[0039] The embodiments of the present application provide a sterilization and drying device, Figure 1 is a schematic view of a sterilization and drying device provided by the embodiments of the present application, Figure 2 is Figure 1 the air outlet cavity and the air duct of the sterilization and drying device in the middle, referring to Figure 1 and Figure 2 The sterilization and drying device comprises:

[0040] The device main body 10 and the cover body 20, one side of the cover body 20 is connected with the device main body 10; the device main body 10 is provided with a containing cavity 11, the containing cavity 11 is used for containing the dried object; at least one side wall of the containing cavity 11 is provided with an air outlet cavity 31 and a plurality of air ducts 32 surrounding the air outlet cavity 31, the air outlet cavity 31 is provided with a hot air generating device 40, the plurality of air ducts 32 are communicated with the outlet of the air outlet cavity 31; the surface of the side wall provided with the air outlet cavity 31 is provided with a plurality of air outlets 61, the air duct 32 is communicated with the containing cavity 11 through the air outlet 61;

[0041] The hot air output by the hot air generating device 40 is output into the receiving cavity 11 through multiple air ducts 32 and multiple air outlets 61; multiple germicidal lamps 80 are provided on the surface of the cover 20 adjacent to the receiving cavity 11.

[0042] The germicidal lamp 80 can be an ultraviolet lamp. The air outlet 31, air duct 32, and air outlet 61 can be provided on only one side wall of the receiving cavity 11, or they can be provided on two or more side walls of the receiving cavity 11. Multiple air ducts 32 are arranged around the air outlet 31; they can surround a portion of the air outlet 31 or the entire area of ​​the air outlet 31. The number of air ducts 32 can be 3, 4, 5, 6, etc. The width and length of each air duct 32 can be the same or different. Each air duct 32 can be connected to multiple air outlets 61. Each air outlet 61 can be connected to only one air duct 32, or it can be connected to two or more air ducts 32.

[0043] For example, refer to Figure 1 and 2 Around the air outlet cavity 31, 2n air ducts can be arranged. On each of the opposite sides of the air outlet cavity 31, n air ducts 32 are arranged, where n is an integer greater than or equal to 1, for example, n is 2, 3, 4, etc. At the air outlet 61 of the air outlet cavity 31, the n air ducts located on the same side of the air outlet cavity 31 are arranged sequentially in the direction away from the air outlet cavity 31, and the length of the air ducts 32 decreases sequentially in the direction away from the air outlet cavity 31, that is, the length of the air duct 32 adjacent to the air outlet cavity 31 is the longest, and the length of the air duct 32 furthest from the air outlet cavity 31 is the shortest. Each air duct 32 includes an air inlet (the beginning of the air duct) and an air duct end.

[0044] Specifically, the inlets of multiple air ducts 32 are arranged sequentially at the outlet of the air outlet cavity 31. After the hot air generating device 40 in the air outlet cavity 31 outputs hot air, the hot air enters each air duct 32 and then enters the receiving cavity 11 through multiple air outlets 61. By introducing hot air into multiple air ducts 32, the hot air is divided into a planar shape and exited through multiple air outlets 61 connected to the air ducts 32, achieving multi-point air outlet and improving the air outlet area and uniformity of the hot air.

[0045] This utility model embodiment adopts a multi-channel air outlet structure, which divides the hot air generated by a single heat source into multi-point hot air in a planar shape, thereby avoiding damage to the dried object caused by the high temperature of a single-point air outlet; at the same time, with the increase of the air outlet area, the area of ​​the dried object receiving hot air at the same time also increases, and the amount of moisture evaporated also increases, and it avoids uneven heating of the dried object, which may lead to over-drying or slow drying, thereby improving the drying rate.

[0046] Based on the above embodiments, optionally, the side wall with the air outlet cavity 31 includes a bottom plate 50 and a top plate 60, with the top plate 60 disposed on the side of the bottom plate 50 adjacent to the receiving cavity 11; the air outlet 61 is disposed on the top plate 60 and penetrates the top plate 60.

[0047] A partition plate 70 is provided between the bottom plate 50 and the top plate 60. The partition plate 70 divides the space between the bottom plate 50 and the top plate 60 into an air outlet 31 and multiple air ducts 32.

[0048] The top plate 60 is the side wall surface of the cavity 11.

[0049] Figure 3 This is a schematic diagram of another air outlet cavity and air duct provided by an embodiment of the present utility model. Optionally, based on the above embodiments, refer to...

[0050] Specifically, the airflow regulating mechanism 30 can adjust the airflow entering each air duct 32 by adjusting the size of the inlet of each air duct 32. By setting the airflow regulating mechanism 30, the airflow entering each air duct 32 can be adjusted according to the drying requirements. For example, when there is only a certain area in the receiving cavity 11 with the item to be dried, the inlets of some air ducts 32 can be closed, and only the outlets of the air ducts 32 corresponding to the item to be dried can be allowed to emit air, thereby reducing energy consumption.

[0051] Based on the above embodiments, optionally, the air volume adjustment mechanism 30 includes a plurality of baffles 301 and a drive mechanism 302. Each baffle 301 corresponds to a duct 32. Each baffle 301 is disposed at the inlet of its corresponding duct 32. The drive mechanism 302 is used to adjust the angle between the baffle 301 and the side wall of the duct 32 to adjust the size of the inlet of the duct 32.

[0052] Specifically, the fixed end of the baffle 301 can be connected with the side wall of the air duct 32, i.e., connected with the partition plate 70, the top plate 60 or the bottom plate 50, and the driving mechanism 30 is used to drive the baffle 301 to rotate around the connection end of the baffle 301 and the side wall of the air duct 32, so as to adjust the included angle between the baffle 301 and the side wall of the air duct 32. By adjusting the size of the air duct 32 inlet by using the baffle 301 and the driving mechanism 302, the structure is simple, and the manufacturing difficulty and cost can be reduced.

[0053] It should be noted that the specific type of the driving mechanism 302 is not limited in the embodiment, as long as it can drive the baffle 301 to rotate. For example, the driving mechanism 302 can include a transmission mechanism and a motor.

Optionally, the number of the hanging rods 90 is at least two; and the at least two hanging rods 90 are arranged in sequence.

[0060] Specifically, by arranging two or more than two hanging rods 90 in sequence, the hung dried objects can be kept at a reasonable interval, the contact area between the dried objects and the hot air is increased, and the drying rate is further improved.

[0061] It should be noted that the spacing between the suspension rods 90 can be equal or unequal. The sidewall of the receiving cavity 11 can be provided with positioning grooves (not shown in the figure), and both ends of the suspension rods 90 are fixed in the positioning grooves. The number of positioning grooves can be more than twice the number of suspension rods 90, allowing the user to adjust the position of the suspension rods 90 as needed, thereby adjusting the spacing between the suspension rods 90 to meet the drying requirements of different items.
