Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

The following describes a sterilizer 100 according to an embodiment of the present invention with reference to the drawings, and the sterilizer 100 may be used to sterilize air.

As shown in fig. 1 and 2, a sterilizer 100 according to an embodiment of the present invention includes a housing 1, a blower part 3, a first sterilization module 2, and a second sterilization module 4.

As shown in fig. 1, the housing 1 defines a containing cavity, and the housing 1 is provided with an air inlet 111 and an air outlet respectively communicated with the containing cavity, so that air can enter the housing 1 through the air inlet 111 and finally flow out of the housing 1 through the air outlet.

As shown in fig. 1 and fig. 2, the fan component 3 is disposed in the accommodating cavity, the first disinfection module 2 and the second disinfection module 4 are respectively located in the accommodating cavity, the first disinfection module 2 is disposed on an upstream side of the fan component 3 along an air outlet direction, the second disinfection module 4 is located on a downstream side of the fan component 3 along the air outlet direction, where "upstream" and "downstream" both refer to a flow direction of an air flow, the air flow passes through the upstream side first and then passes through the downstream side, that is, the first disinfection module 2 is disposed between the fan component 3 and the air inlet 111, and the second disinfection module 4 is disposed between the fan component 3 and the air outlet, so that, in a process that the fan component 3 operates to drive the air flow to enter the accommodating cavity from the air inlet 111 and flow in the accommodating cavity, the air flow can firstly flow through the first disinfection module 2 on the upstream side of the fan component 3 for disinfection, the air current after being disinfected flows to fan part 3 again, and the second disinfection and sterilization module 4 that later can flow through fan part 3 downstream side carries out disinfection and sterilization once more, flows out from the air outlet again at last to make sterilizing machine 100 have dual disinfection and sterilization's effect, reach efficient disinfection and sterilization effect.

In addition, the reason why the first disinfection module 2 and the second disinfection module 4 are respectively arranged on the upstream side and the downstream side of the fan component 3 is chosen instead of arranging a plurality of disinfection modules on the upstream side or the downstream side of the fan component 3 is that if a plurality of disinfection modules are arranged on the upstream side of the fan component 3, the airflow is firstly subjected to disinfection treatment by the plurality of disinfection modules and then is extracted by the fan component 3, so that the resistance of the fan component 3 for extracting the air is increased, the energy consumption of the fan component 3 during operation is increased, the air output of the fan component 3 is reduced, and if a plurality of disinfection modules are arranged on the downstream side of the fan component 3, the airflow sent by the fan component 3 is firstly subjected to disinfection treatment by the plurality of disinfection modules and then flows to the air outlet, so that the speed of the airflow finally flowing out from the air outlet is reduced, and thus the airflow cannot be rapidly diffused into the indoor space, making it difficult to apply the sterilizer 100 to the sterilization treatment of the large indoor space. In view of this, here, set up first disinfection and sterilization module 2 and second disinfection and sterilization module 4 respectively at the upstream side and the downstream side of fan part 3, on the one hand make sterilizer 100 itself have dual disinfection and sterilization's effect, reach efficient disinfection and sterilization effect, on the other hand can compromise the power consumption of fan part 3 and the application space scope of sterilizer 100, make the resistance that fan part 3 extracted the air be unlikely to too big in order to influence the power consumption and the amount of wind of fan part 3, can also make the air current after the disinfection and sterilization process when flowing out from the air outlet, can have great speed, and then can spread to the interior space rapidly, make sterilizer 100 can use in the disinfection and sterilization process of great interior space.
