Description

{Portable sterilizing apparatus for straw}

The present invention relates to a portable straw sterilizing device, and more specifically, to a portable straw sterilizing device having a simplified structure and capable of separately performing washing and sterilizing operations on straws.

Generally, when drinking beverages from cups or cans, you can drink them directly from the cup or can, but if necessary, you can use a straw to drink from the cup or can. These straws are made of rubber, silicone, plastic, stainless steel, etc., and are hollow inside. They can be divided into straight straws that are long and straight and crimped straws that can be bent at the top.

Straws are exposed to the air, so dust and other foreign substances can stick to their surfaces. In addition, the inner surface, which provides a hollow drinking passage after use, is not sufficiently dry, so bacteria can easily grow, so washing and sterilization are essential.

Meanwhile, various types of cleaning and sterilizing devices are being used to clean and sterilize toothbrushes, baby products, etc.

For example, cleaning devices for cleaning toothbrushes, baby products, etc. are disclosed in Korean Patent Publication No. 10-2012-0061304 (Toothbrush cleaning device and oral condition checking method using the same) (published on June 13, 2012), Korean Utility Model Publication No. 20-1999-0033362 (Infant bottle and nipple cleaning and sterilizing device) (published on August 5, 1999), etc.

In addition, sterilizing devices for sterilizing toothbrushes, baby products, etc. are disclosed in Domestic Utility Model Publication No. 20-0455283 (Portable Toothbrush Sterilizer) (announced on September 1, 2011), Domestic Patent Publication No. 10-2093993 (Multifunctional Portable Toothbrush Sterilizer) (announced on March 26, 2020), Domestic Patent Publication No. 10-1684297 (Children's and Infants' Equipment Sterilizer) (announced on December 8, 2016), etc.

However, conventional washing devices and sterilizing devices have a complex structure, and since a washing device for washing and a sterilizing device for sterilizing must be separately provided, there is a problem that the cost and time for washing and sterilizing operations are high.

Moreover, in the case of straws, unlike general toothbrushes and baby products, there was a problem in that the inner surface that provides the drinking passage was not exposed to the outside, making it difficult to wash and sterilize.

Therefore, a portable straw sterilizing device having a simpler structure and capable of performing the washing and sterilizing operations for straws separately is required.

Domestic Patent Publication No. 10-2012-0061304 (Toothbrush cleaning device and oral condition inspection method using the same) (Published on June 13, 2012) Domestic Public Utility Model Publication No. 20-1999-0033362 (Infant Bottle and Nipple Washer and Sterilizer) (Published on August 5, 1999) Domestic Utility Model Registration No. 20-0455283 (Portable Toothbrush Sterilizer) (Publicly Announced on September 1, 2011) Domestic Patent Publication No. 10-2093993 (Multifunctional portable toothbrush sterilizer) (announced on March 26, 2020) Domestic Patent Publication No. 10-1684297 (Children's and Infants' Equipment Sterilization Device) (Publicly Announced on December 8, 2016)

The present invention has been made to improve the above-mentioned problems, and the problem that the present invention seeks to solve is to provide a portable straw sterilizing device capable of performing washing and sterilizing operations on a straw separately with a simpler structure by separating a first accommodation space in which a straw is accommodated and a second accommodation space in which a sterilizing light source that irradiates ultraviolet rays in a direction toward the straw is accommodated within a lower case and an upper case.

The technical problems of the present invention are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

In order to achieve the above object, a portable straw sterilizing device according to a first embodiment of the present invention comprises: a lower case having a first accommodation space in which a straw is accommodated therein, and a second accommodation space formed on one side of the first accommodation space and communicating with the first accommodation space; an upper case coupled to an upper portion of the lower case and sealing the first accommodation space and the second accommodation space; and a sterilizing light source unit detachably coupled to the second accommodation space and irradiating ultraviolet rays in a direction toward the straw, wherein the straw is washed by a fluid filled in the first accommodation space and the second accommodation space when the sterilizing light source unit is separated from the second accommodation space, and is sterilized by the sterilizing light source unit when the sterilizing light source unit is coupled to the second accommodation space.

In addition, in order to achieve the above object, a portable straw sterilizing device according to a second embodiment of the present invention includes a lower case having a first accommodation space in which a straw is accommodated therein, and a second accommodation space formed on one side of the first accommodation space and communicating with the first accommodation space; an upper case coupled to an upper portion of the lower case and sealing the first accommodation space and the second accommodation space; and a sterilizing light source unit rotatably coupled to both sides of the second accommodation space and irradiating ultraviolet rays in a direction toward the straw, wherein the straw is washed by a fluid filled in the first accommodation space and the second accommodation space when the sterilizing light source unit rotates around both sides of the second accommodation space and is in a first angular range, and is sterilized by the sterilizing light source unit when the sterilizing light source unit rotates around both sides of the second accommodation space and is in a second angular range.

At this time, the sterilizing light source unit is characterized by including: a sterilizing lamp that irradiates ultraviolet rays; a circuit board having the sterilizing lamp installed on the front surface facing the first receiving space; a battery installed on the rear surface of the circuit board and supplying power to the sterilizing lamp; a first housing having an receiving space formed therein in which the sterilizing lamp, the circuit board, and the battery are accommodated; and a second housing coupled to the front surface of the first housing, sealing the first receiving space, and having a through hole formed through which ultraviolet rays irradiated from the sterilizing lamp pass.

Specific details of other embodiments are included in the detailed description and drawings.

According to the portable straw sterilization device according to embodiments of the present invention, by separating a first accommodation space in which a straw is accommodated and a second accommodation space in which a sterilizing light source unit that irradiates ultraviolet rays in a direction toward the straw is accommodated within the lower case and the upper case, the washing and sterilizing operations for the straw can be performed separately with a simpler structure.

In particular, according to the portable straw sterilization device according to the first embodiment of the present invention, by detachably connecting the sterilizing light source unit that irradiates ultraviolet rays and is arranged in the second receiving space, the washing operation on the straw can be performed while the sterilizing light source unit is disassembled from the second receiving space after the straw is received in the first receiving space, and the sterilizing operation on the straw can be performed while the sterilizing light source unit is connected to the second receiving space. Therefore, both the washing operation and the sterilizing operation on the straw can be performed using one portable straw sterilization device.

In addition, according to the portable straw sterilization device according to the second embodiment of the present invention, since the sterilizing light source unit that irradiates ultraviolet rays and is arranged in the second receiving space is rotatably coupled, a washing operation or a sterilization operation can be performed on the straw according to the angle at which the sterilizing light source unit rotates around both sides of the second receiving space after the straw is received in the first receiving space, so that both the washing operation and the sterilization operation on the straw can be performed using one portable straw sterilization device.

In addition, according to the portable straw sterilizing device according to embodiments of the present invention, the straw is configured to be folded and joined along the width direction or unfolded and separated, so that when the straw is rolled up in the width direction and both side ends are joined, a drinking passage is provided, and when the straw is unfolded, the inside can be cleaned and sterilized, thereby enabling the reuse of the portable straw sterilizing device and improving user convenience in use and storage.

In addition, a charging hole (134c) through which a power terminal (133a) is exposed to the outside can be formed on the rear surface of the first housing (134), and a through hole (135a) through which ultraviolet rays irradiated from a sterilizing lamp (131) pass can be formed on the front surface of the second housing (135).

Hereinafter, with reference to FIG. 6, a method of using a portable straw sterilizing device (100) according to the first embodiment of the present invention will be described.

FIG. 6 is a drawing showing the usage state of a portable straw sterilization device according to the first embodiment of the present invention.

In (a) of FIG. 6, the sterilizing light source unit (130) is shown as being separated from the second receiving space (112) of the lower case (110), and in (b) of FIG. 6, the sterilizing light source unit (130) is shown as being coupled to the second receiving space (112) of the lower case (110).

First, as illustrated in (a) of FIG. 6, when the sterilizing light source unit (130) is separated from the second receiving space (112) of the lower case (110), the straw (10) can be cleaned by various types of fluids (C), such as water, air, and detergent, filled in the first receiving space (111) and the second receiving space (112). At this time, the straw (10) may be stored in a state where the sterilizing light source unit (130) is separated from the second receiving space (112) of the lower case (110). Conversely, as illustrated in (b) of FIG. 6, when the sterilizing light source unit (130) is coupled to the second receiving space (112) of the lower case (110), the straw (10) can be sterilized by the sterilizing light source unit (130).

In this way, the portable straw sterilization device (100) according to the first embodiment of the present invention has a simpler structure by separating a first accommodation space (111) in which a straw (10) is accommodated and a second accommodation space (112) in which a sterilizing light source (130) that irradiates ultraviolet rays in a direction toward the straw (10) is accommodated within the lower case (110) and the upper case (120), thereby enabling the washing and sterilizing operations for the straw (10) to be performed separately.

In particular, the portable straw sterilization device (100) according to the first embodiment of the present invention can perform a cleaning operation on the straw (10) while the sterilizing light source (130) is disassembled from the second receiving space (112) after the straw (10) is received in the first receiving space (111), and can perform a sterilization operation on the straw (10) while the sterilizing light source (130) is coupled to the second receiving space (112), by detachably attaching the sterilizing light source (130) that irradiates ultraviolet rays placed in the second receiving space (112). Therefore, both the cleaning operation and the sterilization operation on the straw (10) can be performed using a single portable straw sterilization device (100).

Hereinafter, with reference to FIGS. 7 to 9, the structure of the straw (10) constituting the portable straw sterilization device (100) according to the first embodiment of the present invention will be described in detail.

FIG. 7 is a perspective view showing a straw constituting a portable straw sterilization device according to the first embodiment of the present invention, FIG. 8 is a view showing a straw constituting a portable straw sterilization device according to the first embodiment of the present invention in a folded state, and FIG. 9 is a view showing a straw constituting a portable straw sterilization device according to the first embodiment of the present invention in an unfolded state.

As shown in FIGS. 7 to 9, the straw (10) may be configured to include a body portion (11), a joining groove (12), and a joining protrusion (13).

As shown in Fig. 9, the body part (11) may be formed of a thin-shaped face made of a silicone material. In addition, a joining groove (12) is formed lengthwise on one side end of the body part (11) (the right side end of the body part (11) in the example of Fig. 9), and a joining protrusion (13) is formed lengthwise on the other side end of the body part (11) (the left side end of the body part (11) in the example of Fig. 9) and can be attached to and detached from the joining groove (12).

Accordingly, the straw (10) can be folded or unfolded along the width direction (or circumferential direction), and as shown in FIG. 8, when the body part (11) is rolled in the width direction and the engaging protrusion (13) is engaged with the engaging groove (12), a hollow drinking passage (10a) is formed inside, and as shown in FIG. 9, when the body part (11) is unfolded and the engaging protrusion (13) is separated from the engaging groove (12), it can be accommodated in the first accommodation space (111) of the lower case (110).

Preferably, as illustrated in FIG. 9, the body portion (11) may be provided with folding grooves (14) formed lengthwise at predetermined intervals along the width direction on one side where the drinking passage (10a) is formed. At this time, the folding grooves (14) may be formed in multiple numbers along the width direction so as to divide the entire width of the body portion (11) into a predetermined number of equal intervals. FIG. 9 illustrates an example in which seven folding grooves (14), each having a triangular cross-section, are formed along the width direction so as to divide the entire width of the body portion (11) into eight equal intervals.

Accordingly, as shown in Fig. 8, when the body part (11) of the straw (10) is rolled up and the joining projection (13) is joined to the joining groove (12), a drinking passage (10a) can be formed in a state where each of the plurality of folding grooves (14) is folded to form a polygonal shape (an octagonal shape in the example of Fig. 8).

Meanwhile, as shown in Fig. 9, when the straw (10) is not in use, for example, when stored, the connecting projection (13) can be separated from the connecting groove (12) and the body part (11) can be spread out into a flat state. At this time, the drinking passage (10a) formed inside the straw (10) during use is exposed to the outside, so that cleaning and sterilization operations are possible.

In this way, the portable straw sterilization device (100) according to the first embodiment of the present invention is configured so that the straw (10) can be folded and joined along the width direction or unfolded and separated, thereby providing a drinking passage (10a) when the straw (10) is rolled up in the width direction and joined at both side ends, and when the straw (10) is unfolded, the inside can be cleaned and sterilized, thereby enabling the reuse of the portable straw sterilization device (100) and improving user convenience in use and storage.

Hereinafter, with reference to FIGS. 10 and 11, the structure of a portable straw sterilization device (200) according to the second embodiment of the present invention will be described. For convenience of explanation, the description of the same structure as the first embodiment illustrated in FIGS. 1 to 9 will be omitted, and only the differences will be mainly described below.

Figure 10 is an exploded perspective view showing the structure of a portable straw sterilization device according to the second embodiment of the present invention.

As illustrated in FIG. 10, the portable straw sterilization device (200) according to the second embodiment of the present invention differs from the first embodiment illustrated in FIGS. 1 to 9 in that, unlike the first embodiment, the sterilizing light source unit (230) is not detachably coupled to the second receiving space (212) of the lower case (210), but is rotatably coupled to both sides of the second receiving space (212).

That is, as illustrated in FIG. 10, the portable straw sterilization device (200) according to the second embodiment of the present invention comprises a lower case (210), an upper case (220), and a sterilizing light source unit (230), and the sterilizing light source unit (230) can be rotatably coupled to the lower case (210) through first coupling holes (h1) formed on both sides of the lower case (210) by a coupling member such as a fixing pin (P1) and second coupling holes (h2) formed on both sides of the first housing (234) and the second housing (235).

As illustrated in FIG. 10, the overall structure of the lower case (210), the upper case (220), and the sterilizing light source (230) constituting the portable straw sterilizing device (200) according to the second embodiment of the present invention is substantially the same as that of the first embodiment illustrated in FIGS. 1 to 9, and therefore, a duplicate description will be omitted.

Meanwhile, in the case of the portable straw sterilization device (200) according to the second embodiment of the present invention, the straw (20) can be washed by the fluid filled in the first accommodation space (211) and the second accommodation space (212) when the sterilizing light source unit (230) rotates around both sides of the second accommodation space (212) and is in the first angle range, and can be sterilized by the sterilizing light source unit (230) when the sterilizing light source unit (230) rotates around both sides of the second accommodation space (212) and is in the second angle range.

Hereinafter, with reference to FIG. 11, a method of using a portable straw sterilizing device (200) according to a second embodiment of the present invention will be described.

Figure 11 is a longitudinal cross-sectional view showing the state of use of a portable straw sterilization device according to the second embodiment of the present invention.

In (a) of FIG. 11, the sterilizing light source unit (230) is shown as being rotated 90 degrees around both sides of the second receiving space (212) of the lower case (210), and in (b) of FIG. 11, the sterilizing light source unit (230) is shown as being rotated 0 degrees around both sides of the second receiving space (212) of the lower case (210).

First, as shown in (a) of Fig. 11, when the sterilizing light source (230) rotates around both sides of the second receiving space (212) of the lower case (210) and is in the first angle range of 90 degrees, the straw (20) can be washed by the fluid filled in the first receiving space (211) and the second receiving space (212).

Conversely, as shown in (b) of Fig. 11, when the sterilizing light source unit (230) rotates around both sides of the second receiving space (212) of the lower case (210) and is in the second angle range of 0 degrees, the straw (20) can be sterilized by the sterilizing light source unit (230).

Meanwhile, as illustrated in (a) of FIG. 11, when the sterilizing light source unit (230) is in a first angle range, for example, 90 degrees, 180 degrees, or 270 degrees, rather than a second angle range of 0 degrees, as needed, the sterilizing light source unit (230) may sterilize an external object by irradiating ultraviolet rays to the outside through an irradiation hole (220a) formed in at least one of the lower case (210) and the upper case (220), rather than sterilizing the straw (20) accommodated in the first accommodation space (211).

In this way, the portable straw sterilization device (200) according to the second embodiment of the present invention has a simpler structure by separating a first accommodation space (211) in which a straw (20) is accommodated and a second accommodation space (212) in which a sterilizing light source (230) that irradiates ultraviolet rays in a direction toward the straw (20) is accommodated within the lower case (210) and the upper case (220), thereby enabling the washing and sterilizing operations for the straw (20) to be performed separately.

In particular, the portable straw sterilization device (200) according to the second embodiment of the present invention can perform a washing or sterilization operation on the straw (20) according to the angle at which the sterilization light source (230) that irradiates ultraviolet rays and is placed in the second receiving space (212) is rotated after the straw (20) is received in the first receiving space (211), thereby performing both the washing and sterilization operations on the straw (20) using one portable straw sterilization device (200).

Meanwhile, the present specification and drawings have disclosed preferred embodiments of the present invention, and although specific terms have been used, they have been used only in a general sense to easily explain the technical contents of the present invention and to help understand the invention, and are not intended to limit the scope of the present invention. It will be apparent to those skilled in the art that other modified examples based on the technical idea of the present invention can be implemented in addition to the embodiments disclosed herein.
