[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-4 In an embodiment of the utility model, an air duct assembly with a sterilization and disinfection function includes an air housing 1 and a connected fan 2, a main air duct 3 is formed in the air housing 1, and the air housing 1 has an air outlet 4 corresponding to the main air duct 3, so as to form a fluid channel that enters along the air inlet of the fan 2 and flows out from the air outlet 4 of the main air duct 3;

[0032] The air housing 1 is connected to a sterilization module, and the ion emitting end 5 of the sterilization module at least partially extends into the main air duct 3 to sterilize the fluid in the main air duct 3 . A heating component 6 is also provided in the main air duct 3 .

[0033] The utility model also proposes a disinfection device, including a disinfection device main body, the disinfection device main body having a disinfection chamber for accommodating the product to be disinfected, and an air duct component acting on the disinfection chamber is arranged in the disinfection device main body, wherein the air duct component is the above-mentioned air duct component with sterilization and disinfection function.

[0034] In the technical solution of the utility model, a sterilization and disinfection module is connected to the shell of the air duct component, and the sterilization and disinfection module can be any one of a negative ion generator, a positive and negative ion generator, a water ion generator, etc., and the ion emitting end 5 of the sterilization and disinfection module is extended into the main air duct 3 to achieve sterilization and disinfection of the fluid in the main air duct 3, so that the wind blown out by the air duct component can be purified. Therefore, when the air duct component is used in corresponding disinfection equipment such as a disinfection cabinet, a disinfection box, a liquid heater (steam disinfection) and other equipment, it can effectively ensure that the wind blown into the disinfection chamber of the product to be disinfected in the disinfection equipment through the air duct component can be relatively clean, thereby effectively avoiding the problem of secondary infection of the items that need to be sterilized.

[0035] Among them, the sterilization and disinfection module takes the positive and negative ion generator as an example. Through the setting of the positive and negative ion generator, the ions and negative ions generated at the same time generate huge energy release at the moment of neutralization of positive and negative charges in the air, which in turn causes changes in the structure of surrounding bacteria or energy conversion, and then causes the death of bacteria to achieve its sterilization effect. Since the number of negative ions is greater than the number of positive ions, the excess negative ions still float in the air, which can achieve the health care effects of eliminating smoke, dust, and odor, improving the quality of air to promote human health; so that the wind blown out by this air duct component can be purified, achieving the effect of sterilization and disinfection.

[0036] More specifically, in the embodiment of the utility model, one end of the main air duct 3 corresponding to the fan 2 and one end of the main air duct 3 corresponding to the air outlet 4 are arranged in an arc transition, and the ion emitting end 5 of the sterilization and disinfection module is arranged close to the air outlet 4.

[0037] By placing the ion emitting end 5 of the sterilization and disinfection module close to the air outlet 4, especially the orientation of the ion emitting end 5 can be consistent with the air outlet direction of the main air duct 3, the negative ions generated by the ion emitting end 5 can be stably, efficiently and continuously uniformly generated, that is, the concentration of the generated negative ions can be effectively guaranteed, thereby effectively ensuring that the wind blown out of the air duct component can be purified; and through the setting of the end of the main air duct 3 corresponding to the fan 2 and the end of the main air duct 3 to the air outlet 4 with an arc surface transition, not only can it guide the wind blown out of the air duct component, but the design of the arc surface transition can make the wind blown out of the air duct component softer, achieving the effect of reducing noise, and at the same time, combined with the setting of placing the ion emitting end 5 of the sterilization and disinfection module close to the air outlet 4, the ion emitting end 5 can minimize the impact on the air intake of the end of the main air duct 3 corresponding to the fan 2 as much as possible, and can ensure that the wind blown out of the air duct component can pass through the ion emitting end 5, thereby effectively enhancing the wind blown out of the air duct component to achieve the purpose of sterilization and disinfection.

[0038] More specifically, in the embodiment of the utility model, the outer surface of the wind housing 1 has an assembly position 7 corresponding to the ion emitting end 5 of the sterilization and disinfection module, so as to fix the ion emitting end 5 of the sterilization and disinfection module to the wind housing 1 .

[0039] It is understandable that the sterilization and disinfection module generally includes a sterilization and disinfection module body and its corresponding ion emission end 5. By extending the ion emission end 5 of the sterilization and disinfection module at least partially into the main air duct 3, rather than placing the sterilization module as a whole into the main air duct 3, the space occupied by the sterilization module in the main air duct 3 can be reduced, that is, the impact on the air volume can be effectively reduced; through the design of the assembly position 7 on the outer surface of the wind shell 1, the ion emission end 5 can be fixedly connected to the wind shell 1;

[0040] Specifically, the assembly position 7 includes a first connecting column 8 and a second connecting column 9 protruding from the outer surface of the wind shell 1, so as to be fixedly connected to the ion emitting end 5 of the sterilization and disinfection module through the first connecting column 8, and a through hole 10 is arranged along the axial direction of the second connecting column 9, which penetrates itself and extends to the main air duct 3, so that the ion emitting end 5 of the sterilization and disinfection module can be extended into the main air duct 3 through the through hole 10.

[0041] More specifically, in the embodiment of the utility model, the ion emitting end 5 of the sterilization and disinfection module includes an electrode portion 11 and a bracket portion 12 connected to the electrode portion 11, the bracket portion 12 is provided with a connecting hole 17, and the first connecting column 8 is provided with a threaded hole 13 corresponding to the connecting hole 17;

[0042] The tip of the electrode portion 11 extends into the main air duct 3 through the through hole 10 .

[0043] The electrode part 11 can be understood as a discharge tip, that is, the ion emission end 5 of the sterilization and disinfection module can be fixedly connected by conventional screw fastening of the first connecting column 8 and the bracket part 12, which is convenient for assembly.

[0044] More specifically, in the embodiment of the present invention, a sealing member 14 is provided between the connection between the ion emitting end 5 of the sterilization and disinfection module and the wind housing 1 .

[0045] By providing the sealing member 14 , the ion emitting end 5 and the wind housing 1 can be closely contacted, thereby facilitating ensuring the air output of the air duct assembly.

[0046] More specifically, in the embodiment of the utility model, the heating component 6 includes a PTC heating element, a fixing element 15 and a heating sealing cover plate 16. One end of the wind housing 1 is connected to the fan 2, and the other end forms the air outlet 4. The PTC heating element is arranged inside the main air duct 3 through the fixing element 15. The heating sealing cover plate 16 is arranged below the fixing element 15 and is clamped with the wind housing 1.

[0047] That is, the wind blown out by the fan 2 is heated by the PTC heating element and then transmitted through the main air duct 3. During this period, it is also purified by the sterilization and disinfection module, so that the air duct assembly can have the function of sterilization and drying.

[0048] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
