Description

Technical Field

[0001] This application relates to the technical field of thawing devices, and in particular to a thawing device with a one-way water inlet structure. Background Technology

[0002] Thawing devices are used in fields such as biopharmaceuticals, medical education, public health and disease control, drug testing, and food. Traditional thawing methods typically involve placing cryovials or thawing bottles directly in a constant-temperature water bath. This method suffers from problems such as imprecise temperature control, potential sample contamination by the thawing solution, cumbersome operation, and low efficiency. In particular, when processing multiple samples, it is difficult to ensure that the thawing conditions are consistent for each sample.

[0003] Existing technologies include water bath shakers or thawing devices that attempt to promote heat exchange through shaking motion. However, most of these devices directly immerse the thawing flasks in a shared water bath, where the thawing solution (usually water or a specific culture medium) can easily backflow into the flasks through the opening or gaps during shaking, posing a risk of sample contamination. Furthermore, ordinary shaking motion leads to chaotic water flow, making it impossible to establish a stable and controllable fluid path, thus affecting the uniformity and efficiency of thawing. Summary of the Invention

[0004] This application provides a thawing device with a one-way water inlet structure. The device, through a unique one-way water inlet structure combined with shaking motion, can drive the thawing fluid to flow directionally and unidirectionally over the outer wall of the thawing bottle, achieving efficient and uniform thawing, while effectively preventing the thawing fluid from flowing back and contaminating the sample or bottle opening.

[0005] According to some embodiments, this application provides a defrosting device with a one-way water inlet structure, comprising: The container includes a liquid storage chamber for storing thawing fluid; a shaking section disposed within the liquid storage chamber and capable of being shaken back and forth; and a bottle fixing section, at least one of which is disposed on the shaking section and used to fix a thawing bottle. The bottle fixing section has a one-way water inlet structure, allowing the thawing fluid to flow unidirectionally into the bottle fixing section to thaw the thawing bottle during the shaking process using the interaction force between the thawing section and the thawing fluid.

[0006] A further technical solution is that the shaking part includes a support member located in the liquid storage cavity and used for bearing and positioning, and a driving member for driving the support member to move back and forth in the liquid storage cavity or stay at a preset position; the support member is provided with a plurality of bearing and positioning holes, each of the bearing and positioning holes is used for the bottle fixing part to bear and position, so that the bottle fixing part remains stable in the process of following the movement of the support member.

[0007] A further technical solution is that the bottle fixing part includes a thawing bucket, which is tightly supported in the supporting positioning hole, and its lower end is located below the liquid surface of the liquid storage cavity; the side wall of the thawing bucket is provided with at least one water inlet hole communicating with the interior, the water inlet hole being used to allow the thawing liquid in the liquid storage cavity to enter the thawing bucket; the thawing bottle is disposed in the thawing bucket, and an annular gap for water flow is left between the inner walls of the two; the one-way water inlet structure is disposed at the position of the water inlet hole of the thawing bucket, so as to control the thawing liquid in the liquid storage cavity to pass unidirectionally through the water inlet hole to enter the annular gap in the thawing bucket to thaw the thawing bottle.

[0008] A further technical solution is that the one-way water inlet structure includes a fixed diaphragm, which is disposed on the inner wall of the thawing bucket; the fixed diaphragm is provided with a movable diaphragm that corresponds to the position of the water inlet hole and is larger in size than the water inlet hole; the movable diaphragm can open towards the side of the thawing bottle inside the thawing bucket under the impact of external water flow to achieve liquid inlet.

[0009] A further technical solution is that the unidirectional water inlet structure also includes a fixing frame, and the fixing diaphragm is disposed between the fixing frame and the inner wall of the thawing tank; the fixing frame is fixed to the inner wall of the thawing tank to shape and keep the fixing diaphragm fixed; the fixing frame is provided with a water inlet corresponding to the position of the movable diaphragm, and the size of the water inlet is larger than the size of the movable diaphragm to allow the movable diaphragm to move.

[0010] A further technical solution is that the water inlet holes are spaced out in a ring around the outer peripheral wall of the thawing bucket; the fixed diaphragm is set in a ring shape and is attached to the inner peripheral wall of the thawing bucket, and the number and position of the movable diaphragms correspond to the number and position of the water inlet holes, with each water inlet hole equipped with a movable diaphragm for control.

[0011] A further technical solution is that the fixing frame is configured as a ring, the fixing frame is attached to the inner peripheral wall of the fixed diaphragm, and the number and position of the water inlets correspond to the number and position of the movable diaphragms.

[0012] A further technical solution is that the water inlet is located near the bottom of the thawing bucket, so that water flows from bottom to top through the annular gap between the thawing bucket and the thawing bottle.

[0013] A further technical solution is that an elastic element is connected to the inner wall of the defrosting bucket, and the elastic element abuts against the defrosting bottle to fix the defrosting bottle and make it rigidly follow the shaking part during the defrosting process.

[0014] A further technical solution is that the elastic element is configured as a plurality of elements, and the plurality of elastic elements are arranged at intervals along the height direction of the thawing bucket.

[0015] The embodiments of this disclosure have at least the following advantages: Thawing fluid is added to the storage chamber, and then the thawing bottle is fixed to the bottle holder of the shaking unit. As the shaking unit shakes within the storage chamber, it causes the bottle holder to shake synchronously. The impact of the thawing fluid during shaking opens the one-way water inlet structure, allowing the thawing fluid in the storage chamber to continuously flow unidirectionally into the bottle holder and flush the thawing bottle. This achieves active renewal of the thawing fluid and efficient heat exchange, resulting in fast and uniform thawing. The one-way water inlet structure, located at the inlet hole, acts like a one-way valve, allowing only thawing fluid to flow from the storage chamber into the thawing container through the inlet hole, while essentially preventing backflow. This continuous flow of fresh thawing fluid during shaking, flushing the thawing bottle, greatly enhances heat exchange efficiency and thawing uniformity. This device is simple and ingenious in structure, provides uniform thawing, and effectively controls the liquid flow direction.

[0016] In this embodiment, the one-way water inlet structure utilizes the interaction force between the shaking part and the thawing fluid during shaking. This interaction force is used as the driving force to control the opening operation of the one-way water inlet structure, allowing the thawing fluid to enter from the bottom and overflow from the top. This eliminates the need for a one-to-one correspondence between pipelines and a drive pump. Furthermore, this design means that the thawing bottle does not need to be completely immersed in the liquid in the storage chamber; only a portion of the thawing bottle is submerged. This reduces the risk of liquid contamination at the thawing bottle opening (the thawing fluid entering the thawing tank only contacts the outer wall of the thawing bottle and does not come into contact with the sample inside the bottle. Therefore, the overflowing liquid remains clean and can be safely returned to the common storage chamber to participate in the circulation, eliminating the risk of cross-contamination). Moreover, because the thawing bottle does not need to be completely immersed in the liquid in the storage chamber, the amount of thawing fluid used can be reduced while ensuring the contact height between the thawing fluid and the thawing bottle, thereby ensuring thawing efficiency.

[0017] Secondly, the thawing fluid enters each thawing tank uniformly from the storage chamber, eliminating the need to control the temperature of the thawing fluid in each tank separately. It is only necessary to maintain a constant temperature of the thawing fluid within the storage chamber, which improves throughput and consistency.

[0018] The core advantage of this structure lies in using only one shaking section to provide forced convection heat exchange between the frozen product and the thawed portion inside the thawing bottle, while simultaneously providing driving force for the thawing fluid. This enhances heat exchange along the heat transfer path from the thawing fluid to the frozen product, thereby improving thawing efficiency. Specifically, during the shaking process, fresh thawing fluid is continuously replenished into the thawing container, directly flushing the thawing bottle. This achieves the first layer of forced convection heat exchange between the thawing fluid and the outer wall of the thawing bottle. Simultaneously, under the thawing action of the thawing fluid, the thawed and uncold portions inside the thawing bottle achieve a second layer of forced convection heat exchange through the shaking action of the shaking section. Therefore, this design significantly improves the thawing efficiency of the thawing bottle. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details are presented in the various embodiments of this application to facilitate a better understanding of the application. However, the technical solutions claimed in this application can be implemented even without these technical details and various variations and modifications based on the following embodiments. The division of the various embodiments below is for ease of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

[0023] The following describes in detail a thawing device with a one-way water inlet structure provided in this embodiment, with reference to the accompanying drawings. Figure 1 As shown, it includes: a liquid storage chamber 1, a shaking part 2, and a bottle fixing part 3. The liquid storage chamber 1 is a rectangular structure with an open top, and a liquid storage tank is formed inside for storing thawing fluid. The shaking part 2 is disposed inside the liquid storage chamber 1 and can be shaken back and forth. At least one bottle fixing part 3 is disposed on the shaking part 2 and is used to fix the thawing bottle 4. The bottle fixing part 3 is provided with a one-way water inlet structure, which allows the thawing fluid to flow into the bottle fixing part 3 in one direction to thaw the thawing bottle 4 during the shaking process of the shaking part 2.

[0024] In this embodiment, the storage tank of the storage cavity 1 contains a constant-temperature thawing solution (e.g., 37°C warm water). By placing the bottle fixing part 3 on the shaking part 2, the bottle fixing part 3 can be shaken synchronously during the shaking process in the storage cavity 1. During the shaking process, an interaction force is generated between the bottle fixing part 3 and the thawing solution. With the help of the impact of the thawing solution, the one-way water inlet structure can be opened, so that the thawing solution in the storage cavity 1 can continuously enter the interior of the bottle fixing part 3 through the one-way water inlet structure to thaw the thawing bottle 4. When too much thawing solution enters the bottle fixing part 3, the thawing solution will overflow from the top of the bottle fixing part 3 and flow back into the storage cavity 1, so that the thawing solution on the surface of the thawing bottle 4 is constantly circulating. In this way, shaking can accelerate the circulation of the thawing solution, realize the rapid thawing of the thawing bottle 4, and improve the thawing efficiency. Furthermore, this device has a simple structure. The one-way water inlet structure uses the interaction force between the shaking part 2 and the thawing liquid during the shaking process. It is this interaction force that is used as the driving force to control the opening operation of the one-way water inlet structure.

[0025] Please continue to refer to Figure 1As shown in this embodiment, it should be noted that the shaking part 2 includes a carrier located inside the liquid storage cavity 1 and used for bearing and positioning, and a driving member for driving the carrier to move back and forth inside the liquid storage cavity 1 or stay at a preset position. The carrier is provided with a number of bearing and positioning holes, each bearing and positioning hole is used for positioning the bottle fixing part 3, so that the bottle fixing part 3 remains stable during the movement of following the carrier.

[0026] In one example, the support component includes a support platform. The material of the support platform can be selected from corrosion-resistant and easy-to-clean engineering plastics or metals, depending on the requirements. The surface of the support platform has an array of circular support positioning holes. The number of bottle fixing parts 3 is set to correspond to the number of support positioning holes. The diameter of the support positioning holes matches the outer diameter of the bottle fixing parts 3 to ensure a tight fit. The support positioning holes are fixed by the static friction between the inner wall and the outer wall of the bottle fixing parts 3 to prevent displacement or loosening during movement. Thus, by using a support platform, multiple thawing bottles 4 can be shaken in the liquid storage chamber 1 at one time, thereby improving work efficiency. The support platform is set in the liquid storage chamber 1 and is located above the liquid surface of the liquid storage tank. It is only necessary to ensure that when the bottle fixing parts 3 fix the thawing bottles 4, both the bottle fixing parts 3 and the lower part of the thawing bottles 4 are below the liquid surface of the liquid storage tank to allow liquid to enter. The support platform can be set as a flat plate structure with support positioning holes running through its upper and lower sides. Of course, the shaking method in this embodiment can be manual or automatic. In manual mode, vertically installed support rods are connected to the four ends of the underside of the support platform. Rollers are connected to the bottom of the support rods, supporting the bottom of the storage tank. This allows the platform to be manually pushed back and forth within the storage cavity 1, thus achieving the shaking motion. Alternatively, spring telescopic rods are connected to both ends of the support platform along the direction of movement. The end of the spring telescopic rod away from the support platform is connected to the inner wall of the storage cavity 1. The spring telescopic rods support the platform, allowing it to move linearly back and forth in the direction of movement under external force. In automatic mode, a driving component such as a drive motor can be used. The support platform can be connected to the drive motor via a guide rail or linkage mechanism. In this embodiment, the drive motor drives the support platform to perform horizontal reciprocating linear motion within the storage cavity 1. In other examples, a linear motor can be used as the driving component. The drive shaft of the linear motor passes through the storage cavity 1 and connects to the support platform for reciprocating linear motion. When the drive shaft of the linear motor passes through the storage cavity 1, a reliable dynamic seal (such as a mechanical seal or magnetohydrodynamic seal) is used to prevent liquid leakage. The support component can also be a relatively mature planar shaking table, which is configured to perform reciprocating linear motion. This embodiment does not impose specific restrictions on the particular method used.

[0027] In other examples, the support platform can also be driven by a drive motor to make circular motion in the liquid storage cavity 1. The support platform is set to be circular, and the bottom center of the support platform is rotated and set in the liquid storage cavity 1 through a rotating shaft. The output shaft of the drive motor passes through the liquid storage cavity 1 and converts power with the rotating shaft through gear transmission, thereby converting the power of the drive motor to the rotating shaft and controlling the support platform to make circular motion.

[0028] Please refer to Figure 1 , Figure 2 As shown in the illustration, in this embodiment, it should also be noted that the bottle fixing part 3 includes a thawing bucket 31. The bottom of the thawing bucket 31 is closed, and the top is open. The thawing bucket 31 is fixed in the bearing positioning hole, and the outer wall of the thawing bucket 31 is tightly fitted with the inner wall of the bearing positioning hole to ensure stability between the two. The bottom of the thawing bucket 31 is located below the liquid surface inside the liquid storage cavity 1. The thawing bottle 4 is inserted into the thawing bucket 31 from top to bottom, and an annular gap is left between them for water to flow through. The side wall of the thawing bucket 31 is also provided with a water inlet hole 311 that connects to the interior. The water inlet hole 311 is located near the bottom of the thawing bucket 31 and is arranged in a circle at equal intervals around the outer circumference of the thawing bucket 31. A one-way water inlet structure is respectively arranged at the position of each water inlet hole 311. In this embodiment, the water inlet hole 311 is set as a circular hole. In other embodiments, it can also be set as other shapes. This embodiment does not impose specific limitations.

[0029] In this embodiment, the thawing bottle 4 is fixed inside the thawing bucket 31, and an annular gap is left between the thawing bottle 4 and the thawing bucket 31. During the shaking process, the shaking part 2, through the interaction force with the thawing liquid, causes the thawing liquid to impact the one-way water inlet structure, opening the one-way water inlet structure. Thus, the thawing liquid can enter the interior of the thawing bucket 31 unidirectionally from the water inlet hole 311 at the bottom. Through the continuous shaking of the shaking part 2, the thawing liquid in the liquid storage chamber 1 can continuously enter the thawing bucket 31. Furthermore, when there is too much thawing liquid in the thawing bucket 31, the entering thawing liquid will also flow out of the thawing bucket 31. The annular gap between the freezing bottle 4 and the thawing container 31 allows for directional circulation from bottom to top, eventually overflowing from the top of the thawing container 31 or draining through other means. If overflowing from the top, the thawing fluid can return to the storage chamber 1, ensuring continuous circulation of the thawing fluid on the surface of the freezing bottle 4. Similarly, if too much thawing fluid enters the thawing container 31, the excess fluid will return from the top of the thawing container 31 to the storage chamber 1, maintaining continuous circulation of the thawing fluid on the surface of the freezing bottle 4. Therefore, shaking can accelerate the circulation of the thawing fluid, achieving rapid thawing of the freezing bottle 4 and improving thawing efficiency. It should also be noted that the bottom-inlet, bottom-up water flow path design conforms to the principle of thermal convection, enabling more effective heat exchange, removing cold air from the surface of the freezing bottle 4, avoiding uneven thawing, improving thawing efficiency, and reducing thawing dead zones.

[0030] Please refer to Figure 3 , Figure 4 as well as Figure 7 As shown in this embodiment, it should also be noted that the one-way water inlet structure includes a fixed diaphragm 51. A ring-shaped fixed diaphragm 51 made of silicone material is covered on the inner peripheral wall of the thawing tank 31. The fixed diaphragm 51 is provided with movable diaphragms 511 corresponding to the position and number of water inlet holes 311. The edges of the movable diaphragms 511 are connected to the main body of the fixed diaphragm 51 by cutting or molding, so that they can open inward toward the inside of the thawing tank 31 (i.e. toward the thawing bottle 4). The size of the movable diaphragm 511 is larger than the size of the water inlet hole 311. The movable diaphragm 511 opens inward under the impact of the water flow outside the thawing tank 31. When the shaking part 2 is stationary, the movable diaphragm 511 adheres to the water inlet 311 to achieve a seal. When the shaking part 2 is running, it causes the bottle fixing part 3 to shake back and forth in the thawing fluid in the liquid storage chamber 1. When the bottle fixing part 3 shakes, the thawing bucket 31 on the bottle fixing part 3 is impacted along the direction of movement. As a result, the movable diaphragm 511 opens inward under the impact of the thawing fluid. At this time, the water inlet 311 opens, and the thawing fluid can enter the thawing bucket 31 through the water inlet 311 to thaw the thawing bottle 4. In other words, When the thawing bucket 31 is shaken, the external water flow creates a pressure difference on the movable diaphragm 511, causing the movable diaphragm 511 to open inward, allowing water to enter. When the water flow reverses or the pressure is balanced, the movable diaphragm 511 closes under its own elasticity or the action of the water flow, covering the water inlet 311 and achieving unidirectional flow. Because the size of the movable diaphragm 511 is larger than the size of the water inlet 311, the movable diaphragms 511 in other positions will be pressed tightly against the thawing bucket 31 by the pressure of the thawing fluid entering the thawing bucket 31, achieving a sealing effect. Therefore, when the defrosting container 31 on the bottle fixing part 3 is impacted along the direction of movement, the movable diaphragm 511 facing the water flow will open inward under the force of the water flow, while the movable diaphragm 511 facing away from the water flow will be tightly attached to the defrosting container 31 by the pressure of the defrosting liquid inside the defrosting container 31 to achieve a sealing effect. Thus, by switching the direction of movement of the bottle fixing part 3 back and forth, the opening or sealing of the movable diaphragm 511 in different positions can be changed.

[0031] like Figure 3 As shown, when the defrosting bucket 31 moves to the left, as Figure 4 As shown, at this time, the movable diaphragm 511 on the left side will open inwards towards the inside of the thawing tank 31 under the impact of the thawing fluid. At this time, the water inlet 311 opens, allowing the thawing fluid to enter the thawing tank 31 and thaw the thawing bottle 4. Meanwhile, the movable diaphragm 511 on the right side is tightly adhered to the thawing tank 31 under the pressure of the thawing fluid inside, achieving a sealing effect. Similarly, as... Figure 5As shown, when the thawing tank 31 moves to the right, the movable diaphragm 511 on the right side will open inward under the impact of the thawing fluid's water flow. The thawing fluid can then enter the thawing tank 31 through the inlet 311 to thaw the thawing bottle 4. Figure 6 As shown, the movable diaphragm 511 on the left side is tightly attached to the thawing tank 31 under the pressure of the thawing fluid inside the thawing tank 31 to achieve a sealing effect, and the thawing fluid flows from bottom to top.

[0032] Please refer to Figures 5-8 As shown in this embodiment, it should also be noted that the unidirectional water inlet structure further includes a fixing frame 52, which is also ring-shaped. The outer circumferential surface of the ring-shaped fixing frame 52 is attached to the inner circumferential surface of the fixing diaphragm 51, and the two are connected and fixed. At the same time, the fixing diaphragm 51 and the fixing frame 52 are connected and fixed to the inner circumferential wall of the thawing tank 31 by means of buckles or screws, which is used to protect and limit the movement range of the movable diaphragm 511. In addition, the fixing frame 52 has water inlets 521 whose positions and numbers correspond to the movable diaphragm 511, and the size of the water inlets 521 is larger than the size of the movable diaphragm 511. Therefore, in this embodiment, the use of the fixing frame 52 can play a role in shaping the fixing diaphragm 51 and fixing it to the position of the water inlet 311 in the thawing tank 31. Of course, setting the size of the water inlet 521 to be larger than the size of the movable diaphragm 511 also makes it easy for the water inlet 521 to not interfere when the movable diaphragm 511 is opened inward. This ring arrangement allows for multi-point, uniform unidirectional water inflow. Therefore, in this embodiment, the function of the fixing frame 52 is twofold: first, to press the edge of the fixing diaphragm 51 to fit against the tank wall; and second, its rigidity can maintain the initial shape of the fixing diaphragm 51 and the movable diaphragm 511, preventing them from collapsing and blocking the channel.

[0033] Please refer to Figure 3 As shown, in some embodiments, an elastic element 6 is connected to the inner wall of the defrosting container 31. The elastic element 6 abuts against the defrosting bottle 4. The use of the elastic element 6 can fix the defrosting bottle 4 to follow the rigid movement of the shaking part 2 during the defrosting process, ensuring the shaking effect, improving heat exchange efficiency, and making it convenient to remove when defrosting is completed. In addition, the elastic element 6 can also play a certain buffering role. At the same time, the design of the elastic element 6 can adapt to defrosting bottles 4 of a certain size range, and has good versatility.

[0034] In one example, several elastic elements 6 are provided. These elastic elements 6 are arranged circumferentially along the inner wall of the thawing container 31 and spaced apart along the height direction, so that each position of the thawing bottle 4 has a force point, ensuring that the thawing bottle 4 is subjected to uniform force and has high stability.

[0035] In one example, the elastic element 6 is a silicone pad, silicone bump, or spring sheet, etc. The spring sheet has a simple structure and is easy to use.

[0036] The implementation principle of this embodiment is as follows: Thawing fluid is injected into the storage chamber 1. The thawing bottle 4 is inserted into the thawing bucket 31 of the bottle fixing part 3 with its opening facing upwards. During this process, the elastic element 6 deforms, firmly clamping the thawing bottle 4, forming an annular gap between the outer wall of the thawing bottle 4 and the inner wall of the thawing bucket 31. The drive motor drives the support platform and all the bottle fixing parts 3 on it to perform a reciprocating linear shaking motion in the warm water. During the shaking process, when the thawing bucket 31 moves relative to the water flow, the warm water in the storage chamber 1 exerts pressure on the movable diaphragm 511 at the water inlet 311 on the outside. The pressure difference causes the movable diaphragm 511 to open towards the inside of the thawing bucket 31 (i.e., towards the thawing bottle 4), and warm water flows into the interior of the thawing bucket 31 through the water inlet 311 and the opened movable diaphragm 511. The flowing warm water enters the annular gap from the bottom of the thawing bucket 31 and flows upwards, washing the outer wall of the thawing bottle 4 and performing heat exchange. When the shaking motion reverses or the speed changes, causing a decrease in pressure difference, the movable diaphragm 511 rebounds under its own elasticity or the slight reverse action of the water flow within the gap, closing and covering the water inlet 311, effectively preventing a large amount of water from flowing back out of the annular gap. Through continuous shaking, fresh warm water is continuously pumped in through the one-way water inlet structure, while cold water is continuously replaced and discharged (overflowing from the top of the thawing tank 31), achieving rapid and uniform heating and thawing of the thawing bottle 4.

Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this application should be included within the protection scope of this application.
