FIG. 4 is a cross-sectional view showing the use of a toilet plunger according to an exemplary embodiment of the invention. - Reference will now be made in detail to various embodiments of the present invention, examples of which are illustrated in the accompanying drawings and described below. While the invention will be described in conjunction with exemplary embodiments, it is to be understood that the present description is not intended to limit the invention to those exemplary embodiments. On the contrary, the invention is intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments that may be included within the spirit and scope of the invention as defined by the appended claims.
- Throughout this document, reference should be made to the drawings, in which the same reference numerals and signs are used throughout the different drawings to designate the same or similar components.
- A toilet plunger 100 according to an exemplary embodiment of the invention includes a
gas container 110, abody 120, apuncture pin 130, acover 140, and aninsert 150, in which theinsert 150 is inserted into anS trap 15 connected to atoilet bowl 10, after which thecover 140 is rotated, so that a drain can be plunged by instantaneous high pressure. - The
gas container 110 serves to contain high-pressure gas that is intended to be discharged in order to unclog the drain of thetoilet bowl 10, and is extended a predetermined length, with anopening 112 connected to the inner space thereof. - The opening 112 is closed using a
thin closing plate 114 after the high-pressure gas is supplied into the space inside thegas container 110 through theopening 112, so that the high-pressure gas contained therein does not leak to the outside. - Here, the
closing plate 114 is punctured by thepuncture pin 130 in response to manipulation of the toilet plunger by a user, so that high-pressure gas that is contained inside theclosing plate 114 is discharged toward the drain through apassage 125 in thebody 120. - The high-pressure gas contained inside the
gas container 110 is one selected from among CO2, N2, and O2. Here, CO2 is contained in the form of dry ice or liquid, and N2, and O2 are contained in the form of compressed gas. The gas is contained in an amount of about 5 to 6 liters under a pressure of 10 kg/mm2 inside thegas container 110. - However, it should be understood that this is not intended to limit the type, pressure, or amount of gas to be contained in the
gas container 110. Rather, the type, pressure, or amount of gas can be variously changed depending on the circumstance, such as use or size. - The
body 120 serves as a passage through which the high-pressure gas discharged from thegas container 110 flows. Thebody 120 is formed as a hollow structure having a predetermined length, with an inner space extending in the lengthwise direction thereof. The open upper portion is closed by being coupled to thecover 140, and the open lower portion is connected to theinsert 150. - As shown in
FIG. 2 , a pair ofpartitions 122 is arranged inside thebody 120 such that thepartitions 122 face each other at a predetermined interval, so that the space inside thebody 120 is divided into the upper and lower areas. Since thepartitions 122 are spaced apart from each other at the predetermined interval, the space defined in the central area forms a puncture pin-receivingportion 124, into which thepuncture pin 130 is fitted. - That is, the
body 120 has a gas container-receivingportion 123 in the upper portion thereof, which is defined by the pair ofpartitions 122, which divide the space inside thebody 120 into the upper and lower areas. The lower area of the space inside thebody 120 forms thepassage 125, through which the high-pressure gas discharged from thegas container 110 can travel to theinsert 150. The gas container-receivingportion 123 and thepassage 125 are connected to each other via the puncture pin-receivingportion 124. - Consequently, after the opening of the
gas container 110 is fitted into the gas container-receivingportion 123, if theclosing plate 114 is torn by thepuncture pin 130, the high-pressure gas stored in thegas container 110 is discharged into thepassage 125 through thepuncture pin 130. - Here, the
partitions 122 can havesafety passages 126 formed around the puncture pin-receivingportion 124, thesafety passages 126 connecting the gas container-receivingportion 123 to thepassage 125. - In the
toilet plunger 100 of this embodiment, when theclosing plate 114 is punctured by thepuncture pin 130, the high-pressure gas is discharged toward thepassage 125 through thepuncture pin 130. At this time, a user can be injured by repulsive power if very high pressure is generated instantaneously. - The
safety passages 126 serve as a safety means that protects the user from the danger of injury. Specifically, thesafety passages 126 lower the pressure under which the high-pressure gas is discharged by allowing a portion of the high-pressure gas that is discharged toward thepassage 125 from thegas container 110 to travel to thepassage 125 through thesafety passages 126. - As shown in the figures, the gas container-receiving
portion 123 is depressed to a predetermined depth from the upper end to form a shape that is substantially the same as that of thegas container 110, such that one portion of thegas container 110, specifically, the portion in which theopening 112 is formed, can be fitted into the gas container-receivingportion 123. - The lower portion of the gas container-receiving
portion 123, which is connected to the puncture pin-receivingportion 124, is narrowed such that theopening 112 of thegas container 110 can be positioned therein. - Consequently, the portion of the
gas container 110 in which theopening 112 is formed is inserted into the gas container-receivingportion 123, and the other portion of thegas container 110, which is closed, is inserted into thecover 140, which will be described later, so that thegas container 110 is seated in the upper portion of thebody 120. - Here, the
cover 140 is screw-coupled to the upper portion of thebody 120 to cover the gas container-receivingportion 123, such that thegas container 110 is not exposed to the outside. Specifically,first threads 121 are formed in the upper portion of thebody 120 andsecond threads 142 corresponding to thefirst threads 121 are formed in the inner circumference of thecover 140, such that thecover 140 is screw-coupled to the upper portion of thebody 120. - Here, as described above, the
cover 140 has arecess 144 in the portion thereof that is connected to thebody 120. Therecess 144 is depressed to a predetermined depth such that the portion of thegas container 110 can be fitted thereinto. - That is, the
gas container 110 is fitted into thetoilet plunger 100, with one portion thereof, including theopening 112, arranged in the gas container-receivingportion 123, and the other portion thereof fitted into therecess 144 in thecover 140. - Consequently, the
toilet plunger 100 of this embodiment can be reused by replacing thegas container 110, from which gas is discharged, with a new one by opening the upper portion of thebody 120 by rotating thecover 140 in one direction. - In addition, since the
cover 140 is screw-coupled to the upper portion of thebody 120, when thecover 140 is rotated in the other direction, thecover 140 gradually moves down along the outer circumference of thebody 120 according to a screw motion. - Consequently, the
gas container 110, with one portion thereof fitted into thecover 140, is displaced downward in response to the movement of thecover 140 so that theclosing plate 114 thereof is punctured by thepuncture pin 130, which is fitted into the puncture pin-receivingportion 124, thereby discharging the high-pressure gas contained in thegas container 110 into thepassage 125. - In the meantime, the
puncture pin 130 is fitted into the puncture pin-receivingportion 124 formed in thebody 120 such that it can puncture theclosing plate 114 of thegas container 110, which is moved downward when thecover 140 is rotated. - It is preferred that a
hollow coupling ring 160 having an open central portion be additionally provided such that thepuncture pin 130 is fitted into thecoupling ring 160, which is fitted in this state into the puncture pin-receivingportion 124. - That is, the
coupling ring 160 is interference-fitted into the puncture pin-receivingportion 124 in order to support thepuncture pin 130 such that thepuncture pin 130 can be fixed in a predetermined position. In addition, thecoupling ring 160 is made of a shrinkable or elastic material such as urethane, so that it can be fitted into the puncture pin-receivingportion 124. - The
puncture pin 130 is configured such that a through-passage 132, which allows gas to pass through, is formed in the central portion thereof. When thepuncture pin 130 is fitted into the puncture pin-receivingportion 124, the sharp upper portion of thepuncture pin 130 protrudes a predetermined height from the upper surface of thecoupling ring 160. Consequently, when thegas container 110 moves downward, the upper portion of thepuncture pin 130 can puncture theclosing plate 114. - In addition, a hollow pressing
member 170 can be coupled to thebody 120 such that it surrounds the outer surface of thebody 120. The pressingmember 170 is hollow, and extends a predetermined length such that it can press the portion of the outer circumference of thebody 120, in which the puncture pin-receivingportion 124 is formed. - That is, the pressing
member 170 is interference-fitted around the outer surface of thebody 120 to provide inward compressive force to the outer surface of thebody 120. This is intended to press thepuncture pin 130, which is fitted into the puncture pin-receivingportion 124, by applying the compressive force from the pressingmember 170 to the puncture pin-receivingportion 124, so that thepuncture pin 130 is securely fixed without moving up or down. - Here, one or more
anti-slip grooves 172 can be formed along the outer circumference in the outer surface of thepressing member 170. Theanti-slip grooves 172 are depressed a predetermined depth. - When the user attempts to rotate the
cover 140 in one direction with one hand while grasping thepressing member 170 with the other hand, theanti-slip grooves 172 prevent the other hand from slipping on thepressing member 170, so that the user can easily rotate thecover 140. - The
insert 150, which is connected to the lower portion of thebody 120, is inserted into the drain, which is connected to the toilet. In this position, theinsert 150 serves to guide the high-pressure gas that is discharged from thegas container 110 toward the drain. - A portion of the
insert 150, which is intermediate in length, is bent a predetermined angle in one direction such that theinsert 150 can be easily inserted into the drain. In general, theS trap 15 is provided at one end of the drain, which is connected to the toilet, in order to prevent a bad smell, which occurs from the inside of the drain, from exiting through thetoilet bowl 10. - In the
toilet plunger 100 of this embodiment, since the portion of theinsert 150, which is intermediate in length, is bent, theinsert 150 can be correctly inserted into the bent S trap and guide the high-pressure gas to be properly discharged into the drain. - Consequently, the high-pressure gas that that is discharged from the
gas container 110 through the passage and theinsert 150 into the drain can be properly supplied to the drain, thereby easily removing impurities from the drain. - The
insert 150 is hollow, and the lower portion of thebody 120 is interference-fitted into the upper portion of theinsert 150. In addition, theinsert 150 has astopper 152 in order to limit the depth to which the lower portion of thebody 120 is inserted upward. Thestopper 152 protrudes inwards a predetermined length, so that the lower end of thebody 120 is blocked and fixed in position by thestopper 152. - The
insert 150 also has aclose contact plate 154 along the outer circumference in the upper portion thereof. Theclose contact plate 154 protrudes outwards a predetermined length. When theinsert 150 is inserted into the toilet hole and is connected to the drain, theclose contact plate 154 covers and closes the surroundings of the toilet hole, thereby preventing the discharged high-pressure gas from flowing backwards. - In addition, the
close contact plate 154 comes in close contact with the surroundings of the toilet hole to support force that the user applies to the toilet, thereby helping the user withstand repulsive force that is generated when the high-pressure gas is discharged. - With reference to
FIG. 4 , a description will be made of the operation of thetoilet plunger 100 of this embodiment. - When the drain of the toil is clogged, the
insert 150 is brought into contact with the opening of the drain of thetoilet bowl 10. Thegas container 110 is moved downwards by rotating thecover 140 in one direction, so that theclosing plate 114 of thegas container 110 is punctured by thepuncture pin 130, which is seated in the puncture pin-receivingportion 124. - When the
closing plate 114 is torn, high-pressure gas is discharged from thegas container 110 through the through-passage 132, passes through thepassage 125 and theinsert 150, and is then discharged into the drain. - Here, a portion of the high-pressure gas that is discharged through the puncture of the
closing plate 114 is discharged into thepassage 125 through thesafety passages 126 in order to adjust the pressure inside theplunger 100. - When the high-pressure gas that has been stored is used, the user can separate the
cover 140 from thebody 120 by rotating it in the other direction and replace thegas container 110 with a new one, which is then ready to be used. - As set forth above, high-pressure gas is instantaneously discharged toward a clogged drain by puncturing one portion of the gas container, in which the high-pressure gas is contained, using the puncture pin, and the insert, which is intended to be inserted into the drain, is bent at a predetermined angle, so that high-pressure gas can be properly discharged toward the drain, thereby easily unclogging the drain.
- Furthermore, the body is coupled to the cover using a screw. Consequently, a gas container can be easily replaced when it is exhausted, and thus the toilet plunger can be reused.
