Description

Technical Field

[0001] The utility model belongs to the technical field of microbial culture equipment, and particularly relates to a device for adjusting microbial culture conditions. Background Technique

[0002] Microbial culture refers to the process of enabling certain (species) of microorganisms to grow and reproduce under controlled environments through artificially prepared culture media and artificially created culture conditions (such as temperature, humidity, light, acidity and alkalinity, etc.). This process is the basis of microbiological research and application, and is widely used in fields such as medicine, agriculture, and environmental protection.

[0003] During the microbial culture process, the change of light conditions needs to be adjusted according to the growth stage of the microorganisms. It is mentioned in documents such as "The Influence of Light Intensity and Light Cycle on the Development of Gametophytes of Saccharina japonica". From the mycelial growth stage to the fruiting body development stage, the light requirement changes from none to some, and from weak to strong. Therefore, by reasonably controlling the light conditions, the culture effect of microorganisms can be optimized. Currently, during the microbial culture process, in order to ensure the light conditions, a light source is usually set inside the incubator. However, most of the existing light sources are fixed, which is not convenient for adjusting the irradiation area and irradiation intensity according to the growth cycle of the microorganisms, thus affecting the survival of the microorganisms. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model designs a device for adjusting microbial culture conditions, which can adjust the light area according to the growth cycle of the microorganisms while adjusting the light intensity, so that the light conditions meet the culture requirements of the microorganisms.

[0005] In order to achieve the above purpose, the utility model is realized through the following technical solutions:

[0006] A device for adjusting microbial culture conditions includes an incubator and a lighting device. A box door is installed in front of the incubator, and a temperature and humidity control component is installed on the back. The lighting device is arranged on the top of the incubator, and a baffle is arranged below the lighting device. The baffle is inserted into the slots opened on the front and rear sides of the installation shell. A slide rail is opened on the left side inside the installation shell and is connected to the slide seat arranged on the left side of the baffle. An adjusting rod is also arranged in the slide rail and is connected to the slide seat. The lighting device and the baffle are connected by a scissor lift arranged on the left side. One of the connecting rods at the bottom of the scissor lift is hinged to the top of the slide seat.

[0007] Two baffles are arranged oppositely, and the two baffles are respectively inserted into the slots on the front and rear sides of the installation shell.

[0008] Slide rails are opened on both the left and right sides inside the installation shell and are connected to the slide seats arranged on the left and right sides of the baffle. An adjusting rod is arranged in one of the slide rails and is connected to the slide seat, and a light shaft penetrates through the slide seat in the other slide rail.

[0009] The adjusting rod is provided as a lead screw with opposite thread directions at both ends with the center as the axis of symmetry. The front and rear ends of the lead screw are respectively threadedly connected to the sliding seats of the two shielding plates, and one end of the lead screw extends out of the installation housing and is connected to the driving motor.

[0010] The lighting device and the shielding plate are connected by two scissor lifts provided on the left and right sides. The two connecting rods at the bottom of the scissor lift are respectively hingedly connected to the connecting blocks at the tops of the two opposing sliding seats. The connecting blocks extend out of the top of the installation housing and are slidably connected in the through grooves opened at the top of the installation housing. The two connecting rods at the top of the scissor lift are respectively connected to the rotating shaft, and the rotating shaft is slidably connected in the sliding groove on the side wall of the lighting device.

[0011] The beneficial effects of the present utility model are:

[0012] Compared with the prior art, the present utility model installs a lighting device on the top of the incubator. A shielding plate is provided under the lighting device. Sliding seats are provided on the left and right sides of the shielding plate and are connected to the sliding rails of the installation housing. The shielding plate can be slid in the installation housing through the adjusting rod, so as to adjust the shielding area of the shielding plate against the lighting device, and thus adjust the irradiation area of the microorganisms in the incubator. At the same time, under the connection of the scissor lift between the lighting device and the shielding plate, during the process of the sliding seat moving to close or open the lighting device by the shielding plate, the scissor lift also drives the lighting device to rise or fall accordingly, adjusting the distance between the lighting device and the microorganisms, and thus controlling the light intensity. It can achieve adjusting to a suitable irradiation area and irradiation intensity at different microorganism culture stages. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Embodiment 1

[0023] In order to solve the problem that the irradiation light source for current microorganism culture is not convenient to adjust the irradiation area and intensity according to the growth cycle of microorganisms, thus affecting the survival of microorganisms.

[0024] Refer to Figures 1 to 5 As shown, a device for adjusting the culture conditions of microorganisms is proposed, including an incubator 1 and a lighting device 3. A door 101 of the incubator is installed in the front of the incubator 1. Through the opening and closing of the door 101, it is convenient to put in and take out the microorganism culture medium. A temperature and humidity control component 2 is installed on the back to adjust and control the temperature and humidity in the incubator 1.

[0025] The lighting device 3 is arranged on the top of the incubator 1. A lamp tube 301 capable of adjusting the light wavelength is installed inside the lighting device 3. Two opposite baffle plates 4 are arranged under the lamp tube 301. The baffle plates 4 are respectively inserted into the slots 501 opened on the front and back sides of the installation housing 5. When the two baffle plates 4 are in contact with each other, the lighting device 3 is completely closed. Slide rails 502 are opened on the left and right sides inside the installation housing 5 and are connected to the slide bases 401 arranged on the left and right sides of the baffle plates 4. An adjusting rod is arranged in one of the slide rails 502 and is connected to the slide base 401. An optical axis 7 is arranged in the other slide rail 502 and penetrates through the slide base 401. The adjusting rod is used to control the sliding of the slide base 401, and the optical axis 7 guides the sliding of the other slide base 401.

[0026] In this embodiment, the adjusting rod is set as a lead screw 6 with opposite thread directions at both ends centered on the axis of symmetry. The front and rear ends of the lead screw 6 are respectively threadedly connected to the slide bases 401 of the two baffle plates 4. One end of the lead screw 6 is connected to the inside of the installation housing 5 through a bearing 601, and the other end is also connected to the inside of the installation housing 5 through a bearing 601 and extends out of the installation housing 5 and is connected to a driving motor 602. The driving motor 602 is fixed on the installation housing 5.

[0027] Driving the lead screw 6 by the drive motor 602 can perform the opening and closing sliding of the two opposing shielding plates 4, thereby adjusting and controlling the irradiation area of the lighting device 3. And a control program can be introduced into the drive motor 602 as needed to automatically adjust the light conditions from the mycelium growth stage to the fruiting body development stage.

[0028] The lighting device 3 is connected to the shielding plate 4 by two scissor lifts 8 provided on the left and right sides. The scissor lift 8 is composed of two cross-linked connecting rods hinged in the middle. The two connecting rods at the bottom of the scissor lift 8 are respectively hinged to the connecting blocks 9 at the tops of the two opposing sliding seats 401. The connecting blocks 9 extend out of the top of the installation housing 5 and are slidably connected in the through groove 503 opened at the top of the installation housing 5. The two connecting rods at the top of the scissor lift 8 are respectively connected to the rotating shaft 10. The rotating shaft 10 is slidably connected in the chute 302 on the side wall of the lighting device 3.

[0029] While the shielding plate 4 slides, it drives the scissor lift 8 to rise and fall, thereby adjusting the distance between the lighting device 3 and the microorganism to control the light intensity.
