Description

Technical Field

[0001] This utility model belongs to the field of incubator technology, and specifically relates to a biochemical incubator for cosmetic production. Background Technology

[0002] With the improvement of people's living standards and the increasing pursuit of beauty, the cosmetics industry has experienced rapid development in recent years. As products that come into direct contact with human skin, the safety and stability of cosmetics are of paramount importance. In the research, development, production, and quality control of cosmetics, the support of a laboratory environment is indispensable for various stages, including microbial contamination detection, stability assessment of active ingredients, and efficacy verification of functional components. Biochemical incubators are experimental devices capable of simulating specific temperatures, humidity levels, and clean environments, and are widely used in fields such as bioengineering, pharmaceuticals, food, and cosmetics. Especially in the cosmetics industry, they are primarily used for key stages such as microbial cultivation and detection, raw material fermentation, cell culture, and product stability testing.

[0003] Traditional biochemical incubators typically use simple hinged doors with manual closing mechanisms, lacking effective automatic locking systems. In laboratory environments, personnel movement, equipment vibration, or accidental operation can easily cause the doors to open unintentionally, disrupting the constant temperature and humidity environment inside the incubator and even introducing external contaminants, severely impacting the reliability of experimental data. Furthermore, the incubator's sealing structure often relies on fixed sealing strips, which are prone to aging and deformation after prolonged use, leading to a decrease in sealing effectiveness. In addition, conventional sealing structures cannot dynamically compensate for pressure fluctuations or slight vibrations in the external environment, resulting in a reduction in the cleanliness of the incubator's interior.

[0004] Therefore, it is necessary to design a biochemical incubator for cosmetic production to solve the above-mentioned technical problems. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model proposes a biochemical incubator for cosmetic production, which can avoid the problem of accidental opening of the door due to personnel movement, equipment vibration or accidental operation.

[0006] The technical solution of this utility model is: This utility model proposes a biochemical incubator for cosmetic production, comprising an incubator body, a temperature control panel on one side of the top of the incubator body, and a sealing door rotatably connected to the side wall of the incubator body. The incubator body is characterized by having a mounting bracket fixedly connected to the left side, a downward pressure rod slidably connected to the top of the mounting bracket, a pull ring fixedly connected to the top of the downward pressure rod, a right-angle locking block fixedly connected to the bottom of the downward pressure rod, a return spring fixedly connected to the top of the right-angle locking block, and an end of the return spring away from the right-angle locking block fixedly connected to the side wall of the mounting bracket. An L-shaped locking rod is fixedly connected to the left side of the sealing door.

[0007] Preferably, a temperature control box is fixedly connected to the inner wall of the incubator body, a motor is fixedly connected to the inner wall of the incubator body, and a fan is fixedly connected to the output end of the motor.

[0008] Preferably, a heater is fixedly connected to the side wall of the temperature control box, a cooler is provided at the bottom of the inner wall of the incubator body, and a temperature sensor is fixedly connected to the top of the inner wall of the incubator body.

[0009] Preferably, a hydraulic tank is fixedly connected to the top of the inner wall of the incubator body, a connecting spring is fixedly connected to the inner wall of the hydraulic tank, a pressing plate is fixedly connected to the end of the connecting spring away from the hydraulic tank, a pressing rod is fixedly connected to the side wall of the pressing plate, and the end of the pressing rod away from the pressing plate passes through the hydraulic tank and extends to the outside of the hydraulic tank.

[0010] Preferably, a drain pipe is connected to the side wall of the hydraulic tank, and a sealing box is fixedly connected to the end of the drain pipe away from the hydraulic tank. The side wall of the sealing box is fixedly connected to the outer surface of the incubator body, and an air bladder is fixedly connected to the inner wall of the sealing box.

[0011] Preferably, the inner wall of the temperature control box is fixedly connected to a guide rail plate, the side wall of the guide rail plate is provided with a placement plate, the outer surface of the guide rail plate is fixedly connected to a slide rod, the outer wall of the slide rod is slidably connected to a lower pressure plate, the top of the lower pressure plate is fixedly connected to a helical spring, and the end of the helical spring away from the lower pressure plate is fixedly connected to the outer wall of the guide rail plate.

[0012] Preferably, a guide rod is fixedly connected to the side wall of the lower pressure plate, and a guide plate is slidably connected to the outer wall of the guide rod. The guide plate passes through the side wall of the guide rail plate and extends to the outside.

[0013] This utility model has the following advantages and effects compared with the prior art: 1. This biochemical incubator for cosmetic production allows for manual opening of the sealed door and pulling out the placement plate along the guide rail. The cosmetic sample to be cultured or tested is then placed stably on the placement plate. After sample loading, the sealed door is closed. As the door closes, the L-shaped locking rod fixed on its left side contacts the right-angle locking block installed on the left side of the incubator body, and they slide relative to each other along the inclined surface. This contact force causes the right-angle locking block to move upwards against the spring force of the return spring. When the L-shaped locking rod passes the right-angle locking block, the return spring pushes the right-angle locking block downwards to reset. At this point, the vertical end face of the right-angle locking block forms a limiting fit with the L-shaped locking rod, achieving the automatic locking function of the sealed door. This structure not only improves the reliability of the sealed door closure but also effectively prevents the door from opening due to external vibration or accidental contact, thereby ensuring the stability and cleanliness of the incubator's internal environment and preventing external air and contaminants from entering the chamber and affecting experimental results.

[0014] 2. In this biochemical incubator for cosmetic production, during the closing of the sealed door, the door pushes the extrusion rod inward, causing it to move along the direction of the hydraulic tank and extend into the incubator body. The extrusion rod drives the extrusion plate to move synchronously, thereby applying pressure to the hydraulic medium filled inside the hydraulic tank. Under the action of the extrusion plate, the liquid inside the hydraulic tank is compressed and discharged directionally through the drain pipe, flowing into the sealed chamber connected to it. As the liquid continues to flow in, the internal pressure of the sealed chamber increases, causing the air bladders on its inner wall to elastically expand. The expanded air bladders extend outward, tightly adhering to the joint area between the sealed door and the incubator body, forming a dynamically enhanced airtight barrier. This structure not only improves the overall sealing performance after the sealed door is closed, but also maintains the stability of the internal environment of the chamber through the flexible compensation effect of the air bladders when there are slight vibrations or pressure fluctuations in the external environment.

[0015] 3. This biochemical incubator for cosmetic production applies pressure to the guide plate during the closing of the sealed door, causing the guide plate to move inward along the guide rail towards the interior of the temperature control chamber. Because the guide plate has guide grooves that slide in conjunction with the guide rod, the grooves limit and guide the guide rod as the guide plate moves. With the continuous displacement of the guide plate, the guide rod drives the lower pressure plate downward along the slide bar, thereby applying pressure to the placement plate. When the sealed door is fully closed, the lower pressure plate finally fits tightly against the surface of the placement plate, achieving a locking function. This effectively prevents the placement plate from shaking or tilting due to external vibration or impact during handling, thus avoiding sample container tipping, breakage, or contamination, significantly improving the safety and stability of the incubator during operation.

[0018] To enable those skilled in the art to better understand this utility model, the present utility model will now be further described in conjunction with specific embodiments.

[0019] Example 1: like Figures 1-7As shown, this utility model provides a biochemical incubator for cosmetic production, including an incubator body 101. A temperature control panel 102 is provided on the top of the incubator body 101. The temperature control panel 102 is used to set and display temperature parameters for easy user operation and monitoring. A sealing door 103 is rotatably connected to the side wall of the incubator body 101. A mounting bracket 201 is fixedly connected to the left side of the incubator body 101. A downward pressure rod 202 is slidably connected to the top of the mounting bracket 201, and a pull ring 20 is fixedly connected to the top of the downward pressure rod 202. 3. A right-angle locking block 204 is fixedly connected to the bottom end of the pressure rod 202, and a return spring 205 is fixedly connected to the top of the right-angle locking block 204. The end of the return spring 205 away from the right-angle locking block 204 is fixedly connected to the side wall of the mounting bracket 201. An L-shaped locking rod 206 is fixedly connected to the left side of the sealing door 103. This arrangement is such that when the sealing door 103 is closed, the L-shaped locking rod 206 fixed on its left side contacts the right-angle locking block 204 installed on the left side of the incubator body 101 and slides relative to it along its inclined surface. This contact force causes the right-angle locking block 204 to move upward against the elastic force of the return spring 205. After the L-shaped locking rod 206 passes the right-angle locking block 204, the return spring 205 pushes the right-angle locking block 204 downward to reset. At this time, the vertical end face of the right-angle locking block 204 and the L-shaped locking rod 206 form a limiting engagement, realizing the automatic locking function of the sealing door 103.

[0020] A temperature control box 31 is fixedly connected to the inner wall of the incubator body 101. A motor 301 is fixedly connected to the inner wall of the incubator body 101. A fan 302 is fixedly connected to the output end of the motor 301. This is so that the motor 301 drives the fan 302 to run and promote air circulation. A heater 303 is fixedly connected to the side wall of the temperature control box 31. A cooler 304 is provided at the bottom of the inner wall of the incubator body 101. A temperature sensor 305 is fixedly connected to the top of the inner wall of the incubator body 101. The temperature sensor 305 is used to monitor the internal temperature of the chamber in real time and feed the data back to the temperature control panel 102 to realize closed-loop control.

[0021] A hydraulic tank 401 is fixedly connected to the top of the inner wall of the incubator body 101. The hydraulic tank 401 is filled with hydraulic medium. A connecting spring 402 is fixedly connected to the inner wall of the hydraulic tank 401. A squeezing plate 403 is fixedly connected to the end of the connecting spring 402 away from the hydraulic tank 401. A squeezing rod 404 is fixedly connected to the side wall of the squeezing plate 403. The end of the squeezing rod 404 away from the squeezing plate 403 passes through the hydraulic tank 401 and extends to the outside of the hydraulic tank 401. A drain pipe 405 is connected to the side wall of the hydraulic tank 401. A sealing box 406 is fixedly connected to the end of the drain pipe 405 away from the hydraulic tank 401. The side wall of the sealing box 406 is fixedly connected to the outer surface of the incubator body 101. An airbag 407 is fixedly connected to the inner wall of the sealing box 406. This arrangement is such that when the airbag 407 inflates, it expands outward and closely adheres to the joint area between the sealing door 103 and the incubator body 101, forming a dynamically enhanced airtight barrier.

[0022] A guide rail plate 501 is fixedly connected to the inner wall of the temperature control box 31. A placement plate 502 is provided on the side wall of the guide rail plate 501. A slide rod 503 is fixedly connected to the outer surface of the guide rail plate 501. A lower pressure plate 504 is slidably connected to the outer wall of the slide rod 503. A coil spring 505 is fixedly connected to the top of the lower pressure plate 504. The end of the coil spring 505 away from the lower pressure plate 504 is fixedly connected to the outer wall of the guide rail plate 501. This is so that the coil spring 505 can pull the lower pressure plate 504 to reset. A guide rod 506 is fixedly connected to the side wall of the lower pressure plate 504. A guide plate 507 is slidably connected to the outer wall of the guide rod 506. The guide plate 507 is provided with a guide groove and forms a sliding fit with the guide rod 506. The guide plate 507 passes through the side wall of the guide rail plate 501 and extends to the outside.

[0023] In summary, the working principle of a biochemical incubator for cosmetic production according to this embodiment of the present invention is as follows: The operator first manually opens the sealing door 103 and pulls out the placement plate 502 along the guide rail 501. Then, the cosmetic sample to be cultured or tested is placed stably on the placement plate 502. After the sample loading is completed, the sealing door 103 is closed. As the sealing door 103 closes, the L-shaped locking rod 206 fixed on its left side contacts the right-angle locking block 204 installed on the left side of the incubator body 101 and slides relative to it along its inclined surface. This contact force causes the right-angle locking block 204 to move upward against the elastic force of the return spring 205. When the L-shaped lever 206 passes the right-angle lever 204, the return spring 205 pushes the right-angle lever 204 downward to reset. At this time, the vertical end face of the right-angle lever 204 and the L-shaped lever 206 form a limiting fit, realizing the automatic locking function of the sealing door 103. This structure not only improves the reliability of the sealing door 103 closing, but also effectively prevents the door from opening due to external vibration or accidental contact, thereby ensuring the stability and cleanliness of the incubator's internal environment and preventing external air and pollutants from entering the chamber and affecting the experimental results. During the closing of the sealing door 103, the door pushes the extrusion rod 404 inward, causing it to move along the direction of the hydraulic tank 401 and extend into the incubator body 101. The extrusion rod 404 drives the extrusion plate 403 to move synchronously, thereby applying pressure to the hydraulic medium filled inside the hydraulic tank 401. Under the action of the extrusion plate 403, the liquid inside the hydraulic tank 401 is compressed and discharged directionally through the drain pipe 405, flowing into the sealed box 406 connected to it. As the liquid continues to flow in, the internal pressure of the sealed box 406 increases, causing the air bladder 407 on its inner wall to elastically expand. The expanded air bladder 407 expands outward, tightly adhering to the joint area between the sealing door 103 and the incubator body 101, forming a dynamically enhanced airtight barrier. This structure not only improves the overall sealing performance after the sealing door 103 is closed, but also maintains the stability of the internal environment of the chamber through the flexible compensation effect of the air bladder 407 when there are slight vibrations or pressure fluctuations in the external environment. During the closing process of the sealing door 103, pressure is applied to the guide plate 507, causing it to move along the guide rail towards the interior of the temperature control chamber 31. Since the guide plate 507 has a guide groove that slides into the guide rod 506, the groove limits and guides the guide rod 506 as the guide plate 507 moves. With the continuous displacement of the guide plate 507, the guide rod 506 drives the lower pressure plate 504 to move downwards along the slide rod 503, thereby applying pressure to the placement plate 502. When the sealing door 103 is fully closed, the lower pressure plate 504 finally fits tightly against the surface of the placement plate 502, achieving a locking function. This effectively prevents the placement plate 502 from shaking or tilting due to external vibration or impact during handling, thus avoiding sample container tipping, breakage, or contamination, significantly improving the safety and stability of the incubator during operation. After sample loading is completed and the sealing door 103 is reliably closed, the operator can set the required operating temperature via the temperature control panel 102 located on the top of the incubator body 101. The control system automatically adjusts the operating status of the heater 303 and the cooler 304 according to the set value to achieve precise control of the ambient temperature inside the chamber. When heating is required, the heater 303 starts and heats the inside of the temperature control chamber 31. When the temperature is detected to be higher than the set range, the cooler 304 automatically starts to achieve the cooling function. At the same time, the motor 301 drives the fan 302 to operate synchronously, forcibly circulating the heated or cooled air into the temperature control chamber 31 to ensure uniform temperature distribution inside the chamber. The temperature sensor 305 collects the ambient temperature data inside the chamber in real time and feeds the signal back to the temperature control panel 102, forming a closed-loop temperature control system. This achieves high-precision temperature regulation and stable maintenance, meeting the constant temperature requirements of different experimental scenarios such as microbial culture, stability testing, and preservation of active ingredients in cosmetic production.

[0024] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. All equivalent changes and modifications made within the scope of the present utility model shall still fall within the scope of the present utility model.
