Description

Technical Field

[0001] This application relates to the technical field of LEDs, and particularly to a sterilization module. Background Art

[0002] Ultraviolet rays have a sterilizing effect and can kill bacteria, spores, mycobacteria, coronaviruses, fungi, etc. Ultraviolet sterilization modules are widely used for sterilizing and disinfecting water quality, air, and the surfaces of objects. Currently, only LED (light-emitting diode) ultraviolet lamp beads are provided in the sterilization module. When the sterilization module is used in a dark environment, additional lighting fixtures are required for illumination, which is very inconvenient.

[0003] Therefore, how to solve the above technical problems should be the focus of attention of those skilled in the art. Summary of the Invention

[0004] The purpose of this application is to provide a sterilization module that has both sterilization and lighting functions and prolongs the service life of the lighting lamp beads.

[0005] To solve the above technical problems, this application provides a sterilization module, including:

[0006] A main body structural member having an opening;

[0007] A substrate disposed at the opening;

[0008] Lamp beads disposed on the substrate and within the main body structural member, the lamp beads including ultraviolet lamp beads and lighting lamp beads;

[0009] A transparent plate disposed within the main body structural member and opposite to the lamp beads, a first through hole being provided in a region of the transparent plate corresponding to the ultraviolet lamp beads, and ultraviolet rays being unable to penetrate the transparent plate.

[0010] Optionally, it further includes:

[0011] An optical reflection device disposed on the substrate, the optical reflection device including a connected optical reflection cavity and a receiving cavity, the lamp beads and the transparent plate being located in the receiving cavity.

[0012] Optionally, the shape of the optical reflection cavity is horn-shaped.

[0013] Optionally, it further includes:

[0014] A quartz glass plate disposed at the light outlet within the main body structural member.

[0015] Optionally, the main structural member includes a column body with a threaded hole provided therein. The substrate is provided with a second through hole matching the column body. A pressing ring is arranged on the outer side of the column body. The substrate and the main body are connected by screws and the pressing ring.

[0016] Optionally, it further includes:

[0017] A first sealing ring arranged between the periphery of the quartz glass plate and the main structural member.

[0018] Optionally, a concave counterbore matching the installation positioning posts at the installation position of the sterilization module is provided on the front surface of the main structural member.

[0019] Optionally, it further includes:

[0020] A second sealing ring arranged between the main structural member and the installation hole at the installation position.

[0021] Optionally, it further includes:

[0022] Indicator beads arranged on the substrate.

[0023] Optionally, it further includes:

[0024] Control and driving devices arranged on the substrate.

[0025] A sterilization module provided by the present application includes: a main structural member with an opening; a substrate arranged at the opening; lamp beads arranged on the substrate and located inside the main structural member, the lamp beads including ultraviolet lamp beads and lighting lamp beads; a transparent plate arranged inside the main structural member and opposite to the lamp beads, a first through hole is provided in the area of the transparent plate corresponding to the ultraviolet lamp beads, and ultraviolet rays cannot penetrate the transparent plate.

[0026] It can be seen that the sterilization module in the present application includes a main structural member, a substrate, lamp beads and a transparent plate. The lamp beads include ultraviolet lamp beads and lighting lamp beads. A first through hole is provided in the area of the transparent plate corresponding to the ultraviolet lamp beads. The ultraviolet rays emitted by the ultraviolet lamp beads irradiate to the outside of the sterilization module through the first through hole to achieve the sterilization effect. The lighting lamp beads emit light for illumination. Therefore, the sterilization module has the functions of sterilization and lighting at the same time; the ultraviolet rays directly irradiated or reflected by the ultraviolet lamp beads will affect the lighting lamp beads and accelerate the aging of the lighting lamp beads, greatly shortening the service life of the lighting lamp beads. Since ultraviolet rays cannot penetrate the transparent plate, the transparent plate can block the reflected ultraviolet rays, thereby prolonging the service life of the lighting lamp beads and improving the quality of the sterilization module.

[0031] In order to enable those skilled in the art to better understand the solution of the present application, the following further details the present application in conjunction with the drawings and specific implementation manners. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of them. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0032] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0033] As described in the background art section, currently only LED ultraviolet lamp beads are provided in the sterilization module. When the sterilization module is used in a dark environment, additional lighting fixtures need to be used for lighting, which is very inconvenient.

[0034] In view of this, the present application provides a sterilization module. Please refer to Figure 1 , Figure 1 A cross-sectional view of a sterilization module provided by an embodiment of the present application, including:

[0035] A main body structural member 1 having an opening;

[0036] A substrate 2 disposed at the opening;

[0037] Lamp beads disposed on the substrate 2 and within the main body structural member 1, the lamp beads including ultraviolet lamp beads 3 and illumination lamp beads 4;

[0038] A transparent plate 5 is disposed within the main structural member 1 and is disposed opposite to the lamp beads. The transparent plate 5 is provided with a first through hole 51 in the area corresponding to the ultraviolet lamp beads 3, and ultraviolet rays cannot penetrate the transparent plate 5.

[0039] In this application, the material of the main structural member 1 is not limited. For example, it can be metal, ordinary glass, polytetrafluoroethylene (PTFE), etc.

[0040] Wires are provided on the substrate 2, and the lamp beads are electrically connected to the substrate 2. At the same time, the substrate 2 has a heat dissipation function. The substrate 2 includes but is not limited to a ceramic substrate 2, a BT (Bismaleimide Triazine) board, and a metal board.

[0041] It should be noted that in this application, the type of the ultraviolet lamp beads 3 is not limited and is determined according to the required wavelength of ultraviolet rays. For example, the ultraviolet lamp beads 3 can be UVA LED lamp beads, or UVB LED lamp beads, or UVC LED lamp beads.

[0042] The illuminating lamp beads 4 are generally white light LED lamp beads. In this application, the connection method between the illuminating lamp beads 4 and the substrate 2 is not limited. For example, the illuminating lamp beads 4 can be connected to the substrate 2 in a conventional packaging form, or in a eutectic packaging form. Since ultraviolet irradiation can damage all materials except metal, glass, and PTFE, causing them to turn yellow and crack, in order to prevent ultraviolet rays from damaging the illuminating lamp beads 4 and causing the colloid in the illuminating lamp beads 4 to crack, preferably, the illuminating lamp beads 4 are connected to the substrate 2 in a eutectic packaging form.

[0043] The purpose of setting the transparent plate 5 is to ensure that the light emitted by the illuminating lamp beads 4 can pass through the transparent plate 5 to achieve illumination. Optionally, the transparent plate 5 can be an ordinary glass plate, or the transparent plate 5 is an ultraviolet-resistant plastic plate.

[0044] In this application, the arrangement of the ultraviolet lamp beads 3 and the illuminating lamp beads 4 is not limited and depends on the situation. For example, the illuminating lamp beads 4 surround the outside of the ultraviolet lamp beads 3. At this time, the transparent plate 5 is an annular plate, or the illuminating lamp beads 4 and the ultraviolet lamp beads 3 are arranged at intervals, etc.

[0045] One side of the main structural member 1 opposite to the lamp beads is the light outlet.

[0046] The sterilization module in this application includes a main structural member 1, a substrate 2, lamp beads, and a transparent plate 5. The lamp beads include an ultraviolet lamp bead 3 and a lighting lamp bead 4. The area of the transparent plate 5 corresponding to the ultraviolet lamp bead 3 is provided with a first through hole 51. The ultraviolet rays emitted by the ultraviolet lamp bead 3 irradiate to the outside of the sterilization module through the first through hole 51 to achieve the sterilization effect, and the lighting lamp bead 4 emits light for illumination. Therefore, the sterilization module has both sterilization and lighting functions; the ultraviolet rays directly irradiated or reflected by the ultraviolet lamp bead 3 will affect the lighting lamp bead 4, accelerating the aging of the lighting lamp bead 4 and significantly shortening the service life of the lighting lamp bead 4. Since ultraviolet rays cannot penetrate the transparent plate 5, the transparent plate 5 can block the reflected ultraviolet rays, thereby extending the service life of the lighting lamp bead 4 and improving the quality of the sterilization module.

[0047] To facilitate the staff to understand whether the sterilization module is working or not, the sterilization module further includes:

[0048] An indicator lamp bead disposed on the substrate 2.

[0049] The indicator lamp bead can be a lamp bead that emits red light, blue light, or other colors. When the sterilization module is working, the indicator lamp bead lights up.

[0050] Preferably, the indicator lamp bead is connected to the substrate 2 in a eutectic encapsulation form to prevent the ultraviolet rays from damaging the indicator lamp bead and causing the colloid inside the indicator lamp bead to crack.

[0051] Since ultraviolet rays are easily blocked and absorbed by ordinary materials, resulting in waste of some ultraviolet rays and reduced sterilization efficiency. To improve the utilization rate of ultraviolet rays and the sterilization efficiency, in an embodiment of this application, please refer to Figure 2 , Figure 2 which is a cross-sectional schematic diagram of another sterilization module provided by the embodiment of this application. On the basis of the above embodiment, the sterilization module further includes:

[0052] An optical reflection device 6 disposed on the substrate 2. The optical reflection device 6 includes a connected optical reflection cavity 61 and a receiving cavity 62. The lamp beads and the transparent plate 5 are located in the receiving cavity 62.

[0053] For the part of the ultraviolet rays originally absorbed by the inner wall of the main structural member 1 emitted by the ultraviolet lamp bead 3, on the surface of the optical reflection device 6, that is, in the optical reflection cavity 61, reflection occurs and is emitted through the light outlet for utilization, improving the sterilization efficiency.

[0054] The material of the optical reflection device 6 can be PTFE, and PTFE has a small density to reduce the weight of the sterilization module.

[0055] In order to enhance the reflection of part of the ultraviolet rays that were originally absorbed by the inner wall of the main structural member 1 and further improve the utilization rate of this part of the ultraviolet rays, the shape of the optical reflection cavity 61 is trumpet-shaped.

[0056] Furthermore, the sterilization module further includes a quartz glass plate 7 disposed at the light outlet in the main structural member 1.

[0057] The transmittance of ultraviolet rays in the quartz glass plate 7 is the highest, which can improve the emission rate of ultraviolet rays, enhance the sterilization efficiency of the sterilization module, and at the same time achieve the effect of dust prevention. The closer the ultraviolet lamp beads 3 are to the quartz glass plate 7, the closer the ultraviolet lamp beads 3 are to the object to be irradiated, and the better the sterilization effect.

[0058] Optionally, the main structural member 1 includes a column 11 with a screw hole provided therein. The substrate 2 is provided with a second through hole 21 matching the column 11. A compression ring 8 is disposed outside the column 11. The substrate 2 and the main body structure are connected by screws 13 and the compression ring 8.

[0059] The column 11 passes through the second through hole 21 of the substrate 2, and then the screw 13 is screwed into the screw hole of the column 11. By tightening the screw 13, pressure is applied to the compression ring 8, thereby pressing the substrate 2 tightly, realizing the connection between the substrate 2 and the main structural member 1, and enhancing the firmness of the connection between the substrate 2 and the main structural member 1.

[0060] However, the present application does not specifically limit the connection manner between the substrate 2 and the main structural member 1. As other embodiments, the substrate 2 and the main structural member 1 can also be connected by an adhesive method.

[0061] Furthermore, the sterilization module further includes:

[0062] A first sealing ring 9 disposed between the periphery of the quartz glass plate 7 and the main structural member 1.

[0063] The first sealing ring 9 includes but is not limited to a white sealing ring, a black sealing ring, a yellow sealing ring, and sealing rings of any other color. Preferably, it is a white sealing ring to facilitate the reflection of ultraviolet rays.

[0064] The function of providing the first sealing ring 9 is that when the screw 13 is screwed into the screw hole of the column 11 and pressure is applied to the compression ring 8, the pressure will gradually press the substrate 2, the optical reflection device 6, the quartz glass plate 7, the first sealing ring 9, and the main structural member 1 tightly, causing the first sealing ring 9 to be deformed by extrusion, achieving the waterproof effect.

[0065] In the sterilization module in the related art, an external thread is designed on the main structural member 1, and then a locking nut is additionally designed to fix the main structural member 1 at the installation position A. This not only increases the material cost of installation but also is prone to loosening. In order to reduce the cost of the sterilization module, in the sterilization module of the present application, a concave counterbore 12 matching the installation positioning post at the installation position A of the sterilization module is provided on the front surface of the main structural member 1. A screw hole is provided in the installation positioning post, and the installation positioning post is inserted into the concave counterbore 12 so that a screw 13 fastened on the back surface of the main structural member 1 can be used for fixation, saving the structural part cost of the locking nut.

[0066] Among them, the front surface of the main structural member 1 is the light-emitting surface.

[0067] In the present application, the number of the concave counterbores 12 is not limited. For example, two, three, four or even more. Preferably, the number of the concave counterbores 12 is three. At this time, the bottom view of the sterilization module is as Figure 3 shown. The concave counterbores 12 are arranged in a triangular layout, which can ensure the firmness of the connection between the main structural member 1 and the installation position A while reducing the usage amount of the screws 13. The sterilization module is powered on through a wire.

[0068] Furthermore, the sterilization module further includes:

[0069] A second sealing ring 10 arranged between the main structural member 1 and the installation hole at the installation position A.

[0070] During installation, the main structural member 1 is placed into the installation hole. Since the second sealing ring 10 is provided between the main structural member 1 and the installation hole, the screw 13 is placed into the installation positioning post. When the main structural member 1 is locked with the installation hole by the screw 13, the second sealing ring 10 will be deformed at this time to achieve the waterproof function.

[0071] Based on any of the above embodiments, in an embodiment of the present application, the sterilization module further includes: a control and driving device arranged on the substrate 2 to control the lighting and extinguishing working conditions of the lamp beads.

[0072] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is the difference from other embodiments. The same or similar parts among the embodiments can be referred to each other. For the device disclosed in the embodiment, since it corresponds to the method disclosed in the embodiment, the description is relatively simple, and the relevant parts can be referred to the description of the method part.

[0073] The above has introduced the sterilization module provided by this application in detail. Specific examples are used in this text to elaborate on the principle and implementation manner of this application. The description of the above embodiments is only used to help understand the method and its core idea of this application. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of this application, several improvements and modifications can be made to this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
