Description

Technical Field

[0001] This utility model relates to the field of incubator equipment technology, and in particular to an incubator for pharmaceutical microbial detection. Background Technology

[0002] Pharmaceutical microbial testing incubators are core equipment in the pharmaceutical industry and laboratories used to provide a stable environment for the growth and reproduction of microorganisms. By precisely controlling parameters such as temperature, humidity, and gas composition, they ensure the accuracy and reliability of pharmaceutical microbial testing results. In the stages of drug research and development, quality control, and safety assessment, the performance of the incubator directly affects the success or failure of microbial testing. Therefore, its structural design and functional optimization have always been a key focus of the industry.

[0003] Early incubators for pharmaceutical microbial testing had relatively simple internal support structures, using fixed-height metal supports or single-layer shelves. Adjusting the height required manual disassembly and reassembly with a screwdriver, a cumbersome and time-consuming process that couldn't meet the need for rapid switching between different sized culture containers. With technological advancements, existing incubators have added slot-type or bolt-adjustable supports, enabling simple height adjustment. However, these structures still have significant drawbacks: fixed slot spacing leads to insufficient height adjustment precision, while bolt adjustments require repeated tightening, resulting in low efficiency. In actual testing, when researchers frequently change culture dishes and shake flasks of different heights, the existing support structures, lacking rapid positioning and adaptive adjustment capabilities, require multiple trial installations to match the container height. This not only prolongs experimental preparation time but also causes the support to loosen due to repeated disassembly and reassembly, affecting the stability of sample placement and potentially interfering with the uniformity of the microbial culture environment.

An arc-shaped inclined block 205 is fixedly connected to the outer side of which a return spring 206 is fixedly connected. The other end of the return spring 206 is fixedly connected to the inner wall of the hollow cylinder 202. Rotating and pressing the cylinder 204 causes it to move upward along the threaded cylinder 203. Under the action of the return spring 206, the arc-shaped inclined block 205 contracts, thereby engaging with the inclined retaining ring groove 207 above, thus releasing the lock between the hollow cylinder 202 and the limiting rod 201. The top of the hollow cylinder 202 is slidably connected to an inclined... The inclined extrusion block 209 has multiple inclined retaining ring grooves 207 on its outer wall. The outer wall of the hollow cylinder 202 is rotatably connected to the placement disc 208. The extrusion cylinder 204 is rotated to move down along the threaded cylinder 203, thereby extruding the inclined extrusion block 209 down.

[0037] Specifically, the rotating extrusion cylinder 204 moves upward along the threaded cylinder 203, and the arc-shaped inclined block 205 contracts under the action of the return spring 206, thereby engaging with the inclined retaining ring groove 207 above, thus releasing the lock between the hollow cylinder 202 and the limiting rod 201. Subsequently, the placement disc 208 is moved, thereby driving the hollow cylinder 202 to move above the limiting rod 201, thereby adjusting the position of the placement disc 208 above the limiting rod 201 as needed. Then, the extrusion cylinder 204 is rotated downward along the threaded cylinder 203, thereby extruding the inclined extrusion block 209 downward, and due to its inclined characteristic, the arc-shaped inclined block 205 moves, causing the return spring 206 to be stretched, and the arc-shaped inclined block 205 to engage with the corresponding inclined retaining ring groove 207, thereby completing the fixation of the placement disc 208.

The outer walls of the multiple air inlets 301 are opened at the bottom front side of the outer wall of the housing 1. An air intake filter 302 is fixedly connected to the inner wall of the bottom end of the housing 1. An arc-shaped cavity 303 is opened on the rear side of the inner wall of the housing 1. When the air intake filter 302 is activated, outside air enters the air intake filter 302 through the air inlets 301 and enters the arc-shaped cavity 303. A partition plate 304 is fixedly connected to the middle of the inner wall of the arc-shaped cavity 303, dividing the arc-shaped cavity 303 into two areas. Multiple inclined air outlet guide plates 305 are fixedly connected to the left side of the inner wall of the arc-shaped cavity 303, and multiple inclined air intake guide plates 306 are fixedly connected to the right side of the inner wall of the arc-shaped cavity 303. Under the guidance of the inclined air outlet guide plates 305, the air is blown into the housing 1 at an inclined angle. When the blown airflow... After circling the inner chamber 1, the airflow is then reintroduced into the right-side arc-shaped cavity 303 via the inclined air intake guide plate 306. A purification component 307 is provided on the top right side of the arc-shaped cavity 303. The purification component 307 includes a processing chamber 3071. The outer wall of the processing chamber 3071 is opened at the top of the chamber 1. The bottom end of the processing chamber 3071 is connected to the top right side of the arc-shaped cavity 303. A photocatalyst plate 3072 is fixedly connected to the middle of the inner wall of the processing chamber 3071. An ultraviolet lamp 3073 is fixedly connected to the top of the photocatalyst plate 3072.

Then, driven by the exhaust fan 3074, the filtered airflow is discharged.

[0039] Specifically, by activating the air intake filter 302, outside air enters the air intake filter 302 through the air intake 301 and then enters the arc-shaped cavity 303. The partition plate 304 divides the arc-shaped cavity 303 into two areas. The air processed by the air intake filter 302 enters the arc-shaped cavity 303 on the left side. Guided by the inclined air outlet guide plate 305, the air is blown into the chamber 1 at an inclined angle. After the blown airflow circles the chamber 1, it is reintroduced into the arc-shaped cavity 303 on the right side by the inclined air intake guide plate 306, and finally flows into the purification component 307. Under the action of the photocatalyst plate 3072 and the ultraviolet lamp 3073 in the processing chamber 3071, the incoming airflow is purified and filtered. Then, driven by the exhaust fan 3074, the filtered airflow is discharged, so that the airflow can flow more evenly in the chamber 1, thereby ensuring a clean and sterile culture environment.

[0041] Specifically, the magnetic sealing ring 601 ensures that the door 4 can be firmly attached to the front side of the box body 1 when closed, and the groove 602 makes it easy to open the door 4, and also makes it easy for condensate or accidentally spilled liquid flowing out from the placement disc 208 to flow out from the filter slit 702 and fall into the collection trough 701, so as to facilitate collection and subsequent cleaning.

[0042] Reference Figure 1 , Figure 2 and Figure 4 A display device 8 is fixedly connected to the top left of the front of the chamber 1. The display device 8 can intuitively display various key parameters inside the incubator. Multiple control switches 9 are fixedly connected to the top right of the front of the chamber 1. The control switches 9 can realize the operation of the incubator. A pressure-resistant transparent plate 10 is fixedly connected to the middle of the front side of the chamber door 4. The pressure-resistant transparent plate 10 can directly observe the culture status of the samples inside the chamber. A sealing sleeve 11 is fixedly connected to the outer wall of the pressure-resistant transparent plate 10. The sealing sleeve 11 can prevent gas leakage inside the chamber and prevent external pollutants from entering the chamber. An exhaust hole 12 is opened at the top of the chamber 1. The exhaust hole 12 can ensure that the air treated by the purification component 307 can be smoothly discharged from the chamber. The bottom end of the exhaust port 12 of the body 1 is connected to the top of the exhaust fan 3074; the outer wall size of the threaded cylinder 203 is the same as the inner wall size of the extrusion cylinder 204, which can control the extension and retraction state of the arc-shaped inclined block 205. The outer wall of the arc-shaped inclined block 205 is engaged with the inner wall of the placement disc 208, so that the placement disc 208 will not shake or fall off at will; the inner wall of the hollow cylinder 202 is slidably connected to the outer wall of the limiting rod 201, providing the hollow cylinder 202 with the freedom to move up and down along the limiting rod 201; one end of the air intake filter 302 is connected to the bottom left side of the arc-shaped cavity 303, to prevent these pollutants from entering the interior of the chamber 1 and contaminating the culture environment;

[0043] Specifically, the display device 8 can intuitively display various key parameters inside the incubator, allowing operators to monitor the culture environment at any time. The control switch 9 can control the temperature, start / stop airflow circulation, switch the lighting on / off, and start the sterilization program. Meanwhile, the pressure-resistant transparent plate 10 allows direct observation of the culture status of the samples inside the incubator, reducing the number of times the incubator needs to be opened and maintaining a stable environment inside. The sealing sleeve 11 prevents gas leakage inside the incubator, avoiding external contaminants from entering the incubator and ensuring the airtightness and cleanliness of the culture environment. The exhaust vent 12 ensures that the air treated by the purification component 307 can be smoothly discharged from the chamber 1, maintaining airflow inside the incubator. The circulating flow, and the outer wall size of the threaded cylinder 203 is the same as the inner wall size of the extrusion cylinder 204, can control the extension and retraction state of the arc-shaped inclined block 205. The outer wall of the arc-shaped inclined block 205 is engaged with the inner wall of the placement disc 208, so that the placement disc 208 will not shake or fall off at will. The inner wall of the hollow cylinder 202 is slidably connected to the outer wall of the limiting rod 201, providing the hollow cylinder 202 with the freedom to move up and down along the limiting rod 201, thereby realizing the flexible adjustment of the height of the placement disc 208. Subsequently, it can prevent these pollutants from entering the interior of the chamber 1 and contaminating the culture environment, and ensure the cleanliness of the air entering the chamber.

[0044] Working principle: First, when adjusting the height of the placement disc 208, the extrusion cylinder 204 should be rotated to move upward along the threaded cylinder 203. At this time, the arc-shaped inclined block 205 retracts under the action of the return spring 206, releasing the engagement with the inclined retaining ring groove 207 above, and the locking state between the hollow cylinder 202 and the limiting rod 201 is released. Then, the placement disc 208 is moved, driving the hollow cylinder 202 to move above the limiting rod 201 to adjust the position of the placement disc 208 above the limiting rod 201. After the adjustment is completed, the extrusion cylinder 204 is rotated again to move downward along the threaded cylinder 203, and the extrusion inclined block 209 moves downward accordingly. Due to the inclined characteristics of the arc-shaped inclined block 205, the return spring 206 is stretched, and the arc-shaped inclined block 205 re-engages with the inclined retaining ring groove 207, thereby fixing the placement disc 208.

[0045] Furthermore, through the circulating airflow mechanism 3, by activating the air intake filter 302, outside air enters the device through the air intake 301 and further enters the arc-shaped cavity 303. The partition plate 304 divides the arc-shaped cavity 303 into two independent areas. The air processed by the air intake filter 302 flows into the arc-shaped cavity 303 on the left and is blown into the chamber 1 at an inclined angle under the action of the inclined air outlet guide plate 305. After the airflow circulates once inside the chamber 1, the inclined air intake guide plate 306 reintroduces it into the arc-shaped cavity 303 on the right. Finally, the airflow flows into the purification component 307, where the airflow is purified and filtered under the synergistic action of the photocatalyst plate 3072 and the ultraviolet lamp 3073. Subsequently, driven by the exhaust fan 3074, the purified airflow is discharged, ensuring uniform airflow within the chamber 1 and thus maintaining a clean and sterile culture environment.
