[0036] In related technologies, aquatic products are placed directly in refrigerator drawers with water to keep them alive. The products' excrement then flows directly into the drawer. Therefore, to retrieve the aquatic products, the drawer needs to be completely removed from the refrigerator body. However, traditional drawers may have a locking mechanism to prevent them from detaching, making it difficult to disassemble drawers containing water and aquatic products. This disassembly process can also cause water and excrement to splash out. Customizing drawer structures specifically for aquatic products would result in low drawer versatility and increased costs.

[0037] Therefore, this utility model proposes a preservation device, which aims to store water and aquatic products by placing an independent, detachable storage box inside the drawer, facilitating the retrieval and cleaning of aquatic products and improving the user experience. It is understood that the preservation device is applied to refrigeration equipment, which is not limited to a specific type of refrigeration equipment, such as refrigerators, refrigerated trucks, etc. The temperature control of the preservation chamber in the preservation device can be controlled by the temperature control system of the refrigeration equipment, or it can be independently controlled by its own independent temperature control system; the specific temperature control method is not specifically limited here. The structure of the preservation device will be described below by way of embodiments.

[0038] like Figures 1 to 3 As shown, the life-keeping device includes a housing 100, a drawer 200, and a storage box 300.

[0039] An opening 101 is provided on one side of the housing 100; a drawer 200 is inserted into the housing 100 through the opening 101 and forms a storage chamber A with refrigeration and heat preservation functions with the housing 100; a storage box 300 is detachably placed in the drawer 200 for storing water and aquatic products, and the inner cavity of the storage box 300 is connected to the storage chamber A.

[0040] Understandably, the housing 100 has a cavity for installing structures such as drawers 200 and storage boxes 300. One side of the cavity has an opening 101. Drawers 200 can be inserted into the housing 100 through the opening 101 or pulled out from the housing 100 through the opening 101. When the drawer 200 is in the state of blocking the opening 101, the drawer 200 and the housing 100 enclose a survival chamber A. Survival chamber A is a closed heat-insulating cavity. The temperature in survival chamber A can be adjusted according to actual needs. For example, the temperature can be appropriately controlled according to the type of aquatic products, as long as it is suitable for the survival of aquatic products. The specific temperature control settings are not limited here.

[0041] In this embodiment, by providing a detachable storage box 300 in the drawer 200, when it is necessary to preserve aquatic products, the user can pull the storage box 300 out of the preservation chamber A by pulling out the drawer 200, and then take the storage box 300 out of the drawer 200 separately to fill with water and aquatic products; after filling, the storage box 300 is placed in the drawer 200, and the drawer 200 is inserted into the housing 100, so that the storage box 300 containing water and aquatic products is placed together in the preservation chamber A. Since the inner cavity of the storage box 300 is connected to the preservation chamber A, the temperature inside the storage box 300 is the same as the temperature of the preservation chamber A, thereby preserving the aquatic products inside the storage box 300; when the user needs to take out the aquatic products, they can simply pull out the drawer 200 to take out the storage box 300, which is convenient for taking out the aquatic products and cleaning operations. Therefore, there is no need to forcibly remove the drawer 200 from the shell 100, nor is it necessary to make additional structural improvements to the matching structure between the drawer 200 and the shell 100 in the related technology. This can improve both the convenience of taking out and putting in aquatic products and the versatility of the structure.

[0042] The specific detachable method between the storage box 300 and the drawer 200 can be determined according to the actual situation. For example, the storage box 300 can be placed directly on the support surface of the drawer 200, or a positioning groove can be set inside the drawer 200 to install the storage box 300, or a snap-fit ​​structure can be used to attach the storage box 300, as long as it is convenient to put in and take out the storage box 300. The specific structure of the storage box 300 can also be determined according to the actual situation, such as a square box, a cylindrical box, a rectangular box, a triangular box, or some other shape of box structure. Optionally, the storage box 300 can be made of metal, plastic, or glass.

[0043] It should be noted that in practical applications, the preservation device of this embodiment can be installed as a module in a refrigeration device and operate under the control system of the refrigeration device, or it can operate as an independent device. When installed as a module in a refrigeration device (taking a refrigerator as an example), the shell 100 can be the inner shell structure that forms the cold storage compartment in the refrigerator, the drawer 200 is installed in the corresponding compartment, and the storage box 300 is placed in the corresponding drawer 200. In this way, the preservation compartment A can be the compartment formed by the shell 100, and the cooling capacity in the preservation compartment A can be provided and controlled by the refrigerator's own refrigeration system. When operating as an independent device, the shell 100 and the drawer 200 can adopt a heat preservation structure. When the drawer 200 seals the opening 101, the shell 100 and the drawer 200 enclose and form a preservation compartment A with heat preservation function. In this way, an independently operating temperature control system can be set in the preservation device to provide cooling capacity and control the temperature of the preservation compartment A, so as to keep the aquatic products in the storage box 300 in the preservation compartment A alive and fresh.

[0044] In summary, in the preservation device of this utility model, an opening 101 is provided on one side of the shell 100, and the drawer 200 can be inserted into the shell 100 through the opening 101 to form a preservation chamber A with refrigeration and heat preservation functions; by providing a detachable storage box 300 in the drawer 200, when the drawer 200 blocks the opening 101, the storage box 300 is located in the preservation chamber A, and the inner cavity of the storage box 300 is connected to the preservation chamber A, so that the temperature inside the storage box 300 can be maintained. The temperature is consistent with that of the preservation chamber A, enabling the preservation of aquatic products inside the storage box 300. When it is necessary to retrieve or remove aquatic products, simply pull the drawer 200 out of the shell 100, placing the storage box 300 outside the preservation chamber A. The user can then remove the storage box 300 from the drawer 200 for retrieval and cleaning of aquatic products without having to remove the entire drawer 200 from the shell 100, thus avoiding splashing of excrement and water during forceful removal. Therefore, this embodiment improves the convenience of retrieving and removing aquatic products from the preservation device, prevents contamination, and also enhances structural versatility.

[0045] Please see Figure 1 and Figure 2 In one embodiment of this application, the drawer 200 includes a tray 210 and a door 220. The tray 210 is slidably connected to the housing 100, and the storage box 300 is placed on the tray 210. The door 220 is located on the outside of the tray 210 and is used to close or open the opening 101.

[0046] In this embodiment, the tray 210 serves to support the storage box 300 and connect to the housing 100. The tray 210 is slidably connected to the housing 100. Optionally, the tray 210 has slide rails on both sides, and the housing 100 has corresponding slide grooves on both sides. The slide rails and slide grooves cooperate to ensure the smooth pulling of the tray 210 and prevent the tray 210 from falling off the housing 100. The door 220 serves to seal the opening 101, making the living chamber A a relatively sealed chamber. Optionally, the door 220 can be made of thermal insulation material, which can provide thermal insulation for the living chamber A when the opening 101 is sealed.

[0047] The storage box 300 is placed on the tray 210. Understandably, when the drawer 200 is pulled outward, the door 220 can also block the storage box 300 to prevent it from falling off the tray 210.

[0048] To facilitate the retrieval and placement of the storage box 300, in one embodiment of this application, the height of the opposite side walls of the tray 210 is less than or equal to half the height of the storage box 300.

[0049] This design makes it easier for users to reach into the tray 210 to move or place the storage box 300, further improving operational convenience.

[0050] Optionally, the storage box 300 has handles 313 on opposite side walls for the user to apply force. The height of the side walls of the tray 210 is lower than the height of the handles 313.

[0051] Please see Figures 1 to 3 In one embodiment of this application, the storage box 300 includes a box body 310 with an open opening and a cover plate 320. The cover plate 320 covers the open opening and has a plurality of ventilation holes 301 that connect the ventilation chamber A with the inner cavity of the box body 310.

[0052] This embodiment illustrates the structure of the storage box 300. The box body 310 is used to hold water and aquatic products. The cover plate 320 seals the opening and forms a roughly enclosed space with the box body 310, which can prevent water from splashing out of the box body 310 and aquatic products from jumping out, thus ensuring the cleanliness of the storage room A.

[0053] By providing several air passages 301 on the cover plate 320 connecting the preservation chamber A and the inner cavity of the box body 310, the cold air in the preservation chamber A can smoothly enter the inner cavity of the box body 310, ensuring the temperature and air requirements of the aquatic products. Optionally, the air passages 301 can be circular, square, strip-shaped, or other shaped hole structures. Optionally, the number of air passages 301 can be one, two, three, or more. When the number of air passages 301 is more than two, the more than two air passages 301 can be distributed in a matrix-like interval, a ring-array interval, or an irregular scattered interval on the cover plate 320.

[0054] Optionally, the connection between the cover 320 and the box body 310 can be a sliding cover, a flip cover, or a direct snap-fit ​​closing method.

[0055] Of course, in some other embodiments of this application, the storage box 300 may also be a box structure without a cover and with an open opening, and the inner cavity of the box is directly connected to the storage chamber A through the opening.

[0056] Please see Figures 1 to 3 In one embodiment of this application, the top of the housing 100 is provided with a cold air inlet 102 that communicates with the living chamber A, and the cold air inlet 102 is disposed opposite to the cover plate 320.

[0057] Understandably, cold air is heavier than hot air. In this embodiment, by placing the cold air inlet 102 of the keeping chamber A at the top of the housing 100, the cold air flows downward from the top of the keeping chamber A, which is more conducive to filling the entire keeping chamber A with cold air and improving cooling efficiency. The cold air inlet 102 is positioned opposite to the cover plate 320, and the cover plate 320 is provided with several air passage holes 301. This arrangement is more conducive to the entry of cold air into the box 310, further improving the speed of temperature regulation inside the storage box 300.

[0058] Optionally, the housing 100 is provided with a cold air channel communicating with the cold air inlet 102. In practical applications, when the keep-alive device is used in a refrigerator, the cold air channel can be connected to the refrigerator's refrigeration system, and the refrigerator's refrigeration system can be used to deliver cold energy to the keep-alive compartment A. When the keep-alive device is running independently, its own refrigeration system can be set on the keep-alive device and connected to the cold air channel, and its own refrigeration system can be used to deliver cold energy to the keep-alive compartment A.

[0059] Optionally, the housing 100 is provided with a return air vent (not shown) communicating with the keep-alive chamber A. Cold air enters the keep-alive chamber A through the cold air inlet 102 for heat exchange, and the airflow after heat exchange flows out through the return air vent, ensuring pressure balance in the keep-alive chamber A and allowing cold air to enter smoothly. Optionally, the return air vent can be located on the back side of the keep-alive chamber A.

[0060] Please see Figures 1 to 3 In one embodiment of this application, the upper edge of the side wall of the box body 310 away from the outlet 101 is provided with a return air notch 302, which connects the inner cavity of the box body 310 with the living chamber A.

[0061] This design allows the cold air entering the box 310 through the air vent 301 to flow smoothly out through the return air gap 302 into the survival chamber A after heat exchange, ensuring the exchange of cold air and air, and improving the survival rate of aquatic products in the box 310.

[0062] In this embodiment, by setting the return air gap 302 on the upper edge of the side wall of the box body 310 away from the outlet 101, the return air gap 302 is located in the area of ​​the survival chamber A near the back side, which is closer to the return air outlet of the survival chamber A. This allows for faster return air, increases the airflow speed, increases the speed of air exchange in the box body 310, and further improves the survival rate of aquatic products.

[0063] In addition, the return air notch 302 can also serve as a foolproof reminder. When the user places the storage box 300, the side with the return air notch 302 should face inward.

[0064] Optionally, the return air notch 302 can be a perforated structure or a notched groove structure.

[0065] To further extend the shelf life of aquatic products, please refer to [link / reference]. Figures 1 to 3 In one embodiment of this application, the bottom of the box 310 is provided with a grille 311; the grille 311 is provided with a plurality of protrusions.

[0066] In this embodiment, the grille 311 can support and elevate aquatic products, reducing contact between the products and their excrement and improving survival rates. The grille 311 has several protrusions that separate the aquatic products, preventing collisions and reducing waste, thus increasing survival rates.

[0067] Optionally, the grille 311 and the housing 310 can be detachably or non-detachably assembled.

[0068] Alternatively, the grille 311 may be made of plastic.

[0069] To further extend the shelf life of aquatic products, please refer to [link / reference]. Figures 1 to 3 In one embodiment of this application, the side wall of the box 310 is provided with water level scale lines 312.

[0070] Understandably, the amount of water used to keep aquatic products alive should not be too much or too little. The amount of water should be about halfway submerged. In this embodiment, the design of the water level scale 312 reminds users to put in an appropriate amount of water to prevent the survival rate of aquatic products from being affected by too much or too little water.

[0071] To further improve the survival rate of aquatic products, please refer to [link / reference]. Figure 1 In one embodiment of this application, the housing 100 is provided with an ultraviolet sterilization module 400 for ultraviolet sterilization of the storage box 300.

[0072] In this embodiment, by setting the ultraviolet sterilization module 400 to sterilize the storage box 300 with ultraviolet light, bacteria can be reduced and microorganisms on aquatic products can be eliminated, thereby improving the survival rate.

[0073] Optionally, the ultraviolet sterilization module 400 can irradiate the storage box 300 by means of ultraviolet light. In this case, the storage box 300 can be made of a non-transparent material that can transmit ultraviolet wavelengths, or it can be made of a transparent material.

[0074] Optionally, the ultraviolet sterilization module 400 can be installed on the top of the housing 100 to irradiate ultraviolet light from top to bottom, so that the ultraviolet light can cover the entire preservation chamber A.

[0075] In practical applications, when the preservation device is used in a refrigerator, the ultraviolet sterilization module 400 can be electrically connected to the refrigerator's control system, and the operation of the ultraviolet sterilization module 400 can be directly controlled through the refrigerator's control system.

[0076] To further improve the survival rate of aquatic products, please refer to [link / reference]. Figure 1 In one embodiment of this application, a temperature sensor 500 is provided on the housing 100 to detect the temperature inside the preservation chamber A.

[0077] In this embodiment, a temperature sensor 500 is set to detect the temperature inside the keep-alive chamber A, which can monitor the temperature inside the keep-alive chamber A in real time or at regular intervals, thus making it easier to control the temperature inside the keep-alive chamber A.

[0078] Optionally, the temperature sensor 500 can be installed at the top, side, or bottom of the preservation compartment A. When the preservation device is used in a refrigerator, the temperature sensor 500 can be electrically connected to the refrigerator's temperature control system to regulate the temperature inside the preservation compartment A. When the preservation device is an independently operating device, the temperature sensor 500 can be electrically connected to the preservation device's own temperature control system to regulate the temperature inside the preservation compartment A.

[0079] Please see Figure 1 and Figure 2In one embodiment of this application, the housing 100 includes a housing body 110 and a top cover 120. The housing body 110 has a receiving cavity with an opening 101. A drawer 200 is assembled with the housing body 110 to form a preservation chamber A. The top cover 120 is disposed above the housing body 110, and an installation space is formed between the top cover 120 and the upper surface of the housing body 110. The air-cooling channel, ultraviolet sterilization module 400, temperature sensor 500, etc., mentioned in the previous embodiment can all be installed in this installation space. A cold air inlet 102 is located on the top wall of the housing body 110. Optionally, the top cover 120 and the housing body 110 are snap-fitted together.

[0080] This design makes the structure of the life-keeping device more compact. The upper cover 120 can be directly removed to inspect and maintain each module. At the same time, it does not occupy the space of the life-keeping chamber A, thus ensuring the volume.

[0081] This utility model also proposes a refrigeration device, which includes a main body and a life-preserving device. The specific structure of the life-preserving device is as described in the above embodiments. Since this refrigeration device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The main body of the device has a temperature control system, and the life-preserving device is installed on the main body. The temperature control system is used to control the temperature of the life-preserving chamber A.

[0082] Alternatively, the refrigeration equipment can be a refrigerator, a refrigerated truck, etc.

[0083] As an example, taking a refrigerator as an example, the shell 100 can be the inner shell structure that forms the refrigeration compartment in the refrigerator, the drawer 200 is installed in the corresponding compartment, and the storage box 300 is placed in the corresponding drawer 200. In this way, the preservation compartment A can be the compartment formed by the shell 100, and the coldness in the preservation compartment A can be controlled by the refrigerator's temperature control system.

[0084] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
