Abstract
Description
Technical Field
[0001] This utility model relates to the field of defrosting instruments, specifically a defrosting instrument. Background Technology
[0002] Biobanks typically use cryovials to store biological samples, and each cryovial must have a clear, informational label. Given the large amount of information to be labeled on the samples, traditional handwritten labels are insufficient for managing large volumes of samples in biobanks. Cryovials with pre-printed QR codes on the bottom have emerged and are widely used in the biobank field. However, during the transport of biological samples, temperature differences can cause ice crystals and frost to condense on the bottom of the cryovials, covering the QR code and affecting information retrieval. Therefore, a defrosting device is needed to clean them. This involves briefly heating the cryovials on a defrosting device to melt the ice crystals and frost, and to absorb any water droplets.
[0003] Common defrosting devices or methods for cryogenic containers may lack effective temperature control mechanisms during the heating process, resulting in slow heating speeds and uneven temperature distribution on the heated surface, easily leading to significant temperature differences. This slows down the melting of ice crystals and frost, hindering rapid defrosting. Furthermore, these devices or methods struggle to effectively handle the water droplets generated after defrosting, easily leaving residue. Even after the cryogenic container is removed, this residual moisture cannot be promptly removed, affecting the device's performance and condition for subsequent use, thus reducing the overall defrosting quality and failing to meet the operational requirements of a defrosting device. Therefore, a defrosting device is proposed. Utility Model Content
[0004] In view of the shortcomings of the existing technology, this utility model provides a defrosting device to solve the technical problems of slow heating speed and uneven temperature distribution on the heating surface due to the lack of an effective temperature control mechanism.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a defrosting device, comprising:
[0006] The lower housing is fitted with a top cover, and the interior of the lower housing is filled with heat insulation cotton. The upper surface of the heat insulation cotton is covered with an insulating heating film.
[0007] A heat-conducting sheet is laid on the upper surface of an insulating heating film. A heat-conducting silicone is installed on the upper part of the heat-conducting sheet. A friction canvas is laid on the outside of the heat-conducting silicone. A square box station is installed in the middle of the friction canvas.
[0008] A power module is inserted into one side of the lower housing. A control module is inserted into the other side of the lower housing cavity. The control module integrates a temperature sensor. A power switch is installed on the outside of the lower housing. The power switch is connected to the power module through a wire.
[0009] Preferably, the top cover is internally fitted with bolts, the number of which is 4-12 sets. The outer side of the bolts is connected to the corresponding position on the top of the lower housing, which facilitates the disassembly and assembly of the top cover.
[0010] Preferably, a bottom shell is snapped into the lower side of the inner cavity of the lower housing, and the power module and control module are both connected to the inner wall of the lower housing via stands and screws, which facilitates disassembly and assembly.
[0011] Preferably, a high-temperature adhesive is coated between the insulating heating film and the heat-conducting sheet, the upper surface of the heat-conducting silicone has a micro-porous structure, and a display screen is installed on the outside of the control module. The display screen penetrates through the corresponding position inside the lower housing, improving the convenience of using the defrosting device.
[0012] Preferably, a temperature fuse is connected in series between the control module and the insulating heating film. The melting temperature of the temperature fuse is higher than the set temperature threshold of the control module. The temperature fuse is embedded in a preset slot inside the heat insulation cotton, which improves the safety of the defrosting device.
[0013] Preferably, the control module also integrates a timing unit, and the lower housing is equipped with a timing reset button that is electrically connected to the control module. The timing data of the timing unit is synchronously displayed on the display screen.
[0014] Compared with the prior art, the present invention provides a defrosting device with the following beneficial effects:
[0015] This defrosting device, when powered on, converts AC to DC power via a power module to supply power to the control module, causing the insulating heating film to heat up to the set operating temperature range. The integrated temperature sensor within the control module monitors the actual temperature of the target area in real time. When the actual temperature is lower than the set value, the control module outputs a signal to activate the insulating heating film, initiating heating. When the actual temperature reaches or exceeds the set value, the control module outputs a signal to deactivate the insulating heating film, stopping heating. Thus, after the cryopreservation box is placed at the designated location, the insulating heating film heats up rapidly and maintains a uniform and stable heating surface, quickly melting ice crystals and frost, and absorbing water droplets. Once the equipment temperature is constant and the cryopreservation box is removed, the continuously heated insulating heating film absorbs residual moisture on the equipment surface and evaporates it, improving the defrosting device's performance. The added insulating heating film also enhances heating uniformity, preventing temperature differences during defrosting. Attached Figure Description

[0022] 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.
[0023] This utility model provides a technical solution: a defrosting device, comprising a lower housing 1, a top cover 2, bolts 3, heat insulation cotton 4, an insulating heating film 5, a heat-conducting sheet 6, heat-conducting silicone 7, a friction canvas 8, a square box station 9, a power module 10, a control module 11, a power switch 12, a bottom housing 13, and a display screen 14.
[0024] Please see Figure 1 The lower housing 1 is fitted with a top cover 2. Please refer to [link / reference]. Figure 3 The lower housing 1 is fitted with heat insulation cotton 4, and the upper surface of the heat insulation cotton 4 is covered with an insulating heating film 5. Please refer to [link / reference]. Figure 2 Bolts 3 are inserted inside the top cover 2. There are 4-12 sets of bolts 3. The outside of the bolts 3 is connected to the corresponding position on the top of the lower housing 1.
[0025] Please see Figure 3 A heat-conducting sheet 6 is laid on the upper surface of the insulating heating film 5. A heat-conducting silicone 7 is installed on the upper part of the heat-conducting sheet 6. A friction canvas 8 is laid on the outside of the heat-conducting silicone 7. A square box station 9 is installed in the middle of the friction canvas 8.
[0026] Please see Figure 4 The power module 10 is inserted into one side of the inner casing 1. Please refer to [link / reference]. Figure 5 A control module 11 is inserted into the other side of the inner cavity of the lower housing 1. The control module 11 integrates a temperature sensor. A power switch 12 is installed on the outside of the lower housing 1. The power switch 12 is connected to the power module 10 through a wire. A bottom shell 13 is snapped into the lower side of the inner cavity of the lower housing 1. The power module 10 and the control module 11 are both connected to the inner wall of the lower housing 1 through a bracket and screws.
[0027] By turning on the power switch 12, the power module 10 converts AC power to DC power to supply the control module 11, causing the insulating heating film 5 to heat up to the set operating temperature range. The temperature sensor integrated inside the control module 11 monitors the actual temperature of the target area in real time. When the actual temperature is lower than the set value, the control module 11 outputs a signal to connect the insulating heating film 5 and start heating. When the actual temperature reaches or exceeds the set value, the control module 11 outputs a signal to disconnect the insulating heating film 5 and stop heating. Thus, after the cryopreservation box is placed at the square box station 9, the insulating heating film 5 heats up quickly and maintains a uniform and stable heating surface, which can quickly melt ice crystals and frost and absorb water droplets. When the equipment temperature is constant and the cryopreservation box is removed, the continuously heated insulating heating film 5 can absorb residual moisture on the equipment surface and evaporate it, improving the quality of the defrosting device. At the same time, the added insulating heating film 5 improves the uniformity of heating and avoids temperature differences during the defrosting process.
[0028] A high-temperature adhesive is coated between the insulating heating film 5 and the heat-conducting sheet 6. The upper surface of the heat-conducting silicone 7 has a micro-porous structure. A display screen 14 is installed on the outside of the control module 11. The display screen 14 penetrates the corresponding position inside the lower housing 1. A temperature fuse is connected in series between the control module 11 and the insulating heating film 5. The melting temperature of the temperature fuse is higher than the set temperature threshold of the control module 11. The temperature fuse is embedded in the preset slot inside the heat insulation cotton 4. A timing unit is also integrated inside the control module 11. A timing reset button electrically connected to the control module 11 is installed on the outside of the lower housing 1. The timing data of the timing unit is synchronously displayed on the display screen 14.
[0029] This solution converts AC power to DC power via power module 10 by turning on power switch 12, supplying power to control module 11. This allows the insulating heating film 5 to heat up to the set operating temperature range. The temperature sensor integrated inside control module 11 monitors the actual temperature of the target area in real time. When the actual temperature is lower than the set value, control module 11 outputs a signal to connect the insulating heating film 5 and start heating. When the actual temperature reaches or exceeds the set value, control module 11 outputs a signal to disconnect the insulating heating film 5 and stop heating. Thus, after the cryopreservation box is placed at the square box station 9, the insulating heating film 5 heats up rapidly and maintains a uniform and stable heating surface, quickly melting ice crystals and frost and absorbing water droplets. When the equipment temperature is constant and the cryopreservation box is removed, the continuously heated insulating heating film 5 absorbs residual moisture on the equipment surface and evaporates it, improving the quality of the defrosting device. At the same time, the added insulating heating film 5 improves the uniformity of heating and avoids temperature differences during the defrosting process.
