Description

Technical Field

[0001] The utility model relates to the technical field of disinfection and sterilization, in particular to an ultraviolet lamp module with a replaceable light source. Background Art

[0002] Public places such as stations, hospitals, supermarkets, and schools are crowded areas and are prone to disease and virus transmission, so they need to be disinfected frequently. The most widely used ultraviolet lamps are mainly mercury ultraviolet lamps, which have a sterilization band of 253.7nm, an irradiation intensity of 200 at 1m, and an effective distance of 5m. They are usually used in the field of air disinfection, because mercury ultraviolet lamps are contaminated by mercury when they are broken or scrapped. Therefore, new ultraviolet lamps, such as LED ultraviolet lamps, pulsed ultraviolet lamps, and excimer ultraviolet lamps are new research directions.

[0003] The intensity of a single LED UV lamp is too low. Generally, within an effective distance of 10 cm, multiple LED UV lamps form a light board to irradiate the surface of objects at close range, which can achieve effective sterilization. The current cost of LED UV lamps is relatively high, and the heat dissipation problem of LED UV lamps must also be considered. The industry needs to further study how to improve the conversion rate of electro-optical.

[0004] Pulse UV lamps can emit high-energy, wide-spectrum 200-1100nm light waves, with high sterilization efficiency, higher than existing mercury UV lamps. However, the cost is high, and the life of the main component, the pulsed xenon lamp, is short, which is suitable for special disinfection and sterilization needs.

[0005] Excimer UV lamp is the technology that is closest to mercury UV lamp at present. The central band of excimer UV lamp is 222nm ultraviolet. Domestic and foreign academics and experts have confirmed that this technology can achieve good sterilization effect and can also achieve human-machine coexistence for a certain period of time. At present, it is in the early stage of industry development, and it may be a hot spot in the field of disinfection to replace mercury UV lamp in the future.

[0006] The new type of UV lamp with a specific wavelength has a lifespan of about 3,000 hours. Due to the technical characteristics of the product, filters, reflective aluminum, air cooling, and fixed connections of conductive components are used in the design of the finished product, resulting in the inconvenience of disassembling and replacing the lamp due to the fixed structure. Once the lamp reaches the specified lifespan, the entire machine is scrapped and a new one needs to be purchased, resulting in a waste of components and is not conducive to energy conservation and environmental protection. Utility Model Content

[0007] In order to solve the problems in the prior art, the utility model provides an ultraviolet lamp module with a replaceable light source, in which only the part with affected life span is replaced, thereby achieving the reuse of other parts and saving use costs.

[0008] The utility model discloses an ultraviolet lamp module with a replaceable light source, comprising a base and an ultraviolet lamp body, wherein the base and the ultraviolet lamp body are provided with detachable structures that cooperate with each other, the base and the ultraviolet lamp body are detachably connected via the detachable structure, the base is provided with a conductive ejector pin and a wiring structure for supplying power to the ultraviolet lamp body, the wiring structure is used for embedding an external power line that can be electrically connected to the conductive ejector pin, and also includes a bottom cover that seals the conductive ejector pin.

[0009] Furthermore, the ultraviolet lamp body includes an intermediate connecting member, a front cover, and a light source module arranged between the intermediate connecting member and the front cover, the detachable joint is arranged on a side of the intermediate connecting member away from the front cover, the front cover is provided with a light emitting hole, and the light of the light source module is emitted from the light emitting hole.

[0010] Furthermore, the intermediate connecting member and the front cover are detachably connected via threads.

[0011] Furthermore, the light source module includes a light source, a first electrode and a second electrode respectively connected to the positive and negative poles of the conductive pin, the light source module is provided with a planar light emitting surface corresponding to the light emitting hole of the front cover, a filter layer is provided on the planar light emitting surface, the light source is filled with an inert gas for luminescence, the first electrode and the second electrode excite the inert gas to emit ultraviolet rays, and the light is emitted through the planar light emitting surface.

[0012] Furthermore, the light source is in the shape of a pancake, including an arc surface arranged on the side of the light source, and a first plane and a plane light-emitting surface respectively arranged on both sides of the arc surface; the first electrode matches the size of the arc surface and is wrapped around the outer wall of the arc surface; and the second electrode covers the first plane.

[0013] Furthermore, a UV reflection layer is disposed on a side of the first electrode and the second electrode close to the light source.

[0014] Furthermore, a heat dissipation conductive member which is arranged in contact with the second electrode is provided on a side of the second electrode away from the light source, and a conductive connecting member which is connected to the first electrode is provided at the bottom of the intermediate connecting member.

[0015] Furthermore, the detachable structure is a threaded connection structure.

[0016] Furthermore, a positioning member for limiting the rotation of the threaded connection structure is also provided on the base, and the positioning member includes a positioning surface matched with the outer side wall of the detachable structure of the ultraviolet lamp body, and a buckle engaged with the base.

[0017] Furthermore, it also includes a heat dissipation structure arranged on the base.

[0018] Compared with the prior art, the utility model has the following beneficial effects: by setting the ultraviolet lamp module as a detachable base and ultraviolet lamp body, when the lamp body cannot be used normally, only the ultraviolet lamp body needs to be replaced, and no additional wiring operations are required. On the one hand, lossless connection and separation can be quickly performed to achieve convenient and fast replacement of the light source. On the other hand, compared with the scrapping of the entire machine, the base part can be reused, which is more energy-saving and emission-reducing. The user only needs to purchase the ultraviolet lamp body for replacement, which effectively reduces the user's use cost.

[0019] By setting the detachable structure as a threaded connection structure, the poor conductive contact caused by errors in the processing of the ultraviolet lamp body can be effectively eliminated, so that the conductive ejector pin can be in stable contact with the conductive element in the ultraviolet lamp body, greatly reducing the defective rate of the product; by setting a positioning piece, the rotational position of the ultraviolet lamp body can be positioned, further ensuring the stability of the conductive connection.

[0020] By arranging the ultraviolet lamp body as an intermediate connecting piece and a front cover, and detachably connecting the intermediate connecting piece and the front cover through a thread, the error of the light source can be eliminated by the rotation height of the thread, and the poor contact between the second electrode and the heat dissipation conductive piece, and between the heat dissipation conductive piece and the conductive ejector pin in the ultraviolet lamp body caused by the size error of the light source can be avoided. Moreover, without adopting other fixing structures, the first electrode, the second electrode and other conductive elements can be firmly pressed in the intermediate connecting piece, and the assembly is simpler and more convenient.

[0021] Except for the flat light-emitting surface, the ultraviolet reflection layers on other surfaces of the ultraviolet lamp body can emit all the reflected light through the flat light-emitting surface, further increasing the irradiation intensity and improving the sterilization and disinfection effect;

[0022] The utility model realizes single-side light emission through the structure, and the light-emitting surface is flat, so it is easy to realize vacuum mounting or coating of the filter layer to obtain an optional effective wavelength without clutter. The coating method greatly reduces the production cost, which is conducive to the popularization of ultraviolet excimer lamps with specific wavelengths. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments.

[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0030] like Figure 1-Figure 4 As shown, the ultraviolet lamp module with replaceable light source of the utility model includes a base 200 and an ultraviolet lamp body 100, wherein the base 200 and the ultraviolet lamp body 100 are provided with mutually cooperating detachable structures, and the base 200 and the ultraviolet lamp body 100 are detachably connected through the detachable structure, and the base 200 is provided with a conductive ejector pin 500 and a wiring structure 205 for supplying power to the ultraviolet lamp body, the conductive ejector pin 500 is fixed in an ejector pin hole 206 on the base, and the end thereof extends out of the ejector pin hole 206 and is connected to the conductive structure on the ultraviolet lamp body 100, and the wiring structure 205 is used for embedding an external power line that can be electrically connected to the conductive ejector pin 500, and also includes a bottom cover 300 that seals the conductive ejector pin 500. Of course, the bottom cover 300 of this example can also be provided integrally with the base 200, and the power line passes through one side of the base 200 for connecting to an external power source.

[0031] In this example, a clamping hole 302 is provided on the bottom cover 300 , and a clamping member 204 is provided on the base 200 . The bottom cover 300 and the base 200 are fixedly connected through the cooperation of the clamping hole 302 and the clamping member 204 .

[0032] like Figure 2 As shown, this example also includes a heat dissipation structure 600 disposed on the base. Preferably, the heat dissipation structure 600 of this example is a heat dissipation fan, and a stud 301 for fixing the heat dissipation fan is also provided on the bottom cover 300. The heat dissipation structure of this example can also be set as an insulating block with good thermal conductivity. This example can also be provided with a driving element connected to the conductive ejector pin 500, such as a ballast.

[0033] This example also has a fixing member 201 for fixing the entire ultraviolet lamp module. The fixing member 201 can be a fixing hole, or a connecting ear structure with a fixing hole.

[0034] like Figure 1-Figure 4 As shown, preferably, the detachable structure of this example is a threaded connection structure, an external thread is provided under the base 200, and an internal thread matching the external thread is provided on the ultraviolet lamp body 100. By setting the detachable structure as a threaded connection structure, the poor conductive contact caused by errors in the processing of the ultraviolet lamp body can be effectively eliminated, so that the conductive pin can be in stable contact with the conductive element in the ultraviolet lamp body, which greatly reduces the defective rate of the product; by setting a positioning piece, the rotational position of the ultraviolet lamp body can be positioned, further ensuring the stability of the conductive connection.

[0035] Preferably, the base 200 of this example is also provided with two positioning members 400 for limiting the rotation of the threaded connection structure, the positioning member 400 includes a positioning surface that cooperates with the outer side wall of the detachable structure of the ultraviolet lamp body 100, the base 200 is provided with an extension surface 202 facing the ultraviolet lamp body 100, the extension surface 202 is provided with a snap-on structure 203, and the positioning member 400 is provided with a buckle that is snap-on with the snap-on structure 203. When the thread of the detachable structure is rotated into place, the positioning surface of the positioning member 400 and the outer side of the ultraviolet lamp body 100 are prevented from poor contact due to loosening of the thread caused by factors such as vibration.

[0036] As a preferred embodiment of the utility model, the ultraviolet lamp body 100 of this example includes an intermediate connector 101, a front cover 102, and a light source module arranged between the intermediate connector 101 and the front cover 102, the detachable joint is arranged on a side of the intermediate connector 101 away from the front cover 102, the front cover 102 is provided with a light outlet hole, and the light of the light source module is emitted from the light outlet hole. The base 200, the intermediate connector 101 and the front cover 102 of this example are all made of insulating materials.

[0037] The light source module includes a light source 106, a first electrode 107 and a second electrode 105 respectively connected to the positive and negative poles of the conductive pin 500, and the light source module is provided with a planar light emitting surface 1061 corresponding to the light emitting hole of the front cover 102, and a filter layer is provided on the planar light emitting surface 1061. The light source 106 is filled with an inert gas for luminescence, and the first electrode 107 and the second electrode 105 excite the inert gas to emit ultraviolet rays, and the light is emitted through the planar light emitting surface 1061.

[0038] Through the structure, single-side light emission is achieved, and the light-emitting surface is flat. It is easy to realize vacuum mounting or coating of the filter layer to obtain an optional effective wavelength without noise. The filter layer in this example is a filter. Of course, it can also be replaced by a coating. The solid line is disinfected by ultraviolet irradiation of a specific wavelength. The coating method greatly reduces the production cost. Compared with the use of dedicated filters, the production cost is further reduced, which can make ultraviolet lamps more popular and allow more people to use them.

[0039] Preferably, the intermediate connector 101 and the front cover 102 are also detachably connected by threads. By setting the ultraviolet lamp body 100 as the intermediate connector 101 and the front cover 102, and detachably connecting the intermediate connector 101 and the front cover 102 by threads, the error of the light source can be eliminated by the height of the thread rotation, and the poor contact between the second electrode and the heat dissipation conductive member, and between the heat dissipation conductive member and the conductive ejector pin in the ultraviolet lamp body caused by the size error of the light source can be avoided. Moreover, without adopting other fixed structures, the first electrode, the second electrode and other conductive elements can be firmly pressed in the intermediate connector, and the assembly is simpler and more convenient. Of course, this example can also be connected by a detachable connection structure such as a snap-on connection.

[0040] The light source 106 in this example is in the shape of a round cake, including an arc surface arranged on the side of the light source 106, and a first plane and a plane light-emitting surface 1061 respectively arranged on both sides of the arc surface. The first electrode 107 matches the size of the arc surface and is wrapped around the outer wall of the arc surface. The second electrode 105 covers the first plane.

[0041] Of course, the shape of the light source 106 in this example is not limited to a round cake shape, and can be other shapes such as a square and an ellipse. The shape of the side opposite to the planar light emitting surface 1061 is not limited to a plane, and can also be set to an arc surface, a conical surface, etc.

[0042] A heat dissipation conductive member 104 is also provided on the side of the second electrode 105 away from the light source 106, and a pressing sheet 1051 is also provided on both sides of the side of the second electrode 105 close to the heat dissipation conductive member 104. The heat dissipation conductive member 104 is inserted under the pressing sheet 1051, so as to achieve close contact between the second electrode 105 and the heat dissipation conductive member 104, and increase the conductive stability of the second electrode 105 while dissipating heat. In this example, a conductive connecting member 103 connected to the first electrode 107 is also provided at the bottom of the intermediate connecting member 101. Two conductive members extend from the conductive connecting member 103 close to the first electrode 107 to achieve electrical connection with the first electrode 107.

[0043] Preferably, in this example, the first electrode 107 and the second electrode 105 are both provided with an ultraviolet reflection layer on one side close to the light source 106. Preferably, the ultraviolet reflection layer adopts a mirror aluminum structure, which has a better reflection effect. In this example, except for the plane light emitting surface, the ultraviolet reflection layers on other surfaces of the ultraviolet lamp body can emit all the reflected light through the plane light emitting surface, further increasing the irradiation intensity and improving the sterilization and disinfection effect.

[0044] The creative improvements in this example can be applied to the current mainstream human-machine coexistence technology. The 222nm ultraviolet lamp is a new ultraviolet technology that uses krypton chloride inert gas to emit light. It also has a feature that after filtering out the 230nm ultraviolet clutter, it can directly irradiate the human body without penetrating the cornea and skin, and can achieve human-machine coexistence for a certain period of time (there is an upper limit to the total energy of 222nm ultraviolet rays received by the human body every day). This is not available in other ultraviolet lamps. Using 222nm within the currently allowed daily exposure safety threshold can effectively disinfect the surrounding environment while taking into account human safety.

[0045] The utility model can filter out the clutter that is directly harmful to the human body surface by setting a suitable filter layer, thereby achieving true 222 nanometer wave sterilization, which is safer. The utility model has the advantages of simple structure and low cost, making the ultraviolet lamp module of the utility model more practical and popular.

[0046] Compared with the prior art, the beneficial effect of the utility model is that by setting the ultraviolet lamp module as a detachable base and ultraviolet lamp body, when the lamp body cannot be used normally, only the ultraviolet lamp body needs to be replaced, and no additional wiring operations are required. On the one hand, lossless connection and separation can be quickly performed to achieve convenient and fast replacement of light sources. On the other hand, compared with scrapping the entire machine, the base part can be reused, which is more energy-saving and emission-reducing. The user only needs to purchase the ultraviolet lamp body for replacement, which effectively reduces the user's use cost.

[0047] The specific implementation methods described above are preferred implementation methods of the present utility model, and are not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation methods. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
