Description

Portable UV sterilizer

The present invention relates to a portable ultraviolet sterilizer, and more particularly, to a portable ultraviolet sterilizer using an ultraviolet light emitting diode (UV LED, Ultra Violet Light Emitting Diode).

In general, ultraviolet (Ultraviolet, UV) has a large bactericidal action within a wavelength range of approximately 150 to 380 nm or 250 to 260 nm.

The sterilizer using ultraviolet rays is a device that turns on an ultraviolet lamp to destroy the epidermis and DNA of bacteria by using the wavelength emitted from the ultraviolet rays, and is largely divided into a fixed sterilizer and a portable sterilizer.

Fixed UV sterilizers are used in dish sterilizers, drinking water sterilizers, refrigerators, washing machines, vacuum cleaners, etc. equipped with UV lamps, but this has the disadvantage of being able to sterilize only in a limited space.

A portable UV sterilizer that overcomes these shortcomings is a portable UV sterilizer, which is easy to move and can be sterilized anywhere as long as there is a power supply. It has the advantage of being able to sterilize various types of bacteria, so it is widely used in homes and businesses.

On the other hand, the conventional portable UV sterilizer has a great advantage that it can be easily moved to a place requiring sterilization because it is portable. In particular, there is a problem in that children must not use it, and always keep it out of reach of children.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. In describing the present invention, in order to facilitate the overall understanding, the same reference numerals are used for the same components in the drawings, and duplicate descriptions of the same components are omitted.

1 to 3 are views for explaining the configuration of a portable UV sterilizer according to an embodiment of the present invention, and FIG. 4 is a view showing the release of the coupling between the main body part and the sub-body part of the portable UV sterilizer according to the embodiment of the present invention. It is a drawing that shows

The portable ultraviolet sterilizer according to an embodiment of the present invention includes a main body part 10 , a sub-body part 20 , and one or more light emitting module parts 30 , 40 , 50 .

The main body part 10 may be configured in a form in which a PCB substrate (not shown) and a rechargeable battery can be embedded.

A connection part 11 for electrical connection with the light emitting module parts 30 , 40 , 50 is installed on a first surface (eg, an upper surface) of the main body part 10 . For example, the connection part 11 may be configured as a magnet type pogo pin.

In addition, a bracket 12 of a predetermined height is formed to protrude around the connection part 11 .

The bracket 12 reinforces the coupling force (fixing force) between the light emitting module part and the connection part 11 of any one of the plurality of light emitting module parts 30 , 40 , 50 . For example, the bracket 12 may be configured in such a way that any one of the light emitting module units 30, 40, and 50 can be fitted or removed. For example, the bracket 12 may be formed in a form that can further reinforce the force compared to a cylindrical shape.

That is, when any one of the plurality of light emitting module parts 30, 40, and 50 is coupled to the connection part 11, one end of the corresponding light emitting module part passes through the bracket 12 to the connection part 11. are combined At this time, since the inner surface of the bracket 12 is closely or almost in close contact with the outer surface of one end of the light-emitting module part, the bracket 12 reinforces the bonding force (fixing force) between the light-emitting module part and the connection part 11 . do.

For example, if it is assumed that there is no bracket 12 and any one of the plurality of light emitting module parts 30, 40, and 50 is coupled to each other, the By this, the light emitting module part may be separated from the connection part 11 or may be bent while being coupled to the connection part 11 .

However, when the bracket 12 is formed to protrude to a predetermined height around the connection part 11, even if an unwanted external force is applied, the light emitting module part is separated from the connection part 11 or bent while combined with the connection part 11. can

In addition, as the bracket 12 is formed to protrude around the connection part 11 , one end of the light emission module part among the plurality of light emission module parts 30 , 40 , 50 is more easily guided to the connection part 11 . and can be combined. That is, it can be seen that the bracket 12 serves as a guide.

In addition, the bracket 12 reinforces the coupling force (fixing force) between the connection part 11 and the finishing part to be described later.

On the other hand, on the first surface (eg, upper surface) of the main body portion 10, the charging terminal portion 14 is formed to be spaced apart from the connection portion (11). For example, the charging terminal unit 14 may be configured as a USB charging port. The rechargeable battery inside the main body unit 10 may be charged with power input through the charging terminal unit 14 .

A light emitting device 18 capable of emitting ultraviolet light is fixedly installed on the second surface (eg, front) of the main body 10 . For example, the light emitting device 18 may be composed of a UV LED.

Here, the light emitting device 18 may be installed to be embedded in a predetermined depth rather than protruding from the second surface of the main body 10 , and may be electrically connected to a PCB substrate (not shown).

Accordingly, the ultraviolet light emitted from the light emitting element 18 is irradiated based on the emission angle of the emission angle forming unit 16 formed around the light emitting element 18 . Here, the emission angle of the emission angle forming unit 16 may be fixed to the emission angle set in the product production step.

For example, the emission angle forming unit 16 may be formed around the light emission surface of the light emitting device 18, and may be formed in a shape that is obliquely spread outwardly from the light emission surface.

In addition, a power button 19 is installed on the third surface of the main body 10 (eg, any one of both sides). For example, the power button 19 may be driven in a sliding manner. The power button 19 will be electrically connected to a PCB board (not shown).

On the other hand, the sub-body portion 20 is preferably formed to have a shorter length than the length of the main body portion (10). That is, the sub-body portion 20 is preferably formed to have a length that does not block the ultraviolet light emitted from the light emitting device 18 of the main body portion 10 .

One or more accommodating portions 22a, 22b, and 22c are formed in the sub-body portion 20 in the longitudinal direction.

The light emitting module units 30, 40, and 50 may be accommodated in the accommodating units 22a, 22b, and 22c.

Of course, in FIGS. 1 to 4 , the first light emitting module unit 30 is accommodated in the accommodating part 22a, the second light emitting module part 40 is accommodated in the accommodating part 22b, and the third light emitting module part 30 is accommodated in the accommodating part 22b. Although the module part 50 is illustrated as being accommodated in the accommodating part 22c, the present invention is not limited thereto. That is, the light emitting module units 30 , 40 , and 50 may be accommodated in any of the three accommodating units 22a , 22b and 22c without a predetermined position.

Here, the light emitting module units 30 , 40 , and 50 may each irradiate ultraviolet light.

The light emitting module units 30 , 40 , and 50 may be formed to have the same size and the same shape as each other.

The light emitting module units 30 , 40 , and 50 may be formed in a bar shape of a predetermined length, and the light emitting module units 30 , 40 , 50 are to be connected to the connection unit 11 through the bracket 12 . formed in a form that can be For example, the light emitting module parts 30 , 40 , and 50 are preferably formed in a shape that can receive a force better than that of a cylindrical shape.

Since the light emitting module units 30, 40, and 50 are accommodated in the accommodating parts 22a, 22b, 22c and can be easily taken out later, a part of the light emitting module parts 30, 40, 50 is accommodated in the accommodating part ( 22a, 22b, 22c) is preferably accommodated so as to be exposed to the outside. In particular, even when the light emitting module parts 30 , 40 , 50 are accommodated in the accommodating parts 22a , 22b , 22c and the main body part 10 and the sub-body part 20 are attached to each other, the main body part 10 ), it is preferable not to hit the ultraviolet light emitted from the light emitting device 18 .

In addition, the light emitting module units 30 , 40 , 50 are formed to be detachable from each other. A more detailed description of the light emitting module units 30 , 40 , and 50 will be described later.

On the other hand, although not shown in the drawings, a fixing member (eg, a magnet) that can easily fix the light emitting module parts 30, 40, 50 accommodated inside the accommodating parts 22a, 22b, 22c may be installed. have. Because the ultraviolet sterilizer of the present invention is a portable sterilizer, if the light emitting module parts 30, 40, 50 are arbitrarily removed from the receiving parts 22a, 22b, 22c while carrying, a problem may occur during subsequent use. Accordingly, when the above-described fixing member (eg, a magnet) is installed inside the accommodating parts 22a, 22b, 22c, the light emitting module parts 30, 40, 50 accommodated in the accommodating parts 22a, 22b, 22c. ) can be prevented from falling out unintentionally.

For example, when the first light emitting module unit 30 is accommodated in the accommodating part 22a, a fixing member (eg, a magnet) (not shown) installed in the accommodating part 22a is the first light emitting module part. It may be in contact with one end of the 30 or may be opposed at a predetermined distance. Accordingly, the first light emitting module unit 30 accommodated in the accommodating part 22a can be maintained in the accommodating state without being easily removed by the magnetic force of the magnet. Of course, when the user pulls the first light emitting module part 30 with a force greater than or equal to the magnetic force of the magnet, the first light emitting module part 30 can be pulled out from the receiving part 22a. The other light emitting module units 40 and 50 are also the same.

One side of the light emitting module part 30, 40, 50 that is in contact with a fixing member (eg, a magnet) installed at one end of the receiving part 22a or is opposed at a predetermined distance is shielded for electrical protection from the magnetic force of the magnet It is preferably treated.

1 to 4, the above-described fixing member (eg, magnet) is not shown, but those who are engaged in the same industry will be able to fully understand the above description.

In particular, the main body portion 10 and the sub-body portion 20 can be separated and combined as shown in FIGS. 1 to 4 .

For example, the main body portion 10 is formed of a metal material, and by installing a detachable member (eg, a magnet) on one surface of the sub-body portion 20 (that is, the surface in contact with the main body portion 10). , the main body portion 10 and the sub-body portion 20 are detachable from each other.

Here, the detachable member is formed of a magnet in the form of a thin flat plate and may be entirely installed on one surface of the sub-body part 20 (ie, a surface in contact with the main body part 10 ).

On the other hand, the detachable member is formed of a magnet in the form of a thin band and may be installed on both sides of one surface of the sub-body part 20 (ie, the surface in contact with the main body part 10) in the longitudinal direction.

The installation position of the above-described detachable member (eg, magnet) may be changed. That is, a detachable member (eg, a magnet) may be installed on the main body portion 10 , and the sub-body portion 20 may be formed of a metal material.

Of course, in the above description, the main body part 10 and the sub-body part 20 are detached from each other by taking the magnet as an example, but the main body part 10 and the sub-body part 20 can be detached from each other other than the magnet. Any member or structure that is present may be employed.

In the embodiment of the present invention, if a magnet is used as a detachable member, the main body 10 and the sub-body 20 can be easily detached from each other without the need to additionally configure a special structure, so a magnet is adopted as a detachable member. did.

1 to 4, the above-described detachable member (eg, a magnet) is not shown, but those who are engaged in the same industry will be able to fully understand the above description.

FIG. 5 is a view showing a case in which a plurality of light emitting module units shown in FIG. 1 are coupled to a main body.

In order to operate the portable UV sterilizer according to the embodiment of the present invention, as shown in FIG. 5 , the light emitting module parts 30 , 40 , 50 accommodated in the sub-body part 20 are connected to the connection part of the main body part 10 . (11) should be electrically connected. Here, one or more light emitting devices 30a, 40a, 50a capable of emitting ultraviolet light are fixedly installed in the light emitting module units 30 , 40 and 50 . That is, one or more light emitting devices 30a are installed to be spaced apart from each other in the first light emitting module unit 30, and one or more light emitting devices 40a are installed to be spaced apart from each other in the second light emitting module unit 40, One or more light emitting devices 50a are installed in the third light emitting module unit 50 to be spaced apart from each other. For example, the above-described light emitting devices 30a, 40a, and 50a may be configured as UV LEDs. In addition, the emission angles of the above-described light emitting devices 30a, 40a, and 50a may be equal to each other.

In order to electrically connect the light emitting module parts 30 , 40 , 50 to the connection part 11 of the main body part 10 , the user first needs to use each of the light emitting module parts accommodated in the sub body part 20 ( 30, 40, 50 are taken out from the accommodating parts 22a, 22b, 22c.

Then, the user electrically connects any one of the light emitting module parts 30, 40, and 50 (eg, the first light emitting module part 30) to the connection part 11 of the main body part 10, Next, the second light emitting module unit 40 is electrically connected to the first light emitting module unit 30 , and then the third light emitting module unit 50 is electrically connected to the second light emitting module unit 40 . make it

Then, the closing part 60 is fitted at the end of the third light emitting module part 50 . Here, the light emitting device 60a capable of emitting ultraviolet light is fixedly installed on the closing part 60 . For example, the emission angle of the light emitting device 60a may be different from that of the other light emitting devices 30a, 40a, and 50a.

In this way, as shown in FIG. 5 , the light emitting module parts 30 , 40 , 50 and the closing part 60 are electrically connected to the connection part 11 of the main body part 10 in a line with each other.

In FIG. 5, the first light emitting module unit 30, the second light emitting module unit 40, and the third light emitting module unit 50 are connected in this order, but the connection order may be different.

After that, the user operates the power button 19 to turn on the power, and then holds the main body part 10 and the sub-body part 20 coupled to each other by hand, and the main body part 10 and the light emitting module The light emitting devices 18 , 30a , 40a , 50a , 60a of the parts 30 , 40 , 50 and the closing part 60 are directed to the sterilization target.

Accordingly, the object to be sterilized is sterilized by the ultraviolet light emitted from the light emitting elements 18, 30a, 40a, 50a, and 60a.

In FIG. 5 , the light emitting module parts 30 , 40 , 50 and the closing part 60 are connected so that the light emitting devices 30a , 40a , 50a , and 60a all face in the same direction, but they may be connected differently. For example, you may connect them in a zigzag manner. That is, at least one of the light emitting devices 30a, 40a, 50a, and 60a may be connected to the corresponding light emitting module unit and the finishing unit so as to face the other light emitting device in the opposite direction.

On the other hand, in FIG. 5, the light emitting devices 30a, 40a, 50a, and 60a are formed on only one surface of the light emitting module parts 30, 40, 50 and the finishing part 60, and if necessary, both sides (that is, , one side and the side opposite to the one side) may be formed on both sides.

In addition, although FIG. 5 shows that three light emitting module units are connected in series, less than three or four or more light emitting module units may be connected in series if necessary.

This time, the configuration of any one of the plurality of light emitting module units 30 , 40 , 50 will be described in more detail. 6 is an enlarged view of the third light emitting module unit shown in FIG. 5 , FIG. 7 is a cross-sectional view of the third light emitting module unit shown in FIG. 6 , and FIG. 8 is the third light emitting module unit shown in FIG. 5 . It is a drawing for explaining the combination of the and the finishing part.

6 and 7, the third light-emitting module unit 50 is enlarged, but the first light-emitting module unit 30 and the second light-emitting module unit 40 are also shown in the third light-emitting module unit 50 ) is the same as the configuration of

A connection part 54 for electrical connection with the closing part 60 is installed on one side of the third light emitting module part 50 . For example, the connection part 54 may be configured as a magnet type pogo pin. In other words, the connection part 54 may be installed inside the third light emitting module part 50 , and may be installed inside the third light emitting module part 50 to be spaced apart from one end of one side by a predetermined distance.

Accordingly, the space between the connection part 54 and the end of one side of the third light emitting module part 50 may be the fitting part 52 into which one side of the closing part 60 is fitted. Here, it can be seen that the fitting part 52 performs the same function as the above-described bracket 12 . Referring to FIG. 8 , a connector 62 of a magnet type capable of being coupled to the connection part 54 is formed on one side of the closing part 60 , so the connector 62 of the closing part 60 has the fitting part 52 . It may be coupled to the connection part 54 of the third light emitting module part 50 through the.

Here, the closing part 60 may prevent foreign substances such as dust from entering the fitting part 52 of the third light emitting module part 50 .

In the above, it has been described that one side of the closing part 60 is fitted to the fitting part 52 , but the connector 62 of the closing part 60 is actually directly connected to the connection part 11 of the main body part 10 . Also, the connector 62 of the closing part 60 is inserted into the fitting portion of the first to third light emitting module parts 30, 40, 50 and the first to third light emitting module parts 30, 40, 50) may be connected. That is, if it is assumed that the light emitting module part shown in FIG. 6 is the first light emitting module part 30 , the closing part 60 is inserted into the fitting part of the first light emitting module part 30 to be the first light emitting module part. It may be connected to the connection part of the part 30 . As another example, if it is assumed that the light emitting module part shown in FIG. 6 is the second light emitting module part 40 , the closing part 60 is inserted into the fitting part of the second light emitting module part 40 to allow the second light It may be connected to the connection part of the emission module part 40 .

On the other hand, in FIGS. 6 and 7 , on the other side of the third light emitting module part 50 , the connection part formed inside the other light emitting module part 30 or 40 or the connection part 11 of the main body part 10 and A connector 56 that can be electrically connected is installed. For example, when the third light emitting module unit 50 is continuously connected after the first light emitting module unit 30 and the second light emitting module unit 40 are connected in order, the third light emitting module unit 50 is continuously connected. The connector 56 of the module part 50 will be electrically connected to the connection part of the second light emitting module part 40 .

Here, the connector 56 may be configured as a magnet-type connector capable of engaging and disengaging with a connection part composed of a magnet-type pogo pin.

9 and 10 are diagrams for explaining the configuration of a portable UV sterilizer according to another embodiment of the present invention, and FIG. 11 is a coupling between the main body part and the sub-body part of the portable UV sterilizer according to another embodiment of the present invention. A drawing showing the release.

The portable ultraviolet sterilizer according to another embodiment of the present invention is compared to the portable ultraviolet sterilizer according to the embodiment of the present invention described above ( FIGS. 1 to 8 ), the point that there is no bracket 12 and a lid 70 is added. It differs only in that it is provided with Accordingly, among the components of the portable UV sterilizer according to another embodiment of the present invention, the same reference numerals are given to the same components as those of the portable UV sterilizer according to the embodiment of the present invention.

The main body part 10 and the sub-body part 20 of the portable ultraviolet sterilizer according to another embodiment of the present invention can be separated and combined with each other as in the portable ultraviolet sterilizer according to the embodiment of the present invention described above.

When the bracket 12 is not formed as shown in FIG. 9 , the connection part 11 moves from the first surface (eg, upper surface) of the main body 10 to the inside of the main body 10 as shown in FIG. 10 . It is formed to be buried by a predetermined value, and it is preferable that one side (eg, the upper side) is opened. Here, the light emitting module unit 30 , 40 , or any one of 50 ) or a finishing unit to be described later will be connected to the connection unit 11 through the open side (eg, upward).

In this way, instead of forming the bracket 12, if the connection part 11 is formed to be embedded in the inside of the main body part 10 by a predetermined value, as in the portable UV sterilizer according to the embodiment of the present invention described above, a plurality of The coupling force (fixing force) between the light emitting module units 30 , 40 , and 50 and the connection unit 11 may be reinforced. In addition, one end of the light emitting module parts 30, 40, 50 can be more easily guided to the connection part 11, and the coupling force (fixing force) between the connection part 11 and the finishing part to be described later can be reinforced. .

On the other hand, the sub-body portion 20 is provided with a lid (70). The lid 70 may cover the light emitting module parts 30 , 40 , and 50 accommodated in the accommodating parts 22a , 22b , 22c of the sub-body part 20 . The lid 70 not only blocks the inflow of foreign substances into the accommodating parts 22a, 22b, 22c or the light emitting module parts 30, 40, 50 accommodated in the accommodating parts 22a, 22b, 22c, but also the accommodating part ( It is possible to block children's contact with the light emitting module units 30, 40 and 50 accommodated in 22a, 22b, and 22c.

In addition, the lid 70 may have a light-passing hole 70a (refer to FIG. 11 ) formed therein. The light passage hole 70a has a size sufficient to allow ultraviolet light emitted from the light emitting device 18 of the main body 10 to be irradiated without blocking. In other words, since the light emitting device 18 capable of emitting ultraviolet light is installed on the upper portion of the second surface (eg, the front side) of the main body portion 10, if there is no light passage hole 70a, the lid 70 ) will block the ultraviolet light emitted from the light emitting device 18 . Therefore, in order to prevent blocking of the ultraviolet light emitted from the light emitting device 18, a light passage hole (70a) is formed in the lid (70).

In the portable UV sterilizer according to another embodiment of the present invention, the lid 70 is installed to the sub-body portion 20 in a detachable structure. Of course, if necessary, the lid 70 may be installed on one side of the sub-body portion 20 via a hinge.

12 is a view showing a case in which a plurality of light emitting module units are coupled to a main body in another embodiment of the present invention.

In order to operate the portable UV sterilizer according to another embodiment of the present invention, the light emitting module parts 30 , 40 , 50 accommodated in the sub body part 20 are connected to the connection part 11 of the main body part 10 . electrically connect.
