duct 3111, so that the filter 312 can receive the airflow and air in each air inlet duct 3111, thereby avoiding the filter 312 itself blocking the air inlet duct 3111, thereby affecting the oxygen supply efficiency of the oxygen supply structure 3.
[0040] like Figure 6As shown, an auxiliary drainage body 5 is provided in the oxygen supply channel 311 in the present embodiment. The auxiliary drainage body 5 is located above the filter 312 and is fixedly connected to one end of each air inlet 3111 away from the oxygen supply duct 3112. Since the air inlet ducts 3111 are interlaced at horizontal points of the filter 312, fixing the auxiliary drainage body 5 here can simultaneously guide the airflow and air in each air inlet duct 3111; and the longitudinal section of the auxiliary drainage body 5 is an inverted conical structure, so that the airflow and air in each air inlet duct 3111 flow downward along the conical surface structure of the auxiliary drainage body 5 and enter the filter 312; at the same time, due to the existence of the auxiliary drainage body 5 itself, it can play a certain role in blocking the airflow, and can avoid the phenomenon of gas convection in the oxygen supply channel 311, thereby preventing gas convection from affecting the oxygen supply efficiency of the oxygen supply structure 3.
[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
