Description
Technical Field
[0001] This utility model relates to the field of cosmetic production technology, specifically to a low-temperature storage device for extracts. Background Technology
[0002] Serum is a highly concentrated and effective skin care product that usually contains a variety of active ingredients. It can deeply nourish the skin and achieve effects such as anti-aging, whitening, moisturizing, and repairing. In the process of making serum, some liquid needs to be extracted from plants. These extracts need to be stored at low temperatures during use to prevent them from deteriorating.
[0003] In the existing technology, refrigerators are often used to store such perishable liquids. These refrigerators are generally sealed with double doors and then the internal temperature of the refrigerator is reduced by a cooling machine. When taking out or storing the extract, the refrigerator must be opened manually and the extract stored to complete the storage operation.
[0004] There are some problems with using a refrigerator to store the extract. For example, opening the refrigerator once can cause the low temperature inside to have a significant impact. Also, when storing the extract, it is easy to place it near the glass of the refrigerator, which can lead to a higher storage temperature and cause deterioration. Therefore, we propose a low-temperature storage device for the extract. Utility Model Content

Corrugated sleeves are symmetrically provided on the upper and lower surfaces of the sliding frame, and the ends of the four corrugated sleeves are fixedly connected to the inner walls of the corresponding slide grooves. The two lead screws are located inside the corrugated sleeves at their respective positions, providing a transmission effect for the movement of the sliding frame.
[0011] Furthermore, the access mechanism also includes sprockets and chains. The sprockets are fixedly connected to the upper ends of the two lead screws, and the two sprockets are connected by a chain drive. Both the sprockets and the chain are located inside the equipment installation chamber, realizing the function of synchronous rotation of the lead screws on both sides.
[0012] Furthermore, the storage and retrieval mechanism also includes a motor, which is located on the front side of the upper side wall of the equipment installation chamber. The output shaft of the motor is fixedly connected to the upper end of the lead screw on the left side, and the input end of the motor is electrically connected to the output end of the controller to provide power for the movement of the sliding frame.

The upper front side of the material picking chamber is also hinged to the upper sealing plate by a pin. Tension springs are symmetrically fixedly connected to the upper surface of the upper sealing plate. The upper ends of the two tension springs are respectively fixedly connected to the lower side of the front side of a placement rack. A rectangular rubber sealing ring is fixedly connected to the upper side of the upper sealing plate to realize the function of opening and closing the storage cabinet.
[0014] Furthermore, the lower opening and closing mechanism also includes a top block, which is symmetrically fixedly connected to the lower side of the sliding frame. The upper surface of the upper sealing plate is symmetrically provided with longitudinal top grooves, which correspond to the upper and lower positions of the top block, thereby realizing the function of opening the upper sealing plate.

Detailed Implementation
[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4This embodiment provides a technical solution: a low-temperature storage device for extract, including a storage cabinet 1, a low-temperature pipe 3 on the rear side wall of the storage cabinet 1, an external cooling device connected to the upper end of the low-temperature pipe 3, a placement rack 2 inside the storage cabinet 1, a holding cylinder 11 inside the placement rack 2, a viewing glass window 10 in the middle of the front side of the storage cabinet 1, an equipment installation chamber 8 on the upper side of the storage cabinet 1, and also includes a lower opening and closing mechanism 4 and a storage and retrieval mechanism 6. When the low-temperature storage device is needed, the external cooling device can be installed inside the equipment installation chamber 8, and then the extract can be poured into the holding cylinder 11 in sequence. The external cooling device can be an EV series refrigerator air cooler. When using it, the cold air outlet pipe of the EV series refrigerator air cooler needs to be connected to the upper end of the low-temperature pipe 3.
[0026] Storage and retrieval mechanism 6 includes a slide 61, a sliding frame 63, electric push rods 64, and a lifting frame 65. The slide 61 is located on the front side of the left and right side walls of the storage cabinet 1. A sliding frame 63 is slidably connected inside the two slide 61s. The lower surface of the sliding frame 63 is provided with evenly distributed electric push rods 64. The telescopic ends of the three electric push rods 64 are respectively fixedly connected to the lifting frame 65 (the length of the lifting frame 65 is greater than the width of the container 11). Storage and retrieval mechanism 6 also includes lead screws 62, which are rotatably connected to the interior of the two slide 61s. The upper and lower surfaces of the sliding frame 63 are symmetrically provided with corrugated sleeves 9. The ends of the four corrugated sleeves 9 are respectively fixedly connected to the inner walls of the corresponding slide 61s. The two lead screws 62 are respectively located inside the corrugated sleeves 9 at their corresponding positions. Storage and retrieval mechanism 6 also includes a sprocket 66 and... Chain 67 and sprocket 66 are fixedly connected to the upper ends of two lead screws 62 respectively. The two sprockets 66 are connected by a chain 67. Both sprockets 66 and chain 67 are located inside the equipment installation chamber 8. The storage and retrieval mechanism 6 also includes a motor 68. The motor 68 is located on the front side of the upper side wall of the equipment installation chamber 8. The output shaft of the motor 68 is fixedly connected to the upper end of the lead screw 62 on the left side. The input end of the motor 68 is electrically connected to the output end of the controller 7. When the sliding frame 63 moves up and down, the two corrugated sleeves 9 on the upper side will also extend and retract synchronously. When the sliding frame 63 moves up, the two corrugated sleeves 9 on the upper side retract and the two corrugated sleeves 9 on the lower side extend. When the sliding frame 63 moves down, the two corrugated sleeves 9 on the upper side extend and the two corrugated sleeves 9 on the lower side retract, so that the corrugated sleeves 9 always seal the lead screw 62 and prevent the lead screw 62 from being contaminated.
[0027] The storage cabinet 1 also includes a controller 7, which is located on the upper front side of the storage cabinet 1. The input ends of the three electric push rods 64 are electrically connected to the output ends of the controller 7, and the input ends of the controller 7 are electrically connected to an external power source. A temperature and humidity sensor 5 is provided on the upper rear wall of the storage cabinet 1, and the temperature and humidity sensor 5 is bidirectionally electrically connected to the controller 7.
[0028] Lower opening and closing mechanism 4: It is located on the lower side of the front side of the storage cabinet 1. The lower opening and closing mechanism 4 includes an upper sealing plate 41, a material picking chamber 42, an outer baffle plate 43, and a tension spring 45 (the width of the lifting frame 65 is half the width of the upper sealing plate 41). The material picking chamber 42 is located on the front side of the lower side wall of the storage cabinet 1. The lower surface of the material picking chamber 42 is hinged to the outer baffle plate 43 by a pin. The upper front side of the material picking chamber 42 is also hinged to the upper sealing plate 41 by a pin. Tension springs 45 are symmetrically fixedly connected to the upper surface of the upper sealing plate 41. The upper ends of the two tension springs 45 are respectively fixedly connected to the lower side of the front side of a placement rack 2. A rectangular rubber sealing ring is fixedly connected to the upper side of the upper sealing plate 41. The lower opening and closing mechanism 4 also includes a top block 44. The top block 44 is symmetrically fixed to the lower side of the sliding frame 63. The upper surface of the upper sealing plate 41 has symmetrically formed longitudinal top grooves, which correspond vertically to the top block 44. At this point, the controller 7 can be adjusted, and the motor 68 will operate. The output shaft of the motor 68 will rotate in both directions, thereby driving the left lead screw 62 to rotate in both directions. This, in turn, drives the right lead screw 62 to rotate in both directions simultaneously via the sprocket 66 and chain 67, thus driving the sliding frame 63 to rotate in both directions. The sliding frame 63 can then be moved downwards until the top block 44 under the sliding frame 63 pushes against the longitudinal top groove, forcing the upper sealing plate 41 to rotate clockwise along the central axis of the upper pin, until the sliding frame 63 moves to its lowest position. 41 will also rotate 90 degrees clockwise along the central axis of the upper pin. At this time, the container 11 filled with extract can be placed on the lifting frame 65 through the lugs on both sides. Then, place the specified container 11 as needed. After filling, adjust the sliding frame 63 to move upward. When the sliding frame 63 moves upward so that the top block 44 no longer pushes the longitudinal top groove, the upper sealing plate 41 receives the tension of the tension spring 45, so that the upper sealing plate 41 seals the upper side of the material receiving chamber 42. After moving to the specified position, the controller 7 can be adjusted, the electric push rod 64 will operate, and the output shaft of the electric push rod 64 will extend, so that the container 11 lifted by the lifting frame 65 is inserted into the placement frame 2. Then, the height of the sliding frame 63 can be appropriately lowered so that the support... The lifting frame 65 is raised to prevent it from contacting the lugs of the holding cylinder 11. Then, the output shaft of the electric push rod 64 retracts. At this time, the external cooling equipment can be controlled, supplying cold air to maintain the internal temperature between 2℃ and 8℃. The cold air is then continuously discharged into the storage cabinet 1 through the low-temperature pipe 3. At this time, the controller 7 can be controlled, and the temperature and humidity sensor 5 operates. When the temperature changes, the NTC resistance value also changes, and the PTC resistance value also changes. When the NTC resistance value rises, the PTC resistance value falls, and when the NTC resistance value falls, the PTC resistance value rises. Consequently, the current or voltage in the circuit changes, which is then converted into a digital signal by the analog-to-digital converter (ADC). The temperature value is then calculated and returned to the controller 7.The humidity sensor 5 utilizes the adsorption or desorption properties of its internal moisture-sensitive material to convert humidity changes into electrical signals, which are then fed back to the controller 7. This monitors the temperature and humidity information within the storage cabinet 1, thereby adjusting the external cooling equipment to supply cool air to the storage cabinet 1. When it is necessary to remove the extract from the storage device, the above operation can be reversed. The lifting frame 65, which moves up, down, left, and right, lifts the container 11 and moves it into the unloading chamber 42. At this point, the outer cover 43 can be opened, and the container 11 can be removed.
[0029] The working principle of the low-temperature storage device for extract provided by this utility model is as follows: When the low-temperature storage device is needed, the external cooling equipment can be installed inside the equipment installation chamber 8. Then, the extract can be poured into the holding cylinder 11 in sequence. At this time, the controller 7 can be adjusted to operate the motor 68. The output shaft of the motor 68 rotates in both directions, thereby driving the left lead screw 62 to rotate in both directions. This, in turn, drives the right lead screw 62 to rotate in both directions synchronously through the sprocket 66 and the chain 67, thereby driving the sliding frame 63 to rotate in both directions. At this time, the sliding frame 63 can be moved downward until the top block 44 under the sliding frame 63 pushes the longitudinal top groove, forcing the upper seal to be closed. The upper sealing plate 41 rotates clockwise along the central axis of the upper pin until the sliding frame 63 moves to its lowest position. The upper sealing plate 41 also rotates 90 degrees clockwise along the central axis of the upper pin. At this point, the container 11 filled with extract can be placed onto the lifting frame 65 via the lugs on both sides. Then, the designated container 11 can be placed as needed. After placement, the sliding frame 63 can be adjusted to move upwards. When the sliding frame 63 moves upwards and the top block 44 no longer pushes against the longitudinal top groove, the upper sealing plate 41 receives the tension of the tension spring 45, causing the upper sealing plate 41 to seal the upper side of the material receiving chamber 42. After moving to the designated position, the controller 7 can be adjusted to operate the electric push rod 64. The output shaft of the electric push rod 64 extends, inserting the container 11, which is being lifted by the lifting frame 65, into the placement rack 2. Then, the height of the sliding frame 63 can be appropriately lowered so that the lifting frame 65 no longer contacts the lugs of the container 11. The output shaft of the electric push rod 64 then retracts. At this point, the external cooling equipment can be activated, supplying cold air, which is continuously discharged into the storage cabinet 1 through the low-temperature pipe 3. The controller 7 can then be activated, and the temperature and humidity sensor 5 will operate. When the temperature changes, the NTC resistance value will also change, and the PTC resistance value will change accordingly. When the NTC resistance value increases, the PTC resistance value decreases; when the NTC resistance value decreases, the PTC resistance value increases. As the current or voltage in the circuit changes, it is converted into a digital signal by the analog-to-digital converter (ADC), and the temperature value is calculated and returned to the controller 7. At the same time, the adsorption or desorption characteristics of the moisture-sensitive material inside the temperature and humidity sensor 5 convert the humidity change into an electrical signal, which is returned to the controller 7 to monitor the temperature and humidity information in the storage cabinet 1. Then, the external cooling equipment is adjusted to supply cold air to the storage cabinet 1. When it is necessary to take out the extract in the storage device, the above operations can be reversed. The lifting frame 65, which moves up, down, left, and right, lifts the container 11 and moves it into the material taking chamber 42. At this time, the outer cover plate 43 can be opened and the container 11 can be taken out.
[0030] It is worth noting that the core chip of the controller 7 disclosed in the above embodiments is a microcontroller, specifically the STM32f103c8t6. The temperature and humidity sensor 5 and the electric actuator 64 can be freely configured according to the actual application scenario. It is recommended to use the XD-103C model temperature and humidity collector for the temperature and humidity sensor 5, and the TL-10 electric actuator for the electric actuator 64. The controller 7 controls the operation of the temperature and humidity sensor 5 using methods commonly used in the prior art.
