Description

Technical Field

[0001] This utility model relates to a sterilization device for maternal and infant products, and in particular a high-efficiency and energy-saving maternal and infant sterilization and drying cabinet. Background Technology

[0002] Baby sterilizers and dryers are devices specifically designed for sterilizing and drying baby products (such as bottles, nipples, tableware, toys, etc.). They can effectively kill bacteria and viruses, keep items dry, and prevent mold growth. However, existing baby sterilizers and dryers have the following problems: (1) During the drying and sterilization process, fresh air is continuously introduced, heated, and then introduced into the cabinet. The air inside the cabinet is constantly pushed out of the cabinet. The warm air entering the cabinet only has brief contact with the items being dried, or even no contact at all, before being discharged, resulting in low drying efficiency and low energy efficiency. (2) The cabinet is always connected to the outside, making it easy for it to come into contact with polluted air outside. Utility Model Content

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0032] Example 1, see Figures 1 to 9 As shown, a high-efficiency and energy-saving maternal and infant sterilization and drying cabinet includes a cabinet body 1, a cabinet door 2, a warm air drying mechanism 19 and a sterilization module 16 installed on the cabinet body 1. The cabinet body 1 has a storage cavity 97, which contains a temperature sensor 20 and a shelf 12. The storage cavity 97 has an exhaust port 11. The warm air drying mechanism 19 has an air outlet 14 and an air inlet 10. The air outlet 14 is connected to the storage cavity 97. The sterilization module 16 is installed in the storage cavity 97 or in a position connected to the storage cavity 97. The air inlet 10 of the warm air drying mechanism 19 is selectively connected to the outside or the storage cavity 97 through an air duct device 6. The exhaust port 11 is selectively connected to or isolated from the outside through an air valve device 60.

[0033] This is a more specific technical solution of the present invention.

[0034] The air duct device 6 includes a circulation channel 61, a first air valve 64, a second air valve 66, a first air valve drive assembly 7, and a second air valve drive assembly. The first end 67 of the circulation channel 61 is connected to the air inlet 10 of the warm air drying mechanism 19, the second end 63 of the circulation channel 61 is connected to the outside, and the third end 68 of the circulation channel 61 is connected to the storage cavity 97. The first air valve drive assembly 7 drives the first air valve 64 to open or close the second end 63 of the circulation channel 61, and the second air valve drive assembly drives the second air valve 66 to open or close the third end 68 of the circulation channel 61.

[0035] As a further embodiment, the damper device 60 is located at the fourth end 62 of the circulation channel 61, the fourth end 62 of the circulation channel 61 is connected to the exhaust port 11 and the outside. The damper device 60 includes a third damper drive assembly and a third damper 65. The third damper drive assembly drives the third damper 65 to open or close the fourth end 62 of the circulation channel 61.

[0036] As a further embodiment, the first air valve drive assembly 7, the second air valve drive assembly, and the third air valve drive assembly have the same structure. The first air valve drive assembly 7 includes a valve motor 71, a gear 72, and a rack 73. The gear 72 meshes with the rack 73, and the rack 73 is fixedly connected to the first air valve 64. The valve motor 71 drives the gear 72 to rotate, and the gear 72 drives the rack 73 and the first air valve 64 to translate.

[0037] As a further embodiment, the warm air drying mechanism 19 includes an air inlet duct 5, a fan 3, and a heating element 4. The fan 3 is provided with the air inlet 10. One end of the air inlet duct 5 is connected to the air outlet of the fan 3, and the other end of the air inlet duct 5 is provided with the air outlet 14. The heating element 4 is disposed on the air inlet duct 5. Outside air enters the air inlet duct 5 through the air inlet, and is then heated into hot air by the heating element. The hot air then enters the storage cavity from the air outlet.

[0038] As a further solution, the disinfection module 16 is an ultraviolet lamp. Ultraviolet lamps are installed on all walls (including the inside of the door panel) inside the storage cavity 97. In addition, the walls are made of stainless steel liner and have conical surfaces (which serve as reflective surfaces), so as to achieve ultraviolet light irradiation without dead angles and better sterilization effect.

[0039] As a further solution, a photocatalyst 15 is installed inside the storage cavity 97, located at the air outlet 14. The photocatalyst 15 is a substance that uses light energy to catalyze chemical reactions, typically referring to titanium dioxide. Under ultraviolet light, it generates strong oxidizing properties, which can decompose organic matter, thereby sterilizing, deodorizing, and purifying the air; at the same time, it diffuses within the storage cavity 97 with the air blowing from the air outlet, making the effect even more significant.

[0040] The working principle of this high-efficiency and energy-saving maternal and infant sterilization and drying cabinet is as follows:

[0041] When the sterilization function of the baby sterilizer of this utility model is activated, the ultraviolet lamp starts to emit light, and the fan 3 starts to intake air (the fan 3 may also not be activated). At the same time, the first air valve drive assembly 7 drives the first air valve 64 to close the second end 63 of the circulation channel 61, the second air valve drive assembly drives the second air valve 66 to open the third end 68 of the circulation channel 61, and the third air valve drive assembly drives the third air valve 65 to close the fourth end 62 of the circulation channel 61. The second end 63 and the fourth end 62 of the circulation channel 61 are not connected to the outside. The air intake duct 5 and the circulation channel 61 are connected to the exhaust port 11 and the air outlet 14, thereby forming an internal air circulation in the storage cavity. The air in the storage cavity 97 continuously sterilizes the baby products through the air intake duct 5 and the circulation channel 61, resulting in better sterilization.

[0042] After the sterilization and disinfection time is set, the fan 3 continues to intake air. The present invention starts the external air circulation mode. The first air valve drive component 7 drives the first air valve 64 to open the second end 63 of the circulation channel 61, and the second end 63 of the circulation channel 61 is connected to the outside. The second air valve drive component drives the second air valve 66 to open the third end 68 of the circulation channel 61. The third air valve drive component drives the third air valve 65 to open the fourth end 62 of the circulation channel 61, and the fourth end 62 of the circulation channel 61 is also connected to the outside. Therefore, the fan 3 draws fresh air from the outside into the storage cavity 97 from the second end 63 of the circulation channel 61. The air in the storage cavity 97 is discharged from the storage cavity 97 through the exhaust port 11 and the fourth end 62 of the circulation channel 61 in sequence, thereby realizing the fresh air exchange of the disinfection cabinet and solving the odor inside the cabinet.

[0043] When the drying function of the baby sterilizer and drying cabinet of this utility model is activated, the heating element 4 starts to heat up, the fan 3 starts to draw in air, the first air valve drive assembly 7 drives the first air valve 64 to close the second end 63 of the circulation channel 61, the second air valve drive assembly drives the second air valve 66 to open the third end 68 of the circulation channel 61, and the third air valve drive assembly drives the third air valve 65 to close the fourth end 62 of the circulation channel 61. The second end 63 and the fourth end 62 of the circulation channel 61 are not connected to the outside. The air intake duct 5 and the circulation channel 61 are connected to the exhaust port 11 and the air outlet 14, thereby forming an internal air circulation in the storage cavity. The fan 3 blows hot air into the storage cavity 97, and the hot air begins to dry the baby products in the storage cavity 97. The hot air in the storage cavity 97 continuously circulates and dries the baby products through the air intake duct 5 and the circulation channel 61, resulting in faster drying and better sterilization.

[0044] When the drying time is set or after the temperature and / or humidity in the storage cavity reaches the set value, this invention activates the external air circulation mode. The fan 3 maintains air intake, and the first air valve drive assembly 7 drives the first air valve 64 to open the second end 63 of the circulation channel 61, connecting the second end 63 of the circulation channel 61 to the outside. The second air valve drive assembly drives the second air valve 66 to open the third end 68 of the circulation channel 61, and the third air valve drive assembly drives the third air valve 65 to open the fourth end 62 of the circulation channel 61, connecting the fourth end 62 of the circulation channel 61 to the outside. Therefore, the fan 3 draws fresh air from the outside into the storage cavity 97 from the second end 63 of the circulation channel 61, while the humid and hot air in the storage cavity 97 is discharged from the storage cavity 97 through the exhaust port 11 and the fourth end 62 of the circulation channel 61, thereby realizing the replacement of fresh air and the discharge of old air in the disinfection cabinet.

[0045] The working principle of this new type of maternal and infant sterilization and drying cabinet when the drying and sterilization functions are activated simultaneously is the same as the working principle described above, and will not be described in detail here.

[0046] Example 2, see Figure 10As shown, the implementation method of Embodiment 2 is similar to that of Embodiment 1, except that: in this embodiment, the second air valve drive assembly and the second air valve 66 are omitted, and the air valve device 60 is located at the fourth end 62 of the circulation channel 61. The fourth end 62 of the circulation channel 61 connects the exhaust port 11 to the outside, and the third end 68 of the circulation channel 61 connects the exhaust port 11 to the air inlet 10. The air valve device 60 includes a third air valve drive assembly and a third air valve 65. The third air valve 65 is rotatably located between the third end 68 and the fourth end 62 of the circulation channel 61. The third air valve drive assembly drives the third air valve 65 to rotate, and the third air valve drive assembly drives the third air valve 65 to selectively open. When the internal circulation of this invention is started, the third air valve drive assembly drives the third air valve 65 to rotate forward to the set position. The third air valve 65 opens the third end 68 of the circulation channel 61 and closes the fourth end 62 of the circulation channel 61 at the same time. The fourth end 62 of the circulation channel 61 is not connected to the outside. The third end 68 of the circulation channel 61 is connected to the exhaust port 11. Therefore, the circulation channel 61 and the air intake channel are connected to the exhaust port 11 and the air outlet 14. The hot air in the storage cavity 97 is continuously circulated through the air intake channel 5 and the circulation channel 61 to dry the baby products, resulting in faster drying and better disinfection. Conversely, when the external circulation is activated, the third air valve drive assembly drives the third air valve 65 to rotate in the opposite direction to the set position. The third air valve 65 closes the third end 68 of the circulation channel 61 and opens the fourth end 62 of the circulation channel 61. The third end 68 of the circulation channel 61 is not connected to the exhaust port 11, while the fourth end 62 of the circulation channel 61 is connected to the outside. Therefore, the exhaust port 11 and the air outlet 14 are not connected. The hot air in the storage cavity 97 is discharged from the storage cavity 97 through the exhaust port 11 and the fourth end 62 of the circulation channel 61 in sequence. Meanwhile, the fan 3 draws fresh air from the outside into the storage cavity 97 from the second end 63 of the circulation channel 61, thereby realizing the fresh air exchange of the disinfection cabinet and solving the odor problem inside the cabinet.

[0047] Example 3, see Figure 11 and Figure 12 As shown, the implementation method of Embodiment 3 is similar to that of Embodiment 1, except that the disinfection module 16 also includes a steam generator. The steam generator is located at the bottom of the storage cavity 97. When the high-temperature steam generated by the steam generator rises, it directly disinfects the baby products at high temperature.
