The following detailed description is to be read in connection with the drawings and the detailed description.
Fig. 1 is a schematic view of a portable sterilization device provided in an embodiment of the present application, fig. 2 is another schematic view of the portable sterilization device provided in the embodiment of fig. 1, and fig. 3 is another schematic view of the portable sterilization device provided in the embodiment of fig. 1. Referring to fig. 1, 2 and 3, the portable sterilizer includes a lamp housing 10, a main body housing 20, a handle 30 and a base 40, wherein the handle 30 is located between the main body housing 20 and the base 40;
a hollow cavity is formed on the outer wall of the main body shell 20, a light source plate 102, a radiator 103, a fan 104, a control plate 105 and at least one UV-LED lamp bead 101 are arranged in the cavity, and an indicator lamp 106 and a sterilization switch 107 are arranged on the outer wall of the main body shell 20;
the main body housing 20 includes a light outlet 108, the light source board 102 has a rectangular structure with a chamfer, the light source board 102 includes a first surface S1 and a second surface S2 which are oppositely disposed, the light source board 102 is located at the light outlet 108 of the main body housing 20, and the first surface S1 is located at a side of the second surface S2 facing the light outlet 108;
the UV-LED lamp beads 101 are positioned on one side of the light source board 102 facing the light outlet 108, the UV-LED lamp beads 101 comprise lamp beads and electric connecting parts electrically connected with the lamp beads, the electric connecting parts are electrically connected with the first surface S1 of the light source board 102, the light emitting surfaces of the lamp beads are positioned on one side of the electric connecting parts far away from the first surface S1, and at least part of the light emitting surfaces of the lamp beads face the light outlet 108;
the lampshade 10 is of a hollow annular structure, the lampshade 10 comprises a first annular bottom surface D1 and a second annular bottom surface D2 which are oppositely arranged, and a side wall D3 which is positioned between the first annular bottom surface D1 and the second annular bottom surface D2, the first annular bottom surface D1 of the lampshade 10 is fixed on the first surface S1 of the light source plate 102 and is attached to the first surface of the light source plate 102, and the side wall of the lampshade 10 is arranged around the UV-LED lamp bead 101;
the heat sink 103 is a rectangular structure located on one side of the light source board 102 far away from the light outlet 108, and a fan 104 is further disposed on one side of the heat sink far away from the light source board 102; the fan 104 includes fan blades and a fan shroud; wherein, the light source plate 102, the radiator 103, the fan 104 and the control plate 105 are coaxially arranged with the cavity;
the control board 105 is a rectangular printed circuit board including at least one circuit part, and is electrically connected to the light source board 102 through a first wire L1, and is electrically connected to the fan 104 through a second wire L2; the battery pack 401 is provided in the base 40, and the control board 105 is electrically connected to the battery pack 401 through a third wire L3.
In this embodiment, the number and power of the UV-LED lamp beads 101 can be flexibly set according to the specific application scenario of the sterilization apparatus. For example, for a general household sterilization device, 9 UV-LED lamp beads may be disposed on the light source plate, and for a medical grade sterilization device, the number of UV-LED lamp beads may be increased to 25. Obviously, the larger the power and the larger the quantity of the UV-LED lamp beads are, the larger the irradiation dose of deep ultraviolet rays is during sterilization.
Specifically, the UV-LED light source can emit deep ultraviolet light with the wavelength of UVC wave band (200-280 nm), the deep ultraviolet light can penetrate cell walls and spores of microorganisms such as bacteria, viruses, fungi, molds and the like, and the molecular structure of deoxyribonucleic acid or ribonucleic acid in cells of a microorganism organism is destroyed to ensure that the growing cells and/or the regenerative cells die, so that the sterilization effect is achieved. Compared with the traditional ultraviolet mercury lamp, the UV-LED lamp has the advantages that no residue is generated when the UV-LED lamp is used for sterilization, and no heavy metal pollution is caused due to the breakage of the lampshade, so that the UV-LED lamp is safer to use and can be suitable for any occasions.
Further, the arrangement of the UV-LED beads 101 on the light source board 102 can be flexibly adjusted according to the required killing area. Referring to fig. 5, when the number of the UV-LED lamp beads is 9, the lamp beads may be arranged in 3 × 3, and the arrangement may uniformly distribute the lamp beads on the light source plate, and increase the sterilizing area by fully using the light source plate, thereby improving the sterilizing efficiency. Of course, in practical application, the lamp beads can be arranged in a triangular shape or a circular shape according to requirements, and this is not specifically limited in the embodiment of the present application.
In addition, in the portable sterilization apparatus provided by the embodiment of the application, the heat sink 103 and the fan 104 are simultaneously arranged in the main body casing 20, so that the sterilization equipment can quickly dissipate heat in the operation process, and the problem that the service life of the sterilization apparatus is affected due to poor heat dissipation is effectively solved.
Optionally, referring to fig. 2 and fig. 4, the portable sterilization device further includes a detachable reflective cup 109;
one side of the detachable light reflecting cup 109, which faces the UV-LED lamp bead 101, is provided with a first magnet 110, the lampshade 10 is provided with a second magnet 111, and the detachable light reflecting cup 109 is fixed with the lampshade 10 through the first magnet 110 and the second magnet 111.
Specifically, one side of the detachable reflection cup 109 facing the UV-LED lamp bead 101 is provided with a first groove, the first magnet 110 is fixed in the first groove through a screw, the lamp shade 10 is provided with a second groove, and the second magnet 111 is fixed in the second groove through glue. When the reflective cup 109 is installed, only the first magnet 110 and the second magnet 111 need to be attracted, and the operation is very simple. In some other embodiments of the present application, the first magnet and the first groove may be fixed in other manners, and are not limited to screw fixation; the second magnet and the second groove are not limited to the glue fixing manner, and other feasible fixing manners can be adopted, which is not specifically limited in the present application.
In this embodiment, the user can calibrate the sterilization distance by using the reflective cup 109 during sterilization. Illustratively, if the height of the reflector cup is 50mm, it means that the virus can be effectively killed if the sterilizing device is properly used within the sterilizing distance.
