Description

UV Sterilizer {UV Sterilizer}

This is about a UV sterilizer that allows natural device movement.

In general, a UV (ultraviolet ray) sterilizer refers to a device designed to sterilize bacteria on the object to be sterilized by irradiating UV (ultraviolet rays) to the object to be sterilized.

Until recently, most of these UV sterilizers were intended to sterilize objects of a specific type, such as sanitary instruments or medical instruments.

This UV sterilizer has a relatively simple structure, including a housing to accommodate sanitary equipment, etc., a UV lamp provided on one side of the housing to irradiate ultraviolet rays into the housing space, and a stabilizer to convert external input power into driving power for the UV lamp. .

Meanwhile, the sterilization effect of UV is becoming more widely known, the non-face-to-face culture is rapidly spreading due to the recent outbreak of the coronavirus, and the social atmosphere that emphasizes hygiene above all else is widespread. In addition to sanitary and medical devices, , demand for using UV sterilizers is rapidly increasing in general homes and restaurants. In particular, UV sterilizers are becoming an essential item in restaurants where many customers come and eat every day.

However, most of the conventional UV sterilizers involved inserting the device into a large sterilizer with a UV lamp and waiting for a certain period of time. Therefore, no matter how large the sterilizer is, it can sterilize large quantities of spoons, water cups, etc., but it cannot be used on tables or chairs. It was impossible to sterilize the back. Therefore, restaurants are still sterilizing cutlery and water cups with UV sterilizers, but tables and chairs are not sterilized separately and are managed by wiping them with dishcloths.

However, viruses such as coronavirus cannot be killed by wiping them with a dishcloth, and in the current situation where vaccines and treatments are not appropriate as various mutant viruses continue to emerge, there is a method that can completely sterilize tables and chairs with UV. Demand for UV sterilizers is growing explosively.

Accordingly, the present inventors accurately understood this demand and, after experiencing numerous trials and errors, came to complete the present invention.
Meanwhile, prior art related to the present invention includes Registered Utility Model Publication No. 20-0310601, Public Patent Publication No. 10-2015-0115171, Registered Patent Publication No. 10-1707093, and Public Utility Model Publication No. 20-2019-0000989. Ho, etc.

One embodiment can provide a UV sterilizer that can naturally adjust the length even while the device is being moved, allowing very easy sterilization of chins or uneven surfaces. Furthermore, most UV lamps used in UV sterilizers are UV-C lamps. UV-C lamps decompose oxygen molecules in the air, so they can generate ozone, which is harmful to the human body. If ozone is inhaled, it can damage the laryngeal mucosa, bronchi, It can cause damage to lung cells and reduce respiratory function. Therefore, if the UV rays emitted from the UV sterilizer come in direct contact with the human skin or are seen with the naked eye, it may have a harmful effect on the human body. According to one embodiment, the UV sterilizer is completely prevented from escaping out of the sterilizer even while it is operating. Since it is possible to block UV sterilization, you can safely perform UV sterilization.

Hereinafter, implementation examples will be described in detail so that those skilled in the art can easily implement them. However, it may be implemented in various different forms and is not limited to the implementation example described here.

In the drawing, the thickness is enlarged to clearly express various layers and regions. Throughout the specification, similar parts are given the same reference numerals. When a part of a layer, membrane, region, plate, etc. is said to be “on” another part, this includes not only cases where it is “directly above” the other part, but also cases where there is another part in between. Conversely, when a part is said to be “right on top” of another part, it means that there is no other part in between.

The UV sterilizer (1) according to one embodiment includes a polygonal seedbed portion (10) to which a UV lamp (40) is attached; A connecting portion (20) coupled to an edge constituting the polygonal seedbed portion; and a support part 30 coupled to the connection part, wherein the support part includes a first module 21, a second module 22, and a third module 23, and the first module is connected to the connection part. Located between the second modules, the second module is located between the first module and the third module, and the first module, second module, and third module each independently include a coupling portion 61; , the second module and the third module each independently include length-adjusting protrusions and convexities, and the first module and the second module have a portion of one side open and have an empty space inside.

Conventionally, in order to perform UV sterilization, small objects were put directly into a UV sterilizer and then UV sterilized. However, in this case, there was a problem that UV sterilization of large objects was not easy.

Accordingly, devices that allow a person to carry around a UV sterilizer and UV sterilize items have been introduced, but all of these sterilizers have no choice but to see UV with the human eye, or no matter how careful one is, the UV emitted during UV sterilization can be harmful to people. Since it has no choice but to come into direct contact with the skin, it is becoming another problem.

However, the UV sterilizer 1 according to one embodiment includes a seedbed portion 10, a connection portion 20, and a support portion 30, and the support portion includes the first module 21, the second module 22, and the second module. It includes three modules (23), wherein the second module and the third module each include length-adjusting protrusions, the first module and the second module have a portion of one side opened and are hollow inside, and the first module and the third module each include length-adjusting irregularities. 1 The second module can be easily inserted into the module, and the third module can be easily inserted into the second module, so that UV does not leak out even if there are protrusions or uneven surfaces, and natural and easy The UV sterilizer can be moved (that is, without removing the UV sterilizer from the uneven surface, the UV sterilizer can be kept in contact with the uneven surface very easily, sliding over a large area including the uneven surface. Since it can be moved), all of the above-mentioned problems can be solved. Since the UV sterilizer does not fall off the surface while being moved, there is no need to worry about UV leaking from the UV sterilizer.

For example, when the connecting portion is combined with the edge constituting the polygonal seed plate portion, the internal angle may be 90° or more and less than 180°, for example, 90° to 150°, for example, 90° to 120°. there is. However, if the internal angle is 90° or more and less than 180°, the specific angle value is not limited. The wider the area to be UV sterilized, the larger the internal angle is, the more advantageous, and the narrower the area to be sterilized, the internal angle is. The smaller it is, the more advantageous it can be.

For example, the first module may have a different shape from the second module and the third module. At this time, the second module may have the same shape as the third module or may have a different shape.

For example, the length adjustment irregularities of the second module and the length adjustment irregularities of the third module each independently include concave portions 41, and the depth d of the concave portions of the length adjustment irregularities of the second module is the second module. 3 The length of the module can be deeper than the depth (d) of the concave part of the unevenness. The deeper the depth of the concave portion of the length adjustment unevenness, the more force it may take to insert another module into the empty module. Therefore, if the surface to be UV sterilized is not severely uneven, UV sterilization can be completely performed without applying much force. If the surface to be UV sterilized is extremely uneven, more force must be applied to connect the second module. By allowing the third module to be inserted into the first module and the second module, respectively, UV sterilization can be performed perfectly. In other words, by controlling the size difference between the depth (d) of the concave portion of the length-adjustable concave-convex portion of the second module and the depth (d) of the concave portion of the length-adjustable concave-convex portion of the third module as described above, an easier and more natural UV sterilizer can be produced. Movement can be implemented, which ultimately allows for more perfect UV sterilization while preventing UV leakage from all surfaces to be UV sterilized, regardless of the unevenness of the surface. (If the depth (d) of the concave portion of the length-adjusting unevenness of the second module is shallower than the depth (d) of the concave portion of the length-adjusting unevenness of the third module, UV Even when sterilizing, excessive force must be applied, and if the depth (d) of the concave portion of the length-adjusting concave-convex of the second module is the same as the depth (d) of the concave portion of the length-adjusting concave-convex of the third module, the product 2 A phenomenon may occur where the 2nd module and the 3rd module are inserted into the 1st module and the 2nd module, respectively, or the 2nd module and the 3rd module are not inserted into the 1st module and the 2nd module, respectively, even though a lot of force is applied. This may be undesirable.)

For example, the second module and the third module may each independently include a full insertion prevention portion 51 at the bottom. Since the second module and the third module are not completely inserted into the first module and the second module, respectively, through the complete insertion prevention part, the length adjustment of the support part can be well controlled according to the unevenness of the surface to be UV sterilized. there is. That is, in addition to the large difference between the depth (d) of the concave portion of the length-adjusting unevenness of the second module and the depth (d) of the concave portion of the length-adjusting unevenness of the third module, the depth (d) of the concave portion of the length-adjusting unevenness of the second module is at the bottom of each of the second module and the third module. By including a complete insertion prevention part, UV sterilization can be performed more completely while preventing UV leakage from all surfaces to be UV sterilized, regardless of the unevenness of the surface. For example, if there is no complete insertion prevention part at the bottom of each of the second and third modules, when a force exceeding a certain amount is applied, both the second and third modules are completely inserted into the first and second modules in an instant. While moving the UV sterilizer, the UV sterilizer may slightly lift or turn over on the surface, which may be undesirable because there is a risk that the UV sterilizer may be seen directly with the human eye or the UV rays may come in direct contact with the human skin.

For example, the third module may include a wheel 60 at the bottom.

Since the third module includes wheels at the bottom, the UV sterilizer according to one embodiment can be moved more easily.

Meanwhile, when the third module includes a wheel at the bottom, the third module may further include a cover 70 surrounding the wheel. The wheel causes a gap between the surface to be UV sterilized and the bottom of the third module, causing the UV sterilizer to fall on the surface to be UV sterilized, causing UV to leak out of the sterilizer. The cover protects the wheel. At the same time, the UV can be prevented from leaking out of the sterilizer.

For example, the second module may be composed of two or more sub-modules. That is, the support unit may be composed of one first module, one third module, and two or more second modules.

The sub-module may include, for example, a 2-1 module and a 2-2 module, but is not necessarily limited thereto and may further include a 2-3 module, a 2-4 module, etc.

Assuming that the second module includes a 2-1 module and a 2-2 module, the 2-1 module may be located between the first module and the 2-2 module.

At this time, the 2-1 module and the 2-2 module each independently include length adjustment irregularities, and the length adjustment irregularities of the 2-1 module and the length adjustment irregularities of the 2-2 module are each independently It includes a concave portion, and the depth of the concave portion of the length adjustment convexity and protrusion of the 2-1 module may be deeper than the depth of the concave portion of the length adjustment convexity and convexity of the 2-2 module, and the beneficial effects thereof are the same as described above. do.

In addition, the 2-1 module and the 2-2 module may each independently include a complete insertion prevention portion at the bottom, and the beneficial effects thereof are the same as those described above.

For example, the first module and the second module may each independently include circular finishing parts facing each other, and a space between the facing circular finishing parts may be open.

The second module can be inserted into the first module through the opening, and the third module can be inserted into the second module.

For example, the UV lamp may be attached to the bottom of the seedbed portion, and the connection portion and support portion may each independently surround the UV lamp. The UV sterilizer according to one embodiment should have this shape so that the UV sterilizer does not easily turn over during movement and can sterilize as large an area as possible with a single sterilization.

For example, the connection part may include a reflector 45 on its inner surface.

For example, the first module may include a reflector 45 on its inner surface.

For example, the second module may include a reflector 45 on its inner surface.

For example, the third module may include a reflector 45 on its inner surface.

For example, the second module may be composed of two or more sub-modules, and the two or more sub-modules may all include reflectors 45 on their inner surfaces.

For example, the reflector may include a metal oxide coating layer on its surface.

For example, the metal oxide may be magnesium oxide.

For example, the metal oxide coating layer may have a thickness of 0.05㎛ to 0.2㎛.

When the surface of the reflector is coated with magnesium oxide, the sterilization effect can be further improved because the reflectivity for UV is high. At this time, the magnesium oxide may be formed on the surface of the reflector to a thickness of 0.05 ㎛ to 0.2 ㎛. The method of forming the magnesium oxide coating layer may use a vacuum deposition process, but is not necessarily limited thereto. If the magnesium oxide is coated on the surface of the reflector with a thickness of less than 0.05㎛, the reflection effect is reduced and the UV reflection range is narrowed, which may lower the sterilizing power by the UV lamp. If the magnesium oxide is coated with a thickness exceeding 0.2㎛, the thickness increases. The increase in reflectance may become insignificant.

For example, the seedbed unit may include two or more UV lamps, but is not necessarily limited thereto.

For example, the seedling unit may further include a handle at the top, and the shape of the handle is not particularly limited.

For example, the UV lamp may be a UV-C lamp. In this case, the sterilization effect against viruses, etc. may be more excellent.

Although the preferred embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements can be made by those skilled in the art using the basic concept of the present invention as defined in the following claims.
