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.

[0015] In existing technologies, traditional freezers usually need to be connected to a fixed power source to operate. Once disconnected from the fixed power source, they cannot maintain the internal low-temperature environment, which greatly limits their usage scenarios and flexibility. In some outdoor activities, temporary stalls, or areas with unstable power supply, traditional freezers often cannot work properly and cannot meet the diverse needs of users.

[0016] In view of this, the present invention provides a portable electric freezer. Through the cooperation of the base, shell, back panel, inner partition, HIPS injection molded inner liner, freezer top cover, blister-formed inner liner, removable battery, compressor, condenser, controller and freezer thermostat, the removable battery powers the freezer's refrigeration system, enabling the freezer to operate normally without a fixed power source. This provides users with a reliable low-temperature storage solution, meeting the diverse usage needs of outdoor activities, temporary stalls and other scenarios, and greatly expanding the freezer's application scenarios and flexibility.

[0017] Depend on Figure 1-5It is known that a portable electric freezer includes a base 1, a shell 2 fixedly connected to the top of the base 1, a back plate 3 fixedly connected to the back of the shell 2, an inner partition 4 fixedly connected to the inside of the shell 2, a HIPS injection-molded inner liner 5 disposed above the inner partition 4 inside the shell 2 and the back plate 3, a freezer top cover 6 rotatably connected to the top of the back plate 3, a blister-formed inner liner 7 disposed at the bottom of the freezer top cover 6, a removable battery 8 disposed on one side below the inner partition 4, a compressor 9 fixedly connected to the top of the base 1 on one side of the removable battery 8, a condenser 10 connected to one side of the compressor 9, a controller 11 fixedly connected to the top of the base 1 on one side of the compressor 9, and a freezer thermostat 12 disposed at the bottom of the front of the shell 2. The removable battery 8, the compressor 9 and the freezer thermostat 12 are all connected to the controller 11. In the specific implementation process, it is worth noting that the outer shell structure of the freezer is formed by the cooperation between the base 1, the shell 2, and the back panel 3. Made of ABS plastic or aluminum alloy, this ensures the stability and durability of the overall structure, allowing it to withstand certain external impacts without easily being damaged. The inner partition 4 divides the interior of the freezer into two independent spaces, with the HIPS injection-molded inner liner 5 positioned above it for freezing or refrigerating food. A polyurethane foam insulation layer is filled between the HIPS injection-molded inner liner 5 and the shell 2, back panel 3, and inner partition 4, effectively insulating external heat, reducing cold loss, and improving the freezer's cooling efficiency. The insulation performance is improved, thereby reducing energy consumption and extending battery life. Through the cooperation between the back panel 3, the freezer top cover 6, and the blister-formed inner liner 7, the freezer top cover 6 is connected to the back panel 3 via hinges. The blister-formed inner liner 7 cooperates with the HIPS injection-molded inner liner 5. When the freezer top cover 6 is closed, the blister-formed inner liner 7 seals the HIPS injection-molded inner liner 5. The overall height of the freezer is approximately 70cm, forming a relatively sealed storage space inside the HIPS injection-molded inner liner 5, effectively preventing cold air leakage and ensuring a stable low-temperature environment inside the freezer. The removable battery 8 uses a battery pack composed of 16 33140 lithium iron phosphate cells connected in series, with a capacity of over 15Ah. When disconnected from a fixed power source, it provides a 48V input voltage for the freezer. The freezer provides continuous and stable power support and features a removable design, allowing users to easily replace or charge the battery according to actual usage. Through the cooperation of the inner partition 4, the removable battery 8, the compressor 9, the condenser 10, and the controller 11, the compressor 9 operates under the control of the controller 11, compressing the refrigerant into a high-temperature, high-pressure gas. The refrigerant then enters the condenser 10 for heat dissipation, becoming a low-temperature, high-pressure liquid. This low-temperature, high-pressure liquid then passes through a throttling device to reduce its pressure before entering the evaporator, which is attached to the outside of the HIPS injection-molded inner liner 5. It absorbs heat, lowering the temperature inside the HIPS injection-molded inner liner 5, thus achieving a cooling effect. The freezer thermostat 12 is used to monitor and regulate the internal temperature of the freezer in real time, allowing users to adjust the temperature according to actual needs. The required temperature value is set by the freezer thermostat 12. The freezer system works in conjunction with the base 1, shell 2, back panel 3, inner partition 4, HIPS injection molded inner liner 5, freezer top cover 6, blister-formed inner liner 7, removable battery 8, compressor 9, condenser 10, controller 11, and freezer thermostat 12. The removable battery 8 powers the freezer's refrigeration system, allowing the freezer to operate normally without a fixed power source. This provides users with a reliable low-temperature storage solution, meeting the diverse needs of outdoor activities, temporary stalls, and other scenarios, greatly expanding the freezer's application scenarios and flexibility. The specific models of the compressor 9, controller 11, and freezer thermostat 12 are not limited, as long as they meet the usage requirements. Furthermore, a battery limiting seat 13 is provided on the top side of the base 1 away from the compressor 9. The battery limiting seat 13 is connected to the removable battery 8. A battery outlet 14 is provided on the bottom side of the outer wall of the back plate 3. The battery outlet 14 is correspondingly provided to the removable battery 8. A battery compartment cover 15 is connected to the inner wall of the battery outlet 14. In the specific implementation process, it is worth noting that the battery limiting seat 13 provides a stable installation position for the removable battery 8, ensuring that it will not shake or shift during the operation of the freezer, thus guaranteeing the safety of use. The battery compartment cover 15 is tightly fitted with the battery outlet 14 through a snap-fit ​​mechanism, making it easy to open for battery replacement or charging operations. At the same time, an external power cord through hole is provided. Through the cooperation between the base 1, the removable battery 8, the battery limiting seat 13, the battery outlet 14, and the battery compartment cover 15, the removable battery 8 can be pulled out from the top of the battery limiting seat 13 by opening the battery compartment cover 15. After disconnecting the power connection cable, the removable battery 8 can be pulled out from the freezer for charging or replacement operations. No complicated tools or professional skills are required, allowing users to easily complete the battery charging work and improving the convenience of using the freezer. Furthermore, a photovoltaic input interface 16 is provided on the side of the removable battery 8 near the battery outlet 14, a DC input interface 17 is provided on the side of the removable battery 8 near the photovoltaic input interface 16, and a DC output interface 18 is provided on the side of the removable battery 8 away from the photovoltaic input interface 16. The photovoltaic input interface 16, the DC input interface 17 and the DC output interface 18 are all electrically connected to the removable battery 8. In the specific implementation process, it is worth noting that the photovoltaic input interface 16, DC input interface 17, and DC output interface 18 are all connected to the BMS battery control board inside the battery pack. The photovoltaic input interface 16 can be connected to a solar photovoltaic panel, which can convert solar energy into electrical energy and charge the removable battery 8 in a sunny outdoor environment. This makes full use of clean energy, reduces dependence on traditional fixed power sources, and further improves the convenience and sustainability of the freezer in outdoor and other scenarios without fixed power sources. The DC input interface 17 can be connected to an external DC power source or connected to a fixed power source through a DC regulated power supply. It can directly power the freezer and charge the removable battery 8, increasing the options for charging the freezer and improving the flexibility of use. The DC output interface 18 can be used to power other DC-powered devices, such as charging mobile phones, lights, etc., during outdoor activities, improving the practicality and added value of the freezer. The specific models of the photovoltaic input interface 16, DC input interface 17, and DC output interface 18 are not limited, as long as they meet the usage requirements. Furthermore, the top of the HIPS injection-molded inner liner 5 is provided with a sealing silicone strip 19, and the freezer top cover 6 is connected to the sealing silicone strip 19. In the specific implementation process, it is worth noting that the sealing silicone strip 19 has good elasticity and sealing performance. When the freezer top cover 6 is closed, the bottom edge of the freezer top cover 6 will be tightly pressed against the sealing silicone strip 19, forming an effective sealing barrier. This can greatly reduce the leakage of cold air inside the freezer and effectively prevent the entry of hot air from the outside, thereby better maintaining the low temperature environment inside the freezer. At the same time, the sealing silicone strip 19 can also play a certain buffering role, reducing the impact force when the freezer top cover 6 is closed. Furthermore, ventilation openings 20 are provided on the bottom sides of the housing 2 and the bottom of the outer wall of the back plate 3, and ventilation grilles 21 are provided on the outer side of the ventilation openings 20. In the specific implementation process, it is worth noting that through the cooperation between the shell 2, back panel 3, vent 20 and ventilation grille 21, a reasonable ventilation channel is formed on the bottom sides and back of the freezer. This ensures that the heat generated by components such as the removable battery 8, compressor 9 and condenser 10 can be dissipated in a timely and effective manner during the operation of the freezer, avoiding heat accumulation inside the freezer, thereby ensuring the cooling effect and stable performance of the freezer.
