Description

Technical Field

[0001] The utility model belongs to the field of disinfection cabinets, and particularly relates to a mother and baby disinfection cabinet with double air ducts for internal and external circulation. Background Art

[0002] The main disinfection methods used in maternal and infant sterilizers include ultraviolet (UV) disinfection, high-temperature disinfection, ozone disinfection, and plasma disinfection. UV disinfection uses ultraviolet light to destroy the DNA or RNA molecules in microbial cells, denaturing proteins and achieving a sterilizing effect. Its advantages are high efficiency, rapidity, broad-spectrum sterilization, and no secondary pollution to the environment. High-temperature disinfection uses high temperatures to kill microorganisms such as bacteria and viruses. Its advantages are ease of use and intuitive sterilization. Ozone disinfection utilizes the strong oxidizing properties of ozone to kill microorganisms, while plasma disinfection utilizes the active ingredients in plasma to kill microorganisms. These diverse disinfection methods have led to the development of maternal and infant sterilizers becoming more diverse, intelligent, and efficient. The continued development and application of these technologies will further enhance the performance and user experience of maternal and infant sterilizers, ensuring the hygiene and safety of infant products.

[0003] Existing maternal and infant sterilizers generally use an external circulation method, whereby a fan draws air in from the outside, heats it through a PTC, and then flows into the cavity to work, before exiting through an air outlet. This method cannot ensure uniform airflow circulation within the cavity, resulting in different temperatures and humidity levels at different locations within the cavity, affecting the overall sterilization effect. Furthermore, maternal and infant sterilizers primarily serve baby products, and their cabinets are relatively small. Therefore, the arrangement of the fan and air duct within the limited space is crucial. Furthermore, it is also necessary to ensure the independence of the fan control to prevent the air duct from occupying too much space. Implementing and optimizing the integrated design of the fan and air duct is a current challenge. Summary of the Invention

[0004] In response to the problems in the related technology, the present invention proposes a mother and baby disinfection cabinet with dual air ducts and internal and external circulation. Two fans and internal circulation air ducts are arranged on the same panel on the outside of the cabinet, so as to form internal and external dual circulation airflow in a small-volume mother and baby disinfection cabinet, improve the uniformity and stability of gas circulation, and improve the efficiency and effect of disinfection.

[0005] The utility model is achieved in this way:

[0006] A dual-duct internal and external circulation maternal and infant sterilization cabinet comprises a cabinet body with an opening on one side and a cabinet door hinged to the cabinet opening, wherein an external air inlet and an external air outlet are respectively provided in the cabinet body, the external air inlet is connected to a first fan, and the external air outlet is communicated with the outside;

[0016] Preferably, a sealed cavity is provided at the position where the inner circulation air duct connects with the inner air outlet; and a sealing member is provided between the sealed cavity and the inner air outlet.

[0017] Specifically, the sealing member is a sealing ring or a sealing strip.

[0018] Setting up a sealed chamber can improve the efficiency of gas entering the sealed chamber from the inner air outlet. Cooperating with the action of the second fan, a pressure difference is formed between the sealed chamber and the inside of the cabinet, which accelerates the gas flow, increases the air circulation speed inside the cabinet, and achieves better disinfection and dehumidification effects.

[0019] Preferably, the first fan is located near the middle of the cabinet, the second fan is located on one side of the first fan, and the second fan is arranged at a position where the internal circulation air duct is connected to the internal air inlet.

[0023] Preferably, the corresponding positions of the vent holes are covered with an air plate, and the air plate is provided with a plurality of through holes corresponding to the positions of the vent holes, and the air plate is adjacent to the external air outlet.

[0024] Specifically, setting up an air plate with through holes can control the gas flow. The air plate is close to the external air outlet to facilitate the discharge of gas. The inflow of gas is sent into the cabinet through the first fan. The external air outlet is close to the outside, which can balance the stability of the airflow and make the internal and external airflow circulation more uniform and stable.

[0025] Preferably, the first fan is provided with a heating component, and the second fan is not provided with a heating component.

[0026] Specifically, the heating component may be a PTC heating plate or a PTC heating block.

[0027] The first fan heats the gas and then delivers it into the cabinet, while the second fan directly draws the heated gas in the cabinet into the internal circulation duct and then delivers it back into the cabinet, thus forming an internal and external double circulation, avoiding excessive gas temperature, saving energy, and ensuring uniform and stable airflow.

[0028] Preferably, the first fan and the second fan rotate simultaneously, or the first fan and the second fan rotate alternately.

[0029] Specifically, the first fan and the second fan can work simultaneously or alternately, and each can be controlled independently, thereby forming different circulating airflows.

[0030] Compared with the prior art, the present invention achieves the following beneficial effects:

[0031] The utility model provides a dual-duct, internal-external circulation maternal and infant sterilizer. A first fan, a second fan, and an internal circulation duct are located on the outside of the cabinet. Both ends of the internal circulation duct are connected to the cabinet, and the second fan is connected to the internal circulation duct. The first fan transports external air into the cabinet, while the second fan draws air from the cabinet into the internal circulation duct and recirculates it back into the cabinet. This creates a dual internal-external circulation airflow, improving the uniformity and stability of air circulation within the cabinet. This accelerated air flow also enhances dehumidification and drying efficiency. The dual internal-external circulation airflow can more effectively control internal temperature and humidity conditions, improving disinfection efficiency and effectiveness. The structural design of arranging the first fan, second fan, and internal circulation duct on one side of the cabinet optimizes internal space utilization and facilitates electrical control wiring. This design avoids the air duct from occupying excessive internal space, allowing more items to be sterilized and dried simultaneously. Optimizing space utilization is particularly important for small maternal and infant sterilizers, as it ensures maximum sterilization and drying capacity within a limited volume. The dual internal-external circulation duct design also helps reduce noise and energy consumption. By optimizing the air duct layout and air flow path, the operating noise and energy consumption of the fan can be reduced, greatly improving the performance of the disinfection cabinet and the user experience and comfort.
