For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0026] As Figures 1 to 5As shown, the embodiment of the present application provides a kind of ultraviolet disinfection cabinet, including outer shell 1 and setting in outer shell 1 inner box 2.Outer shell 1 to inner box 2 play the role of protection, inner box 2 is used to place the article in it is dried, disinfection, ultraviolet emission device is arranged in inner box 2, for the article placed in inner box 2 is disinfected.Outer shell 1 and inner box 2 are usually cubic.Outer shell 1 can be made of plastic, and inner box 2 is made of metal.

[0027] As Figure 4 Shown, inner box 2 surrounds and holds cavity 21, for placing the article to be disinfected and dried.The front end of inner box 2 is provided with open end, to take and place article in holding cavity 21 by open end.Inner box 2 is provided with air inlet 22 and exhaust port 23 on the side wall, air can be blown into inner box 2 through air inlet 22, and gas in inner box 2 is discharged through exhaust port 23.

[0028] In the holding cavity 21 of inner box 2, infrared temperature sensor and humidity sensor (not shown in the figure) are arranged.In which, infrared temperature sensor can be set on the set position as required, for example, set on the inner side wall of inner box 2, for collecting the surface temperature data of the article placed in inner box 2;Humidity sensor is arranged at exhaust port 23, for humidity data in inner box 2.

[0029] Drying assembly is arranged in outer shell 1, which is communicated with air inlet 22 arranged on inner box 2, for heating external air and sending into inner box 2 through air inlet 22.

[0030] Further, air inlet 22 is arranged at the lower part of the side wall of inner box 2 opposite to its open end.Drying assembly includes fan and heating device (not shown in the figure), the outlet of fan is communicated with air inlet 22 arranged on the side wall of inner box 2, and heating device is used to heat the air blown by the outlet of fan, to deliver heated air to inner box 2, to heat and dry the article placed in holding cavity 21 of inner box 2.Air inlet 22 is arranged at the lower part of the side wall of inner box 2, so that heated air moves from the bottom of holding cavity 21 to the upper part of holding cavity 21 under the drive of fan, so as to heat and dry the article placed in holding cavity 21 from bottom to top as much as possible.

[0031] Further, as Figure 4As shown, the exhaust port 23 is arranged at the upper portion of the side wall of the inner box body 2 opposite to the open end, that is, the exhaust port 23 and the air inlet 22 are arranged on the same side wall of the inner box body 2, and the exhaust port 23 is arranged above the air inlet 22. After the drying assembly inputs the heated air from the air inlet 22 arranged at the lower portion of the side wall of the inner box body 2 into the containing cavity 21, the hot air moves from the bottom of the containing cavity 21 to the bottom, heats and dries the articles placed in the containing cavity 21 in the process of moving, and is discharged from the inner box body 2 through the exhaust port 23 arranged at the upper portion of the side wall of the inner box body 2. The humidity sensor arranged at the exhaust port 23 collects the humidity data of the gas discharged from the exhaust port 23 at a set frequency.

[0032] Correspondingly, as shown in the figure, the outer box body 1 is provided with an opening corresponding to the air inlet 22 and the exhaust port 23 on the side wall of the inner box body 2, so that the ambient air can enter the inner box body 2 through the air inlet 22 of the outer box body 1. And the gas in the inner box body 2 can be discharged to the environment through the outer box body 1 after being discharged from the exhaust port 23 of the inner box body 2. Figure 3

[0033] The ultraviolet disinfection cabinet in the embodiment of the present application further comprises a control module, which can acquire the temperature data of the articles placed in the inner box body 2 collected by the infrared temperature sensor and the humidity data of the gas discharged from the exhaust port 23 collected by the humidity sensor, and the control module can control the operation of the drying assembly according to the above two data.

[0034] Specifically, after the articles to be dried are placed in the containing cavity 21 of the inner box body 2, the infrared temperature sensor arranged in the containing cavity 21 collects the temperature of the surface of the articles at a set frequency (for example, collecting temperature data every five seconds), and sends the collected temperature data to the control module. The humidity sensor arranged at the exhaust port 23 collects the humidity data of the gas discharged from the exhaust port 23 at a set frequency.

[0035] When the user inputs the instruction of drying the articles through the control module, the control module starts the fan and the heating device in the drying assembly, and transports the hot air from the bottom of the inner box body 2 to the containing cavity 21 through the air inlet 22, to dry the articles placed in the containing cavity 21.

[0036] ​While the fan continuously delivers hot air into the receiving cavity 21, an infrared temperature sensor periodically collects temperature data of the item's surface, and a humidity sensor collects humidity data of the gas discharged from the exhaust port 23. Simultaneously, the control module continuously acquires both the temperature data of the item's surface and the humidity data of the gas discharged from the exhaust port 23, and determines whether the items placed in the receiving cavity 21 have achieved the set drying effect based on these two data points. For example, depending on the type of item placed in the receiving cavity 21, the two data points are compared with the data stored in the control module to determine the drying effect on the items.

[0037] Furthermore, such as Figure 3 As shown, to more accurately evaluate the drying effect on items placed in the inner chamber 2, a weighing module 3 is installed at the bottom of the outer shell 1 to collect the weight of the items placed in the inner chamber 2. The control module is connected to the weighing module 3 to acquire the weight data of the items in the inner chamber 2 collected by the weighing module 3. Based on the weight change of the items placed in the inner chamber 2, and combined with the temperature data of the items placed in the inner chamber 2 collected by the infrared temperature sensor and the humidity data of the gas discharged from the exhaust port 23 collected by the humidity sensor (the longer the drying time, the lower the humidity of the gas discharged from the exhaust port 23), the drying effect on the items placed in the inner chamber 2 is comprehensively evaluated. Furthermore, the duration of ultraviolet disinfection and the drying temperature can be set according to the weight of the items placed in the inner chamber 2.

[0038] Specifically, after the items to be dried are placed into the receiving cavity 21 of the inner chamber 2, the weighing module 3 located at the bottom of the outer chamber 1 collects the weight data of the items placed in the receiving cavity 21 at a set frequency (for example, temperature data is collected every five seconds), and sends the collected weight data to the control module. During the drying process, the control module calculates the change in the weight of the items based on the acquired weight data of the items placed in the receiving cavity 21. This data can be used to determine the drying effect of the items. At the same time, the control module can combine the aforementioned weight change of the items with the humidity change of the gas discharged from the exhaust port 23 and the temperature data of the object surface to determine whether the items placed in the receiving cavity 21 have reached the set drying standard. If the set drying standard has been reached, the control module controls the fan and / or heating device in the drying assembly to stop operating.

[0039] The items placed in the receiving cavity 21 of the inner box 2 for drying can be of various types, such as infant clothing, toys, baby bottles, water cups, or adult water cups. Figure 4As shown, in order to simultaneously dry and sterilize different types of items, the inner chamber 2 has support portions 24 on two opposite side walls adjacent to its opening end. These support portions 24 are used to place partitions, dividing the accommodating cavity 21 into a multi-layered structure, allowing different types of items to be placed on partitions of different heights. In one specific embodiment, three shelves are placed on the support portions 24: the top shelf holds clothing (hanging), the middle shelf holds baby bottles, and the bottom shelf holds toys.

[0040] Furthermore, the support 24 can be detachably mounted on the side wall of the inner box 2, and its height on the side wall can be adjusted. For example, a hook-and-loop structure can be provided on the side wall of the inner box 2, allowing the support 24 to be hooked or clipped onto the side wall of the inner box 2. This allows for flexible adjustment of the height of each compartment as needed, making it suitable for storing items of various types and sizes.

[0041] In addition, such as Figure 1 and Figure 5 As shown, the outer casing 1 has an openable door 11 at the opening end of the inner casing 2, which is used to close the opening end of the inner casing 2. The door 11 can be hinged to the side wall of the outer casing 1.

[0042] like Figure 4 and Figure 5 As shown, reflective inner liner 4 is provided on the surface of the door 11 opposite to the receiving cavity 21 and on the inner wall of the inner box 2 to reflect the ultraviolet rays emitted by the ultraviolet emitting device. The reflective inner liner 4 can be made of uniformly arranged ultra-mirror-finished stainless steel with convex arc surfaces to increase the angle of ultraviolet irradiation and improve the irradiation effect of ultraviolet rays on the items placed in the receiving cavity 21.

[0043] Furthermore, to facilitate observation of the interior of the inner box 2, an observation window (not shown in the figure) can be provided on the door 11. Correspondingly, a sensor light (not shown in the figure) can also be installed inside the inner box 2. This sensor light is electrically connected to the control module and can illuminate the interior of the inner box 2 so that the user can observe the situation inside the inner box 2 through the observation window.

[0044] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
