Example one

Referring to fig. 1 and 2, a sterilization apparatus 100 for sterilizing air passing through the sterilization apparatus 100 is provided in this embodiment.

The sterilization device 100 provided by the present application comprises an ultraviolet lamp module 110, two oppositely disposed cover plates 120 and two reflecting layers 130, wherein an overflowing chamber 120b allowing air to flow is formed between the two oppositely disposed cover plates 120, both cover plates 120 are provided with air holes 120a, and the air holes 120a are communicated with the overflowing chamber 120 b. Wherein, the two cover plates 120 are provided with a reflective layer 130 on the opposite surfaces. The uv lamp module 110 is disposed on one of the cover plates 120, and the uv lamp module 110 can emit uv rays toward the overflowing chamber 120b, and the uv rays irradiated to the reflective layer 130 are reflected.

Further, for more clearly describing the technical solution of the present embodiment, two cover plates 120 are defined as a first cover plate 121 and a second cover plate 122, respectively, the air hole 120a formed on the corresponding first cover plate 121 is a first air hole 1210, and the air hole 120a formed on the corresponding second cover plate 122 is a second air hole 1220.

Optionally, the first cover plate 121 and the second cover plate 122 are adapted in shape, i.e. can be cylindrical, prismatic or other shapes. The first air hole 1210 and the second air hole 1220 may have other shapes such as a circle, a square, or a hexagon.

The first cover plate 121 includes first and second opposite sides 121a and 121b, and the second cover plate 122 includes third and fourth opposite sides 122a and 122 b. The first side 121a of the first cover plate 121 and the third side 122a of the second cover plate 122 are close to each other, and the second side 121b of the first cover plate 121 and the fourth side 122b of the second cover plate 122 are far from each other.

Further, the first cover plate 121 and the second cover plate 122 are connected by clamping or screws, so that the assembly, disassembly and maintenance are facilitated.

Referring to fig. 2, 3 and 5, a first groove 121c is concavely formed on the first side surface 121a toward the inside of the first cover plate 121, a second groove 122c is concavely formed on the third side surface 122a toward the second cover plate 122, and when the first side surface 121a and the third side surface 122a approach each other, the first groove 121c and the second groove 122c cooperate to form the flow-through chamber 120b allowing air to flow. The first air hole 1210 on the first cover plate 121 and the second air hole 1220 on the second cover plate 122 are both communicated with the overflowing chamber 120b, so that air can enter the overflowing chamber 120b from the first air hole 1210 and then flow out from the second air hole 1220; alternatively, air can enter the overflowing chamber 120b from the second air hole 1220 and then flow out of the first air hole 1210.

Referring to fig. 4 and 6, further, the first cover plate 121 has a plurality of first air holes 1210, the plurality of first air holes 1210 are uniformly distributed on the second side surface 121b of the first cover plate 121, the second cover plate 122 has a plurality of second air holes 1220, and the plurality of second air holes 1220 are uniformly distributed on the fourth side surface 122b of the second cover plate 122, so as to ensure that the air can smoothly enter the flow-through chamber 120b and smoothly flow out of the flow-through chamber 120 b.

Alternatively, adjacent first air holes 1210 and second air holes 1220 are offset from each other, so that air does not directly pass through the first air holes 1210 and the second air holes 1220, but the path of the flow of air entering the flow-passing chamber 120b is relatively far, thereby increasing the flow time of air in the flow-passing chamber 120 b.

Referring to fig. 2, fig. 3 and fig. 5, in the present embodiment, two reflective layers 130 are defined as a first reflective layer 131 and a second reflective layer 132. The first reflective layer 131 is disposed at the bottom of the first groove 121c on the first side surface 121a or disposed at the bottom and the peripheral sidewalls of the first groove 121 c. The second reflective layer 132 is disposed on the bottom of the second recess 122c or the bottom and the peripheral sidewall of the second recess 122c on the third side surface 122 a.

It should be understood that since the first side 121a of the first cover plate 121 and the third side 122a of the second cover plate 122 are oppositely disposed, the first reflective layer 131 at the bottom of the first groove 121c and the second reflective layer 132 at the bottom of the second groove 122c are also oppositely disposed.

Alternatively, the first and second reflective layers 131 and 132 are formed on the corresponding first and second cover plates 121 and 122 by coating. Alternatively, the first and second reflective layers 131 and 132 are both disposed on the corresponding first and second cover plates 121 and 122 by bonding.

Referring to fig. 1, fig. 2 and fig. 4, the ultraviolet lamp module 110 includes a predetermined number of ultraviolet LED strips 111, and the predetermined number of ultraviolet LED strips 111 are disposed on the first cover plate 121 or the second cover plate 122. In this embodiment, a preset number of ultraviolet LED strips 111 are disposed on the second side 121b of the first cover plate 121. It can be understood that the number of the ultraviolet LED strips 111 is determined by the area of the second side surface 121b, and the number of the ultraviolet LED strips 111 is not limited in this embodiment.

Specifically, each ultraviolet LED lamp strip 111 is provided with a plurality of LED lamp beads, and the LED lamp beads can emit ultraviolet rays. A mounting groove 1212 is formed on the second side surface 121b of the first cover plate 121 corresponding to each ultraviolet LED strip 111, and the mounting groove 1212 and the first air hole 1210 do not interfere with each other. A light hole 1213 corresponding to the LED lamp bead is formed in the mounting groove 1212, the light hole 1213 penetrates from the second side surface 121b to the first side surface 121a, and a through hole 131a is formed in the first reflective layer 131 corresponding to the light hole 1213. Therefore, ultraviolet rays emitted by each LED lamp bead sequentially pass through the corresponding light transmission hole 1213 and the through hole 131a, and directly irradiate on the second reflective layer 132 on the second cover plate 122.

It can be understood that, in this embodiment, the LED lamp bead emitting ultraviolet rays is adopted, and the LED lamp bead is used as a continuous radiation energy generator, and the emitted spectrum is invisible light, but still belongs to a form of a light beam, that is, conforms to the reflection principle of light. Since the first reflective layer 131 and the second reflective layer 132 are disposed opposite to each other, the ultraviolet rays are reflected uninterruptedly between the first reflective layer 131 and the second reflective layer 132 until the energy is exhausted. Meanwhile, the LED lamp beads continuously emit energy, and the LED lamp beads and the light rays still reflected show a superposed state effect, so that the radiation energy is maximized, and further, the air flowing through the overflowing chamber 120b is better sterilized and disinfected to kill bacteria and viruses in the air.

Further, the adjacent first air holes 1210 and the second air holes 1220 are staggered with each other, so that the flowing time of the air in the overflowing chamber 120b is increased, that is, the radiation time and the sterilization time of ultraviolet rays to the air are increased, and the sterilization effect is further improved.

Of course, there is a case where a very small amount of ultraviolet rays is reflected into the first air holes 1210 and the second air holes 1220 to interrupt the reflection, which does not affect the sterilization effect.

Referring to fig. 2, fig. 3 and fig. 5, in the present embodiment, the first reflective layer 131 and the second reflective layer 132 are both diffuse reflective layers, and the diffuse reflective layers have diffuse reflective surfaces. Therefore, when the ultraviolet rays irradiate or reflect to the diffuse reflection surface of the diffuse reflection layer, the ultraviolet rays can be subjected to diffuse reflection on the diffuse reflection surface, a multidirectional scattering mode is further presented, energy is prevented from being concentrated in one direction too much, therefore, the radiation rays can be distributed in the whole overflowing chamber 120b more uniformly through diffuse reflection, the radiation energy is retained in the overflowing chamber 120b to the maximum extent, the utilization rate of the ultraviolet rays is greatly improved, and the purpose of efficient sterilization is achieved.

Furthermore, the diffuse reflection layer is provided with the diffuse reflection surfaces with alternate concave and convex, namely the concave and convex of the diffuse reflection surfaces are fluctuated, so that the air flowing through the diffuse reflection surfaces is fluctuated along with the fluctuation of the diffuse reflection surfaces to disturb the air in the overflowing cavity, the flowing air forms a turbulent state, and the path through which the air passes is prolonged by the relatively flat reflection surfaces, so that the air retention time is prolonged.

Therefore, in this embodiment, the first reflective layer 131 and the second reflective layer 132 are designed to be in a diffuse reflection mode, which not only has an optical effect, but also has a retention effect on the influence of the air flow, so that the time for the air to pass through the sterilization device 100 can be prolonged, and the sterilization effect of the module is further enhanced.

Of course, in some embodiments, the first reflective layer 131 or the second reflective layer 132 is a diffuse reflective layer, for example, the first reflective layer 131 is a diffuse reflective layer, and the second reflective layer 132 is a specular reflective layer, which also achieves the sterilization effect. It should be understood that the foregoing is illustrative only and is not intended to limit the scope of the invention.

Optionally, the diffuse reflection surface of the diffuse reflection layer is an undulating arc surface, a concave-convex diamond surface, a honeycomb surface or other non-full plane surface. It should be understood that the foregoing is illustrative only and is not intended to limit the scope of the invention.

It should be noted that, in the prior art, there is an air sterilizer using an ultraviolet mercury lamp, which basically adopts a direct irradiation method, does not effectively use the optical principle, and fails to maximize the energy utilization rate, and because the energy of the mercury lamp is relatively strong, and the mercury lamp is in the form of a lamp tube, the optical design is relatively inelastic, and because the gaseous mercury in the mercury lamp belongs to a lethal neurotoxic toxic gas. Therefore, the lamp bead adopting the LED solid state in the embodiment has higher relative safety in emitting ultraviolet rays. Further considering that the efficiency of converting the existing LED lamp beads into ultraviolet radiation is still low, an optical design mode is provided by combining the embodiment to increase the utilization rate of energy, so that a relatively safe and effective sterilization product is designed under the advantages of design flexibility and flexibility of the structure of the LED lamp beads.

Meanwhile, air is a fluid, and when air becomes a subject to be sterilized, attention needs to be paid to the flowing speed of the air, and the flow rate affects the success rate of air sterilization, so that the sterilization device 100 provided by the embodiment can retain the residence time of the air to a certain extent, affect the flow rate but not affect the flow rate, and further, can maximize the ultraviolet sterilization energy efficiency and exert the safety advantage of the sterilization device at the same time.

Example two

Referring to fig. 2 to fig. 6, the present embodiment provides a sterilization apparatus 100, which is an improvement based on the first embodiment, and is different from the first embodiment in that:

referring to fig. 3 and 4, in the present embodiment, a first air guide sleeve 1211 is disposed on the first cover plate 121 corresponding to the first air hole 1210, the first air guide sleeve 1211 is located at the bottom of the first groove 121c and extends in a direction away from the second side surface 121b, and an air guide channel is disposed in the first air guide sleeve 1211 and is communicated with the first air hole 1210.

Referring to fig. 5 and 6, a second air guide sleeve 1221 is disposed on the second cover plate 122 corresponding to the second air hole 1220, the second air guide sleeve 1221 is located at the bottom of the second recess 122c and extends in a direction away from the fourth side 122b, and an air guide channel is disposed in the second air guide sleeve 1221 and is communicated with the second air hole 1220.

Referring to fig. 2, when the first cover plate 121 and the second cover plate 122 are disposed opposite to each other, the opening of the first air guide sleeve 1211 faces the bottom of the second recess 122c, and the opening of the second air guide sleeve 1221 faces the bottom of the first recess 121 c. For example, air enters from the first air hole 1210, is guided to the bottom of the second groove 122c by the air guide channel of the first air guide sleeve 1211, and air with a certain flow rate collides with the bottom of the second groove 122c and then is diffused all around, so that the air is uniformly dispersed in the overflowing chamber 120b, and the sterilization effect is improved. In addition, the air in the overflowing chamber 120b enters the air guide channel from the opening of the second air guide sleeve 1221 and then is discharged from the second air holes 1220, so that the path of the air can be extended, the sterilization duration can be increased, and the sterilization effect can be improved. Of course, air is introduced from the second air hole 1220, and the effect of air discharged from the first air hole 1210 is the same, and will not be described herein.

Referring to fig. 3 and 5, further, a first reflecting layer 131 is correspondingly disposed on the outer side surface of the first air guide sleeve 1211, and a second reflecting layer 132 is correspondingly disposed on the second air guide sleeve 1221, so that when ultraviolet rays are reflected to the outer side surfaces of the first air guide sleeve 1211 and the second air guide sleeve 1221, the ultraviolet rays can be further reflected, and the ultraviolet rays are more uniformly dispersed in the overflowing chamber 120b, thereby improving the utilization rate of the ultraviolet rays and enhancing the sterilization effect.

In some embodiments, the air is filtered by the filter element assembly, sterilized and disinfected by the first air holes 1210 of the first cover plate 121 through the flow chamber 120b, and exhausted from the second air holes 1220 of the second cover plate 122.
