Description

Technical Field

[0001] This utility model relates to the field of outdoor backpack technology, and in particular to a bag with an external cooling device. Background Technology

[0002] When people go out, they often need to carry a lot of supplies and food, including but not limited to snacks, drinking water, supplies, spare clothes, etc. Some snacks need to be stored at low temperatures. In hot environments, drinking water can be cooled down before drinking. When taking infants out, breast milk also needs to be stored at low temperatures to prevent it from spoiling very easily at room temperature.

[0003] To meet these needs, people carry low-temperature preservation products such as thermos cups and thermos bottles when they go out. This not only increases the number of items that need to be carried, but also increases the size and weight of these items, requiring bags with very large capacity to hold all the items and food.

[0004] Furthermore, the variety and complexity of items inside the bag—from snacks, drinking water, toiletries, spare clothes, breast milk to diapers and toys—not only takes up a lot of space but also makes accessing items extremely inconvenient. Finding a specific item often requires considerable time and effort rummaging through the bag, further increasing the burden and inconvenience when traveling. Therefore, how to rationally plan and organize these items and food has become an important issue that people need to address when going out. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a bag with an external cooling device. The baby bag mainly consists of three parts: the bag, the insulated cylinder, and the cooling component. The insulated cylinder is designed to be detachable and can be easily installed at the bottom of the bag. The cooling component is cleverly placed inside the insulated cylinder, and its main function is to provide a cooling effect to the cavity of the insulated cylinder, ensuring that the cavity maintains a low temperature environment.

[0006] According to some embodiments of this utility model, the specific structure of the heat preservation cylinder includes three parts: an outer shell, a cap, and an inner liner. The outer shell is designed to be installed at the bottom of the bag, and the cap is installed at the opening of the outer shell to ensure airtightness. Inside the outer shell, a cooling component and an inner liner are sequentially installed. The bottom of the inner liner is in close contact with the cooling component. The cooling component creates a stable low-temperature environment inside the inner liner through its cooling effect, which is very suitable for low-temperature preservation of breast milk.

[0007] According to some embodiments of this utility model, during the operation of the refrigeration component, a large amount of heat is generated due to the refrigeration principle. In order to effectively reduce the temperature, multiple heat dissipation holes are specially designed in the lower part of the outer shell wall. These heat dissipation holes surround the refrigeration component to ensure that the heat can be dissipated in time and avoid overheating.

[0008] According to some embodiments of this utility model, in order to further reduce temperature fluctuations in the inner liner, the insulated cylinder is also specially equipped with an insulated sleeve; the insulated sleeve is placed on the outside of the inner liner and is sandwiched between the inner wall of the outer cylinder shell and the outer wall of the inner liner. In this way, the insulated sleeve can effectively reduce the loss of cold energy, thereby extending the preservation time of breast milk.

[0009] According to some embodiments of this utility model, the refrigeration component mainly consists of three parts: a thermoelectric cooler, a heat sink, and a cooling fan. The thermoelectric cooler is attached to the bottom of the inner liner, the heat sink is attached to the bottom of the thermoelectric cooler, and the cooling fan is installed at the bottom of the heat sink. When the thermoelectric cooler starts working, its cold end contacts the inner liner, and its hot end contacts the heat sink. Heat is transferred to the heat sink through conduction, and the cooling fan blows cold air towards the heat sink, completing the heat dissipation process. Under normal circumstances, the temperature difference between the cold and hot ends of the thermoelectric cooler can reach between 10°C and 20°F. Cold air enters through the heat dissipation holes and is then blown towards the hot end by the cooling fan, thereby effectively reducing the temperature of the hot end, which in turn lowers the temperature of the cold end, achieving a lower cooling effect.

[0010] According to some embodiments of this utility model, the outer shell is structurally designed as a first shell, a second shell, and a bottom shell connected in sequence. This split structure design allows for easy disassembly of the second shell to expose the refrigeration component and facilitate maintenance if a malfunction occurs during subsequent use.

[0011] According to some embodiments of this utility model, the first housing is provided with a bottle mouth, and a cylindrical cap is installed at the bottle mouth via threads. The lower part of the second housing has multiple heat dissipation holes arranged to ensure effective heat dissipation. In this embodiment, the first and second housings, as well as the second housing and the bottom housing, are connected by snap-fit ​​connections, which are both secure and easy to disassemble. Of course, threaded connections can also be used between the first and second housings, and between the second housing and the bottom housing, providing more connection options.

[0012] According to some embodiments of this utility model, in order to facilitate the installation of the insulation tube, a sleeve position is specially designed at the bottom of the bag, and the insulation tube can be easily inserted into the sleeve position.

[0013] According to some embodiments of this utility model, in this embodiment, two pieces of packaging are sewn to the bottom of the bag. These two pieces of packaging overlap each other to form a sleeve position with an enclosing structure, and the two pieces of packaging are connected by Velcro, which makes it convenient for users to adjust and fix the position of the heat preservation tube as needed.

[0014] According to some embodiments of this utility model, a power supply is specially installed inside the bag. This power supply is connected to the cooling component via a power cord to provide a stable power supply to the cooling component. The power supply is designed to be rechargeable, allowing users to easily replenish the power at any time during use, ensuring that the cooling component can work continuously and maintain the freshness of the breast milk.

[0015] This utility model has at least the following beneficial effects: 1. In actual use, users can neatly place various items such as diapers, wipes, clothing, and snacks inside the bag, while placing food requiring low-temperature preservation, drinking water, and breast milk storage bags or bottles inside the insulated container. By activating the built-in cooling component of the insulated container, efficient and continuous cooling is achieved, maintaining a consistently low and stable environment inside the container. This effectively preserves food, cools drinking water, and keeps breast milk fresh, significantly extending its shelf life. Furthermore, the external design of the insulated container, cleverly installed at the bottom of the bag, not only cleverly reduces the space occupied inside the bag, avoiding overcrowding, but also greatly increases the overall capacity of the bag, allowing users to carry more baby supplies and meet diverse needs when out and about.

[0016] 2. A cold storage box is installed at the bottom of the inner cavity of the inner liner. The cold storage box can maintain a stable low temperature environment inside the cylinder cavity even when the refrigeration components are not working.

[0017] 3. To further enhance user convenience, a sleeve position matching the size of the insulated tube is specially designed at the bottom of the bag. The insulated tube can be easily inserted into the sleeve position. The installation process is simple and quick, without complicated operating steps, ensuring that users can quickly and easily install and remove the insulated tube during use, thus improving the overall convenience and user experience.

[0022] Reference Figures 1 to 4 As shown in Figures 9 and 10, a bag with an external cooling device is provided. The baby bag mainly consists of three parts: a bag 100, an insulated cylinder 200, and a cooling component 300. The insulated cylinder 200 is designed to be detachable and can be easily installed at the bottom of the bag 100. The cooling component 300 is cleverly placed inside the insulated cylinder 200, and its main function is to provide a cooling effect to the cavity of the insulated cylinder 200 to ensure that the cavity maintains a low temperature environment.

[0023] In practical use, users can neatly place various items such as diapers, wipes, clothing, and snacks inside the bag 100, while the insulated container 200 contains food requiring low-temperature preservation, drinking water, and breast milk storage bags or bottles. By activating the built-in cooling component of the insulated container 200, efficient and continuous cooling is achieved, maintaining a consistently low and stable environment inside the container. This effectively preserves food, cools drinking water, and keeps breast milk fresh, significantly extending its shelf life. Furthermore, the external design of the insulated container 200, cleverly installed at the bottom of the bag 100, not only minimizes the space occupied inside the bag 100, avoiding overcrowding, but also greatly increases the overall capacity of the bag 100, allowing users to carry more baby supplies and meet diverse needs when out and about.

[0024] Reference Figure 5 , 6 As shown, the insulation cylinder 200 comprises three parts: an outer shell 210, a lid 220, and an inner liner 230. The outer shell 210 is designed to be installed at the bottom of the bag 100, while the lid 220 is installed at the opening of the outer shell 210 to ensure a tight seal. Inside the outer shell 210, a refrigeration unit 300 and an inner liner 230 are sequentially installed. A cold storage box 500 is installed at the bottom of the inner cavity of the inner liner 230, and the bottom of the inner liner 230 is in contact with the refrigeration unit 300. The refrigeration unit 300, through its cooling effect, creates a stable low-temperature environment inside the inner liner 230, which is very suitable for low-temperature storage.

[0025] Reference Figure 7 As shown, during the operation of the refrigeration component 300, a large amount of heat is generated due to the refrigeration principle. In order to effectively reduce the temperature, multiple heat dissipation holes 214 are specially designed on the lower part of the outer shell 210. These heat dissipation holes 214 surround the refrigeration component 300 to ensure that the heat can be dissipated in time and avoid overheating.

[0026] Reference Figure 5 , 7 As shown, in order to further reduce temperature fluctuations in the inner liner 230, the insulation cylinder 200 is also specially equipped with an insulation sleeve 240; the insulation sleeve 240 is fitted over the outer side of the inner liner 230 and is sandwiched between the inner wall of the outer cylinder shell 210 and the outer wall of the inner liner 230. In this way, the insulation sleeve 240 can effectively reduce the loss of cold energy, thereby extending the preservation time.

[0027] Reference Figure 5 , 7As shown, specifically, the cooling assembly 300 mainly consists of three parts: a thermoelectric cooler 310, a radiator 320, and a cooling fan 330. The thermoelectric cooler 310 is in contact with the bottom of the inner liner 230, while the radiator 320 is in close contact with the bottom of the thermoelectric cooler 310. The cooling fan 330 is installed below the radiator 320 and fixed to the bottom of the outer shell 210. When the thermoelectric cooler 310 starts working, its cold end is in contact with the inner liner 230, and its hot end is in contact with the radiator 320. Heat is transferred to the radiator 320 through conduction, and the cooling fan 330 blows cold air toward the radiator 320 to complete the heat dissipation process.

[0028] Reference Figure 5 As shown, the cold energy generated by the semiconductor cooling chip 310 is simultaneously transferred to the cold storage box 500 and the inner liner 230. The cold storage box 500 absorbs and stores the cold energy, thereby creating a stable low-temperature environment inside the inner liner 230. At the same time, when the cooling components are not working, the cold storage box 500 slowly releases the cold energy, extending the cold-keeping time of the inner liner 230. Alternatively, the cold storage box 500 can be placed in the refrigerator for pre-cooling before being placed in the inner liner 230 to release the cold energy for use.

[0029] Reference Figure 7 The cold storage box 500 includes a box cover 510 and a box body 520. The box cover 510 is fastened onto the box body 520 and the box cover 510 and the box body 520 are fastened together by screws. A sealing ring 530 is installed on the top of the box body 520. The box cover 510 presses the sealing ring 530 to strengthen the sealing of the inner cavity of the box body 520.

[0030] The cold storage agent is based on the principle of latent heat energy storage by phase change. It maintains the local low temperature environment by absorbing and storing cold energy at low temperature and releasing cold energy at high temperature. In this embodiment, the cold storage agent can be a liquid of SAP polymer resin and water, water, pure water, etc.

[0031] Reference Figure 8 To ensure that the heat sink can be in close contact with the semiconductor cooling chip 310, the bottom of the heat sink 320 is equipped with a bracket 340. The bracket 340 is used to support the heat sink 320. To fix the bracket 340, the inner wall of the outer shell 210 is provided with a fixing buckle 213, and the side of the bracket 340 is fastened to the fixing buckle 213.

[0032] Under normal circumstances, the temperature difference between the cold end and the hot end of the thermoelectric cooler 310 can reach between 40 and 65 degrees Celsius. Cold air enters through the heat dissipation hole 214 and is then blown towards the hot end by the cooling fan 330, thereby effectively reducing the temperature of the hot end and consequently lowering the temperature of the cold end, achieving a lower cooling effect.

[0033] Specifically, the outer shell 210 includes a first shell 211 connected in sequence and a bottom shell 212 snapped into the first shell 211; the first shell 211 is provided with a bottle mouth 2111, and a cylinder cap 220 is threaded onto the bottle mouth 2111; a plurality of heat dissipation holes 214 are arranged in the lower part of the first shell 211 to ensure heat dissipation effect. The outer shell 210 can also be designed to be detachable. The outer shell 210 is designed to consist of a first shell 211, a second shell, and a bottom shell 212 connected in sequence. This allows the second shell to be disassembled to expose the refrigeration component 300 if it malfunctions during subsequent use, making maintenance easier.

[0034] Specifically, the first housing 211 has a bottle mouth 2111, which is fitted with a cap 220 via threads. The lower part of the second housing has multiple ventilation holes 214 arranged to ensure effective heat dissipation. In this embodiment, the first housing 211 and the second housing, as well as the second housing and the bottom housing 212, are connected by snap-fit ​​connections, which are both secure and easy to disassemble. Of course, threaded connections can also be used between the first housing 211 and the second housing, and between the second housing and the bottom housing 212, providing more connection options.

[0035] Reference Figure 2 , 9 As shown in Figure 10, a sleeve position 101 is specially designed at the bottom of the bag 100 to facilitate the installation of the heat insulation cylinder 200. The heat insulation cylinder 200 can be easily inserted into the sleeve position 101. In this embodiment, two cover pieces 110 are sewn to the bottom of the bag 100. These two cover pieces 110 overlap each other to form a sleeve position 101 with an enclosing structure. The two cover pieces 110 are connected by Velcro, which allows the user to adjust and fix the position of the heat insulation cylinder 200 as needed.

[0036] Reference Figure 1 Inside the bag 100, a power supply 400 is also installed. This power supply 400 is connected to the cooling component 300 via a power cord to provide a stable power supply to the cooling component 300. The power supply 400 is designed to be rechargeable, allowing users to easily replenish the power during use and ensuring that the cooling component 300 can continue to operate.
