[0035] The inner cavity 2 is provided with a first exhaust hole 9 on the rear side. The inner cavity 2 (drying area 7) is connected to the air inlet of the hot air assembly 3 through the first exhaust hole 9 to form an internal circulation air supply. The height of the first exhaust hole 9 is higher than the height of the air outlet 5. Since the hot air entering the inner cavity 2 from the air outlet 5 will rise, setting the first exhaust hole 9 at a higher position is beneficial for the hot air in the inner cavity 2 to return to the hot air assembly 3.

[0036] The inner cavity 2 is provided with several partitions 6, which divide the inner cavity 2 into several drying areas 7 arranged vertically. The air outlet assembly is respectively arranged on each drying area 7 to form vertical airflow on the inner cavity 2. The drying device, air outlet assembly, drying area 7 and first exhaust hole 9 correspond one-to-one. The drying device is distributed vertically in the electrical chamber 10.

[0037] In this embodiment, a partition 6 is provided, which divides the inner cavity 2 into two drying areas 7 arranged vertically. Two air outlet assemblies are provided and are respectively arranged on each drying area 7. Two drying devices are provided and are distributed vertically in the electrical chamber 10.

[0038] Sterilization devices 12 are respectively provided on the peripheral walls of the inner cavity 2 (i.e., the left and right side walls, top wall, bottom wall and rear wall of the inner cavity 2) and the upper and lower sides of the partition 6. The sterilization devices 12 are located on the left and right sides, upper and lower sides and rear side of the drying area 7, so that all positions of the drying area 7 can be irradiated by ultraviolet light, thereby sterilizing the items on the inner cavity 2 in all directions.

[0039] The rear end of the partition 6 is provided with a first coupler 26 and a first magnetic attraction component 18. The rear wall of the inner cavity 2 is provided with a second coupler 27 and a second magnetic attraction component 19. The first coupler 26 is electrically connected to the sterilization device 12 on the partition 6. The partition 6 is slidably mounted on the inner cavity 2. When the partition 6 is pushed into the inner cavity 2, the first coupler 26 and the second coupler 27 are coupled to each other and form a conductive contact to achieve electrical connection, thereby powering the ultraviolet lamp plate 24 on the partition 6. The first magnetic attraction component 18 and the second magnetic attraction component 19 attract each other to fix the partition 6 on the inner cavity 2. The first magnetic attraction component 18 and the second magnetic attraction component 19 are magnets. A power board 29 is provided in the electrical compartment 10, and the second coupler 27 is electrically connected to the power board 29.

[0040] The sterilization device 12 on the partition 6 includes an ultraviolet lamp plate 24, ultraviolet lamp beads 30, and a lamp cover 36. The partition 6 includes a mounting plate 25 and pressure plates 37 installed on the upper and lower sides of the mounting plate 25 respectively. The ultraviolet lamp plate 24 is snapped onto the mounting plate 25, the ultraviolet lamp beads 30 are arranged on the ultraviolet lamp plate 24, and the lamp cover 36 covers the ultraviolet lamp beads 30 and is pressed between the mounting plate 25 and the pressure plate 37. The first coupler 26 and the first magnetic suction component 18 are located at the rear end of the mounting plate 25. The first coupler 26 is electrically connected to the ultraviolet lamp plate 24. The ultraviolet lamp plate 24 is powered by a low-voltage 5V power supply, which is safe and stable and does not affect the cleaning of the partition 6. The partition 6 is electrically connected through the coupler. The coupler has good contact and there will be no problem of poor contact after the partition 6 is disassembled and reassembled many times. This drying cabinet is mainly used to dry the moisture of the items, so the pollution generated is small. In addition, the sterilization device 12 sterilizes the drying area 7, so the partition 6 does not need to be removed for cleaning frequently.

[0041] The sterilization device 12 on the inner cavity 2 includes an ultraviolet lamp plate 24, ultraviolet lamp beads 30, and a lamp cover 36. A first fixing plate 38 is provided on the periphery of the inner cavity 2, and a second fixing plate 39 is provided on the periphery of the cabinet 1. A lamp holder 40 is provided between the first fixing plate 38 and the second fixing plate 39. The lamp holder 40 is fixed to the top of the inner cavity 2 by screws. A positioning post 8 is provided on the lamp holder 40. The ultraviolet lamp plate 24 is snapped on the lamp holder 40, the ultraviolet lamp beads 30 are arranged on the ultraviolet lamp plate 24, and the lamp cover 36 covers the ultraviolet lamp beads 30. The positioning post 8 abuts against the second fixing plate 39, and the lamp cover 36 is pressed between the ultraviolet lamp plate 24 and the first fixing plate 38, so that the sterilization device 12 is pressed between the lamp holder 40 and the first fixing plate 38.

[0042] A sliding seat 31 is provided on the inner cavity 2, and the partition 6 is slidably supported on the sliding seat 31, thereby realizing the installation and removal of the partition 6.

[0043] The drying area 7 is provided with a mounting base 33 for mounting shelves 32. The shelves 32 are supported and mounted on the mounting base 33. The shelves 32 are used to place items that need to be dried, such as baby bottles, nipples, bottle caps or other items. This drying cabinet is mainly used for drying baby bottles.

[0044] An air inlet 13 is provided on the rear side of the cabinet 1, connecting to the outside. The electrical compartment 10 is connected to the air inlet 13. A filter element 14, which is filter cotton, is provided on the air inlet 13 to filter the air. A sterilization component 28 is provided in the electrical compartment 10 corresponding to the position of the air inlet 13. The sterilization component 28 includes a lamp panel 21 and ultraviolet lamp beads 22, which are used to sterilize the filtered air to ensure that the hot air entering the inner cavity 2 is clean and hygienic. The electrical compartment 10 is connected to the hot air component 3. The air inlet of the hot air component 3 can introduce a small amount of cold air from the outside to replenish the inner cavity 2 with fresh air and ensure that the air in the inner cavity 2 is fresh. On the other hand, the fan 15 and the hot air duct 16 are not sealed. In this design, air from the electrical chamber 10 enters the fan 15, and the air from the electrical chamber 10 also enters the hot air channel 16 through the gap between the fan 15 and the hot air channel 16. If the fan 15 and the hot air channel 16 were sealed, it would be very costly. Therefore, this design does not use a sealing structure, but instead uses a filter component 14 and a sterilization component 28 to allow air from the electrical chamber 10 to enter the fan 15 and the hot air channel 16. It is only necessary to ensure that the air in the electrical chamber 10 is clean. In addition, according to the characteristic of hot air rising, the hot air in the inner cavity 2 will flow upward when passing through the fan 15 and the hot air channel 16, and will not leak into the electrical chamber 10 through the gap between the fan 15 and the hot air channel 16.

[0045] A second exhaust vent 11 is provided on the rear side of the inner cavity 2, and an exhaust vent 41 connecting to the outside is provided on the rear side of the cabinet 1. The inner cavity 2 is connected to the exhaust vent 41 through the second exhaust vent 11. A small part of the air in the inner cavity 2 will be discharged to the outside through the second exhaust vent 11 and the exhaust vent 41. The purpose is to discharge the moisture in the inner cavity 2 to the outside and improve the drying effect, because drying items will generate moisture. At the same time, it maintains the air pressure balance in the inner cavity 2.

[0046] An exhaust duct 23 is provided in the electrical room 10, and the second exhaust hole 11 is connected to the exhaust hole 41 through the exhaust duct 23.

[0047] The hot air assembly 3 includes a fan 15, a hot air duct 16, and a heating element 17. The air inlet of the fan 15 is connected to the inner cavity 2 and the electrical chamber 10, respectively. The air outlet of the fan 15 is connected to the hot air duct 16, and the hot air duct 16 is connected to the air inlet duct 4. The heating element 17 is installed in the hot air duct 16 and is a PTC heater. When the fan 15 is working, the air in the inner cavity 2 (drying area 7) enters the hot air duct 16. The heating element 17 heats the air, and then the hot air reaches the air outlet 5 through the air inlet duct 4 and then enters the drying area 7 to dry the items on the shelf 32. Under the action of the fan 15, the hot air in the drying area 7 will re-enter the hot air duct 16 to form an internal circulation air supply. At the same time, a small amount of cold air from the outside will enter the fan 15 and the hot air duct 16, and after being heated by the heating element 17, it will enter the inner cavity 2. A small part of the air in the inner cavity 2 will be discharged to the outside through the second exhaust hole 11 and the exhaust vent 41.

[0048] The air inlet channel 4 includes a first channel 34 located on the rear side of the inner cavity 2 and a second channel 35 located on the left and right sides of the inner cavity 2. The hot air channel 16, the first channel 34 and the second channel 35 are connected in sequence. The first channel 34 is connected to the air outlet 5 on the rear side of the inner cavity 2, and the second channel 35 is connected to the air outlet 5 on the left and right sides of the inner cavity 2.

[0049] The bottom of the inner cavity 2 is provided with a water collection tank 20. The inner cavity 2 is connected to the water collection tank 20. When the items are dried, hot and humid air, i.e. water vapor, will be generated. Part of the hot and humid air is discharged to the outside through the second exhaust hole 11, while part of the hot and humid air will condense into condensate when it hits the side wall of the inner cavity 2 due to the cold. The condensate flows down the side wall of the inner cavity 2 to the water collection tank 20. The condensate on the water collection tank 20 will also be dried by the hot air generated by the hot air component 3, and will turn back into water vapor. Finally, it will also be discharged to the outside through the second exhaust hole 11.
