Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection technology, specifically to a biochemical incubator used for detection. Background Technology
[0002] A biochemical incubator is a laboratory device used in fields such as biology, chemistry, and medicine. It is mainly used to provide a stable temperature, humidity, light, or gaseous environment (such as CO2 concentration) for experiments such as microbial culture, cell culture, seed germination, and enzyme reactions. Its core function is to simulate the ideal state required by biological or chemical reactions by precisely controlling environmental conditions, thereby ensuring the reliability and repeatability of experiments. A biochemical incubator is usually composed of a chamber for containing culture media and cultures, as well as environmental control components. The experimental environmental data can be controlled through the environmental control components, thereby rapidly and stably cultivating the required cultures within the incubator.
[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: When culturing food microorganisms on thicker culture media, existing biochemical incubators require frequent addition of water to maintain the humidity of the culture medium during the culturing process. However, existing biochemical incubators add distilled water from the top of the incubator. When adding water, the upper surface of the culture medium is often wetted first, while the lower part of the culture medium is difficult to wet quickly. Therefore, when using thicker culture media for microbial culturing, errors can easily occur due to the humidity difference between the upper and lower parts of the culture medium. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a biochemical incubator for detection that offers uniform water addition and minimal error.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a biochemical incubator for detection, comprising a main unit and a sealing door that is movable and snaps onto the front of the main unit. The main unit includes a control base and a heat-insulating shell disposed on the top surface of the control base. A culture tray is detachably installed on the inner wall of the heat-insulating shell. An upper water supply pipe is provided through the heat-insulating shell above the culture tray. A lower water supply pipe is provided through one side of the heat-insulating shell and extends into the heat-insulating shell. The top end of the lower water supply pipe is detachably inserted into the bottom surface of the culture tray.
[0006] A further improvement is that the sealed door is also equipped with an observation panel made of transparent material.
[0007] A further improvement is that a support block is provided at the bottom of the host unit.
[0008] A further improvement is that a control board is embedded in the outer surface of the control base.
[0009] A further improvement is that several electric heating tubes are fixedly installed on the inner wall of the heat insulation shell.
[0010] A further improvement is that several exhaust fans are installed on the inner wall of the heat insulation shell.
[0011] A further improvement is that the lower water supply pipe includes a horizontal water pipe that penetrates one side of the heat insulation shell and extends into the heat insulation shell, and an input pipe that is fixedly installed on the horizontal water pipe and whose top end can be detachably inserted into the bottom of the culture tray. A leak-proof pipe is embedded in the inner wall of the top end of the input pipe.
[0012] A further improvement is that a connecting pipe is provided at the end of the horizontal water pipe located outside the heat insulation shell.
[0013] A further improvement is that the leak-proof pipe includes an output pipe body embedded in the inner wall of the top of the input pipe and a ramp integrally formed on the top of the output pipe body. A frustum-shaped sealing block is attached to the ramp, and a sealing plate that can cover the top surface of the pipe body is provided on the top surface of the sealing block.
[0014] A further improvement is that the bottom surface of the sealing block is integrally formed with a square extension block.
[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When this utility model is used, water can be supplied to the culture tray simultaneously through the upper water supply pipe and the lower water supply pipe. In the process of water supply, the upper and lower surfaces of the culture medium can be wetted at the same time, which accelerates the water absorption efficiency of the culture medium. At the same time, the upper and lower surfaces of the culture medium can maintain the same level of moisture after water supply. Furthermore, after water supply, water can be prevented from leaking out from the lower water supply pipe through the leak-proof pipe, thereby effectively preventing errors caused by inconsistent humidity on the upper and lower surfaces of the culture medium.

[0021] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0022] See Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: a biochemical incubator for detection, including a main unit 1 and a sealing door 2 that is movable and engages with the front of the main unit 1. The main unit 1 includes a control base 11 and a heat-insulating shell 12 disposed on the top surface of the control base 11. A culture tray 13 is detachably installed on the inner wall of the heat-insulating shell 12. An upper water supply pipe 15 is provided through the heat-insulating shell 12 above the culture tray 13. A lower water supply pipe 14 is provided through one side of the heat-insulating shell 12 and extends into the heat-insulating shell 12. The lower water supply pipe 14 includes a part that penetrates one side of the heat-insulating shell 12 and extends into the heat-insulating shell 12. The outer casing 12 contains a horizontal water pipe 141 and an input pipe 143 fixedly installed on the horizontal water pipe 141 with its top end detachably inserted into the bottom surface of the culture tray 13. A leak-proof pipe 144 is embedded in the inner wall of the top end of the input pipe 143. The leak-proof pipe 144 includes an output pipe body 21 embedded in the inner wall of the top end of the input pipe 143 and a ramp 23 integrally formed on the top end of the output pipe body 21. A frustum-shaped sealing block 24 is attached to the ramp 23, and a sealing plate 25 covering the top surface of the pipe body 21 is provided on the top surface of the sealing block 24. The top end of the lower water pipe 14 is detachably inserted into the bottom surface of the culture tray 13. In use, the culture... The substrate is placed in the culture dish 13, and distilled water is supplied to the culture dish 13 from above through the upper water supply pipe 15 and from below through the lower water supply pipe 14. The lower water supply pipe 14 is connected to an external distilled water source and supplies distilled water into the horizontal water pipe 141, allowing it to move along the horizontal water pipe 141 and eventually enter the input pipe 143. At this point, due to water pressure, the water flows into the leak-proof pipe 144, and the water pressure pushes the sealing block 24 and the sealing plate 25 upwards, thereby creating a gap between the sealing block 24 and the ramp 23. The water can be poured into the lower surface of the culture tray 13 through the gap. After the water is added, the sealing block 24 is re-attached to the slope 23 by gravity, and then the output pipe 21 is resealed to prevent water leakage. This allows water to be added to both the upper and lower surfaces of the culture tray 13 at the same time, so that the upper and lower surfaces of the culture medium can absorb distilled water at the same time, thereby making the culture medium wet faster and the humidity of the upper and lower surfaces uniform. This effectively prevents errors caused by inconsistent humidity of the upper and lower surfaces of the culture medium. Then the sealing door 2 can be closed to seal the heat insulation shell 12, so that microbial culture can be carried out in a closed environment.
[0023] The sealed door 2 is also equipped with an observation plate 5 made of transparent material, which allows the culture tray 13 to be observed without opening the sealed door 2, thereby preventing the opening of the sealed door from causing bacterial contamination or affecting the humidity and temperature inside the heat insulation shell 12.
[0024] The bottom of the main unit 1 is equipped with a support block 4, which helps to lift the main unit 1, so that the bottom of the main unit 1 will not directly contact the ground, thereby improving heat dissipation and reducing the probability of bacterial contamination.
[0025] The control base 11 has a control board 3 embedded on its outer surface, which facilitates the convenient control of the control base 11 through the control board 3.
[0026] Several electric heating tubes 17 are fixedly installed on the inner wall of the heat insulation shell 12, which is beneficial to control the temperature inside the heat insulation shell 12 through the electric heating tubes 17.
[0027] Several exhaust fans 16 are installed on the inner wall of the heat insulation shell 12, which can be used to adjust the temperature inside the heat insulation shell 12 and to draw in gases such as oxygen to adjust the air composition inside the heat insulation shell 12.
[0028] The horizontal water pipe 141 is provided with a connecting pipe 142 at the end outside the heat insulation shell 12. It can be a threaded pipe structure, which makes it easier and more convenient to connect the horizontal water pipe 141 to the external water source.
[0029] The bottom surface of the sealing block 24 has a square extension block 26 integrally formed, which helps to increase the weight of the sealing block 24, thereby making the seal more firm and stable when the sealing block 24 is in a sealed state.
[0030] The working principle of this utility model is as follows: When using this utility model, the culture medium is placed into the culture tray 13, and distilled water is supplied to the culture tray 13 from above through the upper water supply pipe 15, and distilled water is supplied to the culture tray 13 from below through the lower water supply pipe 14. The lower water supply pipe 14 is connected to an external distilled water source, and the distilled water is fed into the horizontal water pipe 141, moving along the horizontal water pipe 141 and finally entering the input pipe 143. At this time, due to the water pressure, the water flows into the leak-proof pipe 144, and the water pressure pushes the sealing block 24 and the sealing plate 25 upwards, thereby causing the sealing block 24 to contact the slope 25. A gap is created between the three sections, allowing water to flow through the gap into the lower surface of the culture tray 13. After water addition, gravity causes the sealing block 24 to re-adhere to the slope 23, thereby resealing the output pipe 21 to prevent leakage. This allows water to be added to both the upper and lower surfaces of the culture tray 13 simultaneously, enabling the culture medium to absorb distilled water on both sides at the same time. This results in faster wetting of the culture medium and uniform humidity on both sides, effectively preventing errors caused by inconsistent humidity on both sides of the culture medium. Then, the sealing door 2 can be closed to seal the heat insulation shell 12, allowing microbial culture to be carried out in a closed environment.
