Description

Technical Field

[0001] The present invention relates to a functional solution injection module provided with a cover unit for lubricating coating, and relates to a functional solution injection module provided with a cover unit for lubricating coating, which is convenient to use by performing a simple lubricating coating before using the injection unit containing functional solution inside, a method of using the module, and a kit including the module. Background Art

[0002] Generally, there are many cases in recent years where various liquids are injected into the human body for various purposes.

[0003] For example, there are many different ways of application, such as administering a cleaning solution for cleaning the female genitals or administering a contraceptive solution for contraception, administering a solution for treating hemorrhoids, sexually transmitted diseases, etc., and injecting a lubricant during sexual intercourse.

[0004] In this case, the inside of the human body's genitals and anus, etc., as exposed mucous membranes, are very sensitive to external stimuli and are easily damaged or contaminated. Therefore, in order to administer the various liquids listed above, great care must be taken.

[0005] In the past, in order to improve the inconvenience of directly manually administering the above-mentioned liquid, a tool for administering liquid into the body was invented. Such liquid administration tools are usually made disposable due to hygiene issues and difficulty in cleaning, and are therefore sold in a state where the liquid is pre-contained therein.

[0006] However, when a user administers liquid into the human body, the device must be inserted into the human body for administration. In this case, there is a problem that pain may occur due to friction during insertion into the human body.

[0007] Therefore, a new method that can solve this problem is needed. Summary of the invention

[0039] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in the process of describing the present invention, in order to clarify the gist of the present invention, descriptions of known functions or structures will be omitted.

[0040] At the same time, in the process of describing the present invention, terms indicating directions such as front / rear or upper / lower are recorded to enable those skilled in the art to clearly understand the present invention. They indicate relative directions, and the scope of protection claimed in the invention will not be limited thereby.

[0041] First, refer to Figures 1 to 5 The structure of one embodiment of a functional solution injection module provided with a lubricating coating cover unit, a method of using the same, and a kit including the same according to the present invention will be described in detail.

[0042] Figure 1 This is a diagram briefly showing the structure of a functional solution injection module provided with a lubricating coating cover unit according to the present invention. Figure 2 This is a diagram showing the interior of a functional solution injection module provided with a lubricating coating cover unit according to the present invention.

[0043] and, Figure 3 To show Figure 2 A diagram showing a state in which a coating space and the inside of the injection unit are connected by a sliding cover unit in a functional solution injection module provided with a cover unit for lubricating coating, Figure 4 To show Figure 3 A functional solution injection module provided with a lubricating coating cover unit is provided with a state where a coating liquid is applied to the front end of the injection unit, Figure 5 To show Figure 1 A diagram of a functional solution injection module provided with a cover unit for lubricating coating, in which a cover unit is separated from an injection unit.

[0044] As shown in the figure, the functional solution injection module provided with a cover unit for lubricating coating of the present invention generally includes an injection unit 100 and a cover unit 200 .

[0045] The injection unit 100 is in the form of a common syringe, which is filled with the functional solution 10 and can selectively eject the functional solution 10 through the operation of the user.

[0046] Specifically, the injection unit 100 is long and has a space inside that can accommodate the functional solution 10, and a discharge port 112 is formed at the front section to discharge the functional solution 10. In this embodiment, the injection unit 100 generally includes a body 110 and a piston 120. In this case, the functional solution 10 is a liquid injected into the user's body, usually using a lubricant, a detergent or a liquid medicine, and can be made into a form that is harmless to the human body.

[0047] The body 110 is elongated so as to be inserted into the body, and has a space therein for receiving liquid. A discharge port 112 is formed at the front end of the body 110 so as to eject the liquid received therein, and the rear end of the body 110 is opened so as to insert the piston 120 therein.

[0048] In this embodiment, the body 110 extends in the front-rear direction, is formed in an arc shape as a whole, and has a circular cross section. Therefore, when inserted into the body, it will not cause pain to the user. In addition, the rear end of the body 110 is formed so that the cross-sectional area gradually increases, so that the piston 120 can be easily inserted.

[0049] Moreover, in the present embodiment, an additional first coupling portion 114 is formed on at least a portion of one outer surface along the length direction of the body 110 .

[0050] The first combination part 114 is combined with the second combination part 220 described later, so that the injection unit 100 and the cover unit 200 can maintain a combined state. In this case, when the first combination part 114 is combined with the second combination part 220, it is combined in the first form or the second form, which will be described in the following content.

[0051] In this embodiment, the first coupling portion 114 is formed in a protruding form to protrude toward the outer surface of the upper body 110, and is formed along the periphery at least in a portion. Moreover, it is coupled to the second coupling portion 220 formed in the cover unit 200 described later. In this case, the first coupling portion 114 is configured in the form of one or more protruding portions spaced apart from each other by a preset length along the length direction of the body 110.

[0052] Specifically, as shown in the figure, the first coupling portion 114 includes: a first protrusion 114a, which is formed protruding from the body 110 along the periphery; and a second protrusion 114b, which is separated from the first protrusion 114a by a preset interval. Moreover, the cover unit 200 described later is coupled with at least one of the first protrusion 114a or the second protrusion 114b, and becomes the first form or the second form according to the coupled state.

[0053] As described above, the main body 110 of the present invention is in an elongated shape, and is configured to discharge the functional solution 10 contained therein through the discharge port 112 at the front. In addition, the first connecting portion 114 is formed on the outer surface along the periphery.

[0054] On the other hand, the piston 120 is inserted in a manner that it can move forward and backward through the open rear end of the body 110. That is, when the piston 120 is moved forward in a state of being inserted into the body 110, the functional solution 10 contained in the body 110 is pushed and ejected through the discharge port 112.

[0055] In the present embodiment, although not shown in the figure, a separate sealing member (not shown in the figure) is provided at the front end of the piston 120, and the sealing member can be pushed to move forward as the piston 120 moves forward.

[0056] Therefore, the front end of the piston 120 is inserted from the rear end of the body 110 and can apply pressure to the functional solution 10 and eject it by sliding along the length direction.

[0057] As described above, the injection unit 100 of the present invention is formed in the form of a syringe in which the body 110 and the piston 120 are combined, and the functional solution 10 contained in the containing space can be selectively discharged through the discharge port 112 formed at the front end. In addition, the first coupling portion 114 formed on the outer surface of the body 110 is combined with the cap unit 200.

[0058] On the other hand, the cover unit 200 is a structure that surrounds at least a portion of the injection unit 100 and surrounds the front discharge port 112 , and generally includes a cover portion 230 , a blocking portion 210 , and a second coupling portion 220 .

[0059] The cover 230 has a receiving space inside and is selectively fixed by inserting at least a portion of the injection unit 100 through an opening formed on one side. That is, the cover 230 is configured to surround the injection unit 100 by being fixed in a state where a portion of the injection unit 100 is inserted into the receiving space.

[0060] Specifically, the cover 230 is elongated and has an inner diameter relatively larger than the periphery of the body 110, and forms a receiving space inside to receive at least a portion of the injection unit 100. In this case, as shown in the figure, by having an inner diameter relatively larger than the periphery of the body 110, when the injection unit 100 is inserted into the receiving space or separated to the outside, the body 110 can be stably surrounded without causing any obstruction.

[0061] In this embodiment, as shown in the figure, the cover portion 230 has a U-shaped cross section, and the front end portion of the body 110 is inserted into the interior of the receiving space through the opening formed on one side.

[0062] On the other hand, the blocking portion 210 is formed to protrude from the inner surface of the cover 230 and at least a portion thereof is inserted into the discharge port 112 to adjust the opening and closing. Specifically, the blocking portion 210 is formed in a protrusion shape and protrudes from the inside of the receiving space toward the opening.

[0063] Therefore, when the body 110 is inserted into the receiving space through the opening to a depth greater than a predetermined depth, the blocking portion 210 is inserted into the discharge port 112 to block discharge of the functional solution 10 .

[0064] In this embodiment, the blocking portion 210 has an outer diameter corresponding to the size of the outlet 112 and is formed to protrude with a predetermined length. In this case, the blocking portion 210 has a length relatively smaller than the spacing distance between the first protrusion 114a and the second protrusion 114b and is formed to protrude.

[0065] As described above, as the body 110 is inserted into the cover 230 , the blocking portion 210 may block the outlet 112 , and the opening and closing of the outlet 112 may be selectively adjusted according to the insertion depth of the body 110 .

[0066] On the other hand, the second coupling part 220 is a structure fastened to the first coupling part 114, and one or more are formed inside along the length direction of the cover part 230. Specifically, when the second coupling part 220 is coupled to the first coupling part 114 on the cover part 230, it is coupled in any of the first form or the second form, and the discharge port 112 can be opened in a state where the cover part 230 is coupled to the injection unit 100 according to each form.

[0067] In this case, one of the first coupling portion 114 and the second coupling portion 220 is formed in a protruding shape, and the other is formed in a recessed groove shape to engage with each other.

[0068] That is, the first combining portion 114 and the second combining portion 220 are respectively formed in the form of a protrusion and a groove, any of which are separated from each other along the length direction to form a plurality of them, and are combined in either the first form or the second form according to the combining position.

[0069] In this embodiment, the first coupling portion 114 is formed in the form of a protruding protrusion, and the second coupling portion 220 is correspondingly formed in the form of a groove inserted into the first coupling portion 114. The second coupling portion 220 is formed to protrude from the outer surface of the injection unit 100 along the periphery, and the second coupling portion 220 is formed to be recessed along the periphery on the inner surface of the cover portion 230 to insert at least a portion of the first coupling portion 114.

[0070] In this case, as shown in the figure, the first combination part 114 and the second combination part 220 form a pair and are arranged to be spaced apart from each other by a predetermined length along the length direction of the cover, and when each of the first combination part 114 and the second combination part 220 is combined at the same time, the cover unit 200 and the injection unit 100 are combined in the first form. Moreover, when the first combination part 114 is combined with a part of the second combination part 220, the cover unit 200 and the injection unit 100 are combined in the second form.

[0071] When the first coupling portion 114 is only partially coupled to the second coupling portion 220 in the second form, the cover unit 200 is coupled to the injection unit 100 while being partially moved forward, so that the discharge port 112 is opened.

[0072] That is, when the cap unit 200 and the injection unit 100 are combined in the second form, the front end of the injection unit 100 is disposed in the accommodation space in a form in which the discharge port 112 is opened.

[0073] Therefore, in the second form, when the user discharges the functional solution 10 into the accommodation space through the discharge port 112, the functional solution 10 is applied to the outer surface of the injection unit 100 through the cover unit 200. In this way, before using the injection unit 100, the functional solution 10 is applied to the outer surface of the injection unit 100 to facilitate injection into the user's body.

[0074] As described above, the cover unit 200 of the present invention includes the cover portion 230, the blocking portion 210 and the second combining portion 220, and is selectively combined with the injection unit 100 in any one of the first form or the second form. In the second form, the functional solution 10 can be applied to the outer surface of the injection unit 100.

[0075] Next, in the functional solution injection module of the present invention, the structures of the first combining portion 114 and the second combining portion 220 are examined in more detail, as follows.

[0076] In the present invention, the first combining portion 114 includes a pair of first protrusions 114a and a second protrusion 114b separated from each other along the length direction of the injection unit 100, and the second combining portion 220 includes a pair of first grooves 222 and a second groove 224 separated from each other along the length direction of the cover unit 200 at the same length as the separation distance of the first combining portion 114.

[0077] As shown in the figure, the first protrusion 114a and the second protrusion 114b are formed along the periphery at least partially from the outer surface of the injection unit 100, are composed of one or more and protrude radially. In this case, the first protrusion 114a and the second protrusion 114b are formed in a similar form and are configured to be able to be combined with the second combining portion 220 described later.

[0078] In this embodiment, the first protrusion 114a and the second protrusion 114b are formed in a ring shape along the periphery of the injection unit 100 and are spaced apart from each other at a preset distance. In this case, the first protrusion 114a and the second protrusion 114b are formed in the same shape, and their size (thickness) is formed in a shape that decreases toward the outside along the periphery. In this case, the first protrusion 114a and the second protrusion 114b can be radially protruded along the periphery and spaced apart from each other, rather than in a ring shape as shown in the figure.

[0079] On the other hand, the second coupling portion 220 includes the first groove 222 and the second groove 224 corresponding to the first protrusion 114a and the second protrusion 114b. The first groove 222 and the second groove 224 are spaced apart from each other corresponding to the spacing distance of the first protrusion 114a and the second protrusion 114b, and are formed to be able to insert at least a part of the first protrusion 114a and the second protrusion 114b. In this case, the first groove 222 and the second groove 224 are formed in a shape corresponding to the first protrusion 114a and the second protrusion 114b, and preferably, the depth of the recess is equal to or relatively smaller than the protruding length of the first protrusion 114a and the second protrusion 114b.

[0080] As described above, the second coupling portion 220 includes the first groove 222 and the second groove 224, which are spaced apart from each other to correspond to the spacing distance between the first protrusion 114a and the second protrusion 114b. Moreover, as the first groove 222 and the second groove 224 are spaced apart from each other, the first protrusion 114a and the second protrusion 114b are inserted and coupled, respectively, so that the injection unit 100 and the coupling unit are coupled in any one of the first form or the second form.

[0081] As described above, the first coupling portion 114 and the second coupling portion 220 of the present invention are respectively disposed on the cover unit 200 and the injection unit 100 in a manner facing each other, and are selectively coupled to each other in either the first form or the second form.

[0082] Among them, Figure 2As shown, the first form is a state in which the first groove 222 is combined with the first protrusion 114a and the second groove 224 is combined with the second protrusion 114b. Figure 3 As shown, the second state is a state where the first groove 222 is combined with the second protrusion 114 b.

[0083] Moreover, when the functional solution injection module of the present invention is not used, the above-mentioned cover unit 200 is combined with the above-mentioned injection unit 100 in the above-mentioned first form, and the discharge of the above-mentioned functional solution 10 is blocked by inserting the above-mentioned blocking portion 210 into the above-mentioned discharge port 112. When the above-mentioned functional solution injection module is used, the position of the above-mentioned cover unit 200 is operated to be combined with the above-mentioned injection unit 100 into the above-mentioned second form, so that the above-mentioned functional solution 10 can be applied to the area located inside the above-mentioned cover unit 200 on the outer surface of the above-mentioned injection unit 100 with the above-mentioned discharge port 112 opened.

[0084] Afterwards, the user separates the cap unit 200 from the injection unit 100 and inserts the injection unit 100 into the human body for use in a state where a portion of the functional solution 10 is applied to the outer surface of the injection unit 100 and is punctured.

[0085] As described above, the functional solution injection module of the present invention is sealed and stored in the first form. When in use, it is operated to the second form to apply a portion of the functional solution 10 to the outer surface of the injection unit 100, and then the cover unit 200 is separated to use the injection unit 100, so that when inserted into the human body, the friction caused by contact can be minimized and the insertion can be easy.

[0086] In addition, the structure of the blocking portion 210 of the present invention is examined in detail, and the specific contents are as follows.

[0087] First, the blocking portion 210 has an outer diameter corresponding to the size of the discharge port 112 and is formed to be relatively smaller than a distance between the first protrusion 114 a and the second protrusion 114 b .

[0088] Specifically, as shown in the figure, when the cap unit 200 and the injection unit 100 are combined in the first form, the blocking portion 210 is inserted into the inside of the discharge port 112, and when they are combined in the second form, the blocking portion 210 is separated to the outside of the discharge port 112. In this case, when the protruding length of the blocking portion 210 is greater than the spacing distance between the first protrusion 114a and the second protrusion 114b, the blocking portion 210 will not be able to be completely separated from the discharge port 112 in the second form.

[0089] Therefore, preferably, the protruding length of the blocking portion 210 is formed to be relatively shorter than the spacing distance between the first protrusion 114 a and the second protrusion 114 b .

[0090] On the other hand, the blocking portion 210 of the present invention may be formed of a single double structure different from the above-mentioned structure, so that the circumference of the outer diameter is different.

[0091] Specifically, the blocking portion 210 may include a blocking region formed to be relatively shorter than a spacing distance between the first protrusion 114 a and the second protrusion 114 b , and an auxiliary region extending from the blocking region and penetrating into the discharge port 112 .

[0092] The blocking region is similar to the above embodiment, having an outer diameter corresponding to the size of the outlet 112, and a protruding length shorter than the spacing distance between the first protrusion 114a and the second protrusion 114b. Furthermore, the auxiliary region is formed to protrude from the terminal end of the blocking region and penetrate into the outlet 112.

[0093] In this case, the auxiliary region is configured to have an outer diameter relatively smaller than the size of the discharge port 112 , and thus may form a multi-layer structure together with the blocking region.

[0094] Therefore, in the first form, the blocking area and the auxiliary area are both inserted into the outlet 112, but in the second form, the blocking area is located outside the outlet 112 and at least a portion of the auxiliary area penetrates into the outlet 112.

[0095] In this case, although the auxiliary region is inserted into the discharge port 112, due to its relatively small outer diameter, a portion of the discharge port 112 is opened to discharge the functional solution 10 into the accommodation space.

[0096] As described above, since the blocking portion 210 is formed to include the blocking area and the auxiliary area, even if the cover unit 200 is combined with the injection unit 100 in the second form, a portion of the blocking portion 210 is configured to pass through the discharge port 112, so that the cover unit 200 can be supported on the injection unit 100.

[0097] Next, refer to Figure 6 , looking at the detailed structure of the first combining portion 114 and the second combining portion 220 of the present invention, the specific contents are as follows.

[0098] Figure 6 To show Figure 1FIG. 2 is a diagram showing a detailed combination structure of a cover unit 200 and an injection unit 100 in a functional solution injection module provided with a cover unit 200 for lubricating coating.

[0099] As shown in the figure, the first protrusion 114a and the second protrusion 114b are respectively formed on the outer surface of the injection unit 100 and arranged along the periphery, and the first groove 222 and the second groove 224 are respectively formed on the cover unit 200 and combined with the injection unit 100 in a first form.

[0100] In this case, the protruding heights of the first protrusion 114a and the second protrusion 114b as the first coupling portion 114 are formed to be relatively greater than the recessed depths of the first groove 222 and the second groove 224 as the second coupling portion 220. That is, although the first coupling portion 114 is formed in a protruding form, it is formed in a form in which the first coupling portion 114 is entirely inserted into the inside of the groove-shaped second coupling portion 220 or only a portion is inserted.

[0101] Therefore, the inner surface of the cover 230 and the outer surface of the injection unit 100 have a separation distance of degree T corresponding to the difference between the protruding length of the first protrusion 114a and the recessed depth of the first groove 222. Therefore, the inner surface of the cover 230 and the outer surface of the injection unit 100 are not actually in contact with each other except for the first coupling portion 114 and the second coupling portion 220, and are separated from each other, thereby preventing friction or sliding from occurring between them.

[0102] Furthermore, by forming a space between the cap unit 200 and the injection unit 100 and then combining them in the second form, the functional solution 10 discharged through the discharge port 112 can be applied to the space formed in the cap unit 200 without leaking to the outside.

[0103] In the present embodiment, the first coupling portion 114 is formed in a protruding protrusion shape, and the second coupling portion 220 is formed in a recessed groove shape, but the two may also be formed in the opposite manner.

[0104] As described above, in the functional solution injection module of the present invention, the first combining portion 114 and the second combining portion 220 are respectively formed in the form of a protrusion and a groove, and the protrusion is formed to be relatively longer to form a T-level separation distance between the cover unit 200 and the injection unit 100, thereby reducing obstruction by minimizing the contact between them, and at the same time forming a space in which the functional solution 10 can be applied to the outer surface of the injection unit 100.

[0105] The functional solution injection module can discharge the functional solution 10 to the outside and open the discharge port 112 by increasing the pressure inside the body 110 when the user applies pressure to the piston 120. That is, by pressurizing the piston 120, the discharge port 112 can be opened with a simple pressure without the need for additional operation of the cover unit 200, so the combination state of the cover unit 200 and the injection unit 100 can be changed from the first state to the second state.

[0106] Next, refer to Figures 7 to 9 , observe the deformed form of the functional solution injection module of the present invention, the specific contents are as follows.

[0107] Figure 7 To show Figure 1 FIG. 2 is a diagram showing a deformed state of the cover unit 200 in the functional solution injection module. Figure 8 To show Figure 1 FIG. 1 is a diagram showing a reduced diameter morphology of the injection unit 100 in the functional solution injection module, Fig. 9 To show in Figure 1 FIG. 1 is a diagram of a functional solution injection module formed in a manner of having a uniform diameter in a state in which the cover unit is coupled to the injection unit.

[0108] First, as shown in the drawings, the cap unit 200 is deformed so as to have a length relatively shorter than that of the injection unit 100 and to surround only a portion of the front end of the injection unit 100 .

[0109] Specifically, the cover unit 200 shown only surrounds a portion of the front end of the injection unit 100, and accordingly, the injection unit 100 forms the first coupling portion 114 around the front end. Moreover, the cover unit 200 also forms the second coupling portion 220 corresponding to the position of the first coupling portion 114.

[0110] Therefore, when the cap unit 200 and the injection unit 100 are arranged in the second form, the accommodation space is formed only at the front end of the injection unit 100 by the cap unit 200, so that the functional solution 10 can be applied to the outer surface.

[0111] That is, the cover unit 200 of the present invention includes the front end portion of the injection unit 100 regardless of the length of the injection unit 100, so as to be configured to form the accommodation space. If it can be combined in the first form or the second form through the first combining portion 114 and the second combining portion 220, it can be composed of various lengths.

[0112] On the other hand, Figure 8As shown, the structure around the injection unit 100 is different from the above content.

[0113] Specifically, unlike the above, the injection unit 100 can be formed in a shape in which the outer diameter gradually decreases toward the front end. In particular, when the inner diameter of the cover unit 200 is formed uniformly along the length direction, as in the present embodiment, the outer diameter of the front end of the injection unit 100 is formed to be relatively smaller, so that the accommodation space formed by the cover unit 200 can be formed at the front end of the injection unit 100.

[0114] Therefore, as shown in the figure, the front end of the injection unit 100 and the inner surface of the cover unit 200 are separated from each other to form the receiving space, so that relatively more functional solution 10 can be applied to the front end of the injection unit 100.

[0115] In addition, if Fig. 9 As shown, the basic form is similar to the above Figure 7 The injection unit 100 is similar to the injection unit 100, but the outer diameters of the middle and rear ends of the injection unit 100 are the same as the outer diameter of the cap unit 200. Specifically, the cap unit 200 is configured to surround only a portion of the front end of the injection unit 100, and the front end of the injection unit 100 is formed to be relatively smaller corresponding to the inner diameter of the cap unit 200.

[0116] Furthermore, the outer diameter of the cap unit 200 is formed to be the same as or similar to the outer diameter of the end portion of the injection unit 100 , so that when the injection unit 100 and the cap unit 200 are combined, the cap unit 200 is formed to have a uniform circumference with the injection unit 100 .

[0117] That is, the front end portion of the injection unit 100 is formed to have a relatively small outer diameter corresponding to the size and inner diameter of the cover unit 200, so that even if the cover unit 200 is combined, the cover unit 200 will have an outer diameter of similar size and be continuously configured along the length direction of the injection unit 100.

[0118] As described above, in the functional solution injection module of the present invention, the cover unit 200 is only formed at the front end of the injection unit 100, or the outer diameter of the front end of the injection unit 100 is formed to be relatively smaller, so that the receiving space can be formed at the front end of the injection unit 100 to apply the functional solution 10 to the front end of the injection unit 100.

[0119] Next, refer to Fig.10 , observing the deformation forms of the above-mentioned first combining portion 114 and the above-mentioned second combining portion 220 of the present invention, the specific contents are as follows.

[0120] Fig.10 To show Figure 1 A diagram showing the morphological deformation of the first and second combining parts in the functional solution injection module.

[0121] As shown in the figure, the first coupling portion 114 is formed in a groove shape, and the second coupling portion 220 is formed in a protrusion shape, so that the cover unit 200 is formed in a shape in contact with the outer surface of the injection unit 100 .

[0122] Specifically, the pair of first combining parts 114 are respectively formed in the form of grooves and are spaced apart from each other along the length direction. Corresponding to the shape of the first combining parts 114, the pair of second combining parts 220 are spaced apart from each other and are spaced apart from each other along the length direction.

[0123] In this case, if Fig.10 As shown in part (a) of FIG. 1 , the first combining portion and the second combining portion 220 are combined and configured in a first form, such as Fig.10 As shown in part (b) of FIG. 1 , when in use, the cover unit 200 moves toward the front end by a predetermined distance so that a portion of the second coupling portion 220 is inserted into the first coupling portion 114 .

[0124] That is, Fig.10 As shown, different from the first embodiment, in the first combining portion 114 and the second combining portion 220, the first combining portion 114 is formed in a groove shape and the second combining portion 220 is formed in a protrusion shape, so that they can be combined with each other in the first shape or the second shape.

[0125] As described above, in the functional solution injection module of the present invention, the first combining portion 114 and the second combining portion 220 can be formed into various mutually combining forms, and thus, are configured to easily change the combination and combination form of the cover unit 200 and the injection unit 100.

[0126] Next, refer to Fig.11 as well as Fig.12 , observe the changed morphology of the first combining part and the second combining part in the functional solution injection module of the present invention, the specific contents are as follows.

[0127] Fig.11 To show Figure 1 A diagram showing a state in which the first joint part and the second joint part in the functional solution injection module are formed in a threaded form, Fig.12 To show Fig.11 A diagram of a state in which the cover unit in the functional solution injection module is separated.

[0128] As shown in the figure, the basic form is formed into a structure similar to the first embodiment, but the structures of the first combining portion 114 and the second combining portion 220 are different.

[0129] Specifically, at least one of the first coupling portion 114 or the second coupling portion 220 is formed in a threaded form, and the other is configured to mesh with it accordingly. Furthermore, by the relative rotation of the injection unit 100 and the cover unit 200, the cover unit 200 is moved forward by a predetermined distance, so that the coupling form can be adjusted to the first form or the second form.

[0130] In this case, when the first coupling portion 114 is formed in a threaded form, it is formed along the outer surface of the body 110 , and when the second coupling portion 220 is formed in a threaded form, it is configured to be formed along the inner diameter of the cover unit 200 .

[0131] In this embodiment, the first coupling portion 114 and the second coupling portion 220 are both formed in a threaded form and configured to engage with each other, changing from the first form to the second form or completely separating the cover unit 200 from the injection unit 100 according to the degree of rotation of the cover unit 200.

[0132] Of course, differently from this, only one of the first coupling portion 114 or the second coupling portion 220 may be formed into a threaded shape, and the other may be simply formed into a groove or protrusion shape and located in the thread, so as to be configured to maintain the coupled state.

[0133] As described above, the first coupling portion 114 and the second coupling portion 220 can also be formed in a threaded form instead of the protrusions configured to be separated from each other as described above. Therefore, they can be easily changed into the first form or the second form by relative rotation of the cover unit 200, thereby preventing the coupling state from being accidentally changed due to external force.

[0134] Although specific embodiments of the present invention are described and illustrated above, the present invention is not limited to the described embodiments, and various modifications and changes can be made to the present invention without departing from the concept and scope of the present invention, which is obvious to those skilled in the art. Therefore, such modified examples or variations should not be understood separately from the technical concept or viewpoint of the present invention, and the modified embodiments should be deemed to belong to the scope of the invention claimed by the present invention.
