Proposed is a water jet plunger. The water jet plunger is provided with a body part having a tubular shape and including a discharge port that can be opened and closed at one end thereof and a pressurizing part disposed inside the body part and capable of reciprocating in the longitudinal direction of the body part, so that as the pressurizing part presses the inside of the body part where water is accommodated, the discharge port provided at one end of the body part is opened by pressure generated by the pressurization of the pressurizing part to spray the water with an instantaneous to remove foreign matter blocking a pipe of a toilet.

TECHNICAL FIELD

The present disclosure relates to a waterjet plunger and, more particularly, to a waterjet plunger that sprays water with instant pressure to remove foreign matter in a toilet.

BACKGROUND ART

Due to urbanization, people's living environment has changed rapidly in recent years, and the residential environment has changed dramatically compared to the past. In particular, a toilet room where hygiene should be the most emphasized in real life has transformed from a dirty and stinky traditional latrine into a place with a high level of cleanliness equipped with sanitary wares including a hygienic and clean toilet.

In general, toilets allow users to urinate or defecate in a sitting position. In a toilet, a certain amount of water is stored in the cistern, a small tank, and after a user urinates or defecates, the water in the tank is flushed, so that the urine or feces can be discharged into a septic tank. A toilet utilizes an “S” shaped siphon structure to prevent the water from flowing up from a sewage pipe. However, due to the “S” shaped structure, toilet paper or foreign matter block the pipe, resulting in a clogged toilet.

As an example of an effort to address these issues, Korean Patent Application Publication No. 10-2007-0009055 (hereinafter referred to as “cited invention”) discloses a configuration for solving the clogging of a drain or toilet by making a close-fitting member come into close contact with an inlet of the drain to accommodate the inlet of the drain, so that the pressure inside a casing is discharged by means of a piston to a discharge pipe to remove foreign matter clogging the drain.

Still, the cited invention has a problem that, as the pressure inside the casing is constantly discharged through the discharge pipe by means of the piston, when the area of blockage is wide or the size of the foreign matter blocking the pipe is large, unclogging may not be easily performed. In order to solve this problem, a means to discharge a large force at once and unclog the toilet is needed.

DISCLOSURE

Technical Problem

Accordingly, the present disclosure has been made keeping in mind the above problems occurring in the related art, and the present disclosure is intended to propose a waterjet plunger provided with a body part having a tubular shape and including a discharge port that can be opened and closed at one end thereof and a pressurizing part disposed inside the body part and capable of reciprocating in the longitudinal direction of the body part, so that as the pressurizing part presses the inside of the body part where water is accommodated, the discharge port provided at one end of the body part is opened by pressure to solve the clogging of a toilet by spraying the water with an instantaneous pressure rather than releasing the pressure constantly.

Technical Solution

In order to achieve the above objectives, according to an embodiment of the present disclosure, there is provided a waterjet plunger, including: a body part configured to have a tubular shape; and a pressurizing part disposed inside the body part, and configured to have a piston capable of reciprocating in a longitudinal direction of the body part at a first end thereof, wherein the body part may include a discharge port configured to control water injected from an outside on a first end side thereof, wherein the discharge port may be opened by pressure generated as water accommodated in the body part is pressed by the pressurizing part to discharge the water toward a first end of the body part.

In addition, the body part may further include: a siphon insertion port provided at the first end thereof at an obtuse angle with the body part, and configured to have a size corresponding to an inlet of a siphon tube of a toilet so as to be insertable into the siphon tube of the toilet.

In addition, the discharge port may be coupled with an opening/closing port provided on a first end side of an inner side of the body part by magnetic force to prevent water from being discharged to the outside, and the discharge port may be opened as the opening/closing port is pressed toward the discharge port by the pressure generated from the pressurizing part.

In addition, the discharge port may be provided with a discharge hole therein and formed in a plate shape with an edge corresponding to the inner side of the body part, wherein the discharge hole may be provided with a ring-shaped flange having magnetic properties on an inner periphery thereof so as to be coupled with the opening/closing port by a magnetic force, and a connecting port coupled to a hinge, provided on a surface of the discharge port in a direction in which water is discharged, may be connected to a surface of the opening/closing port so that the discharge hole and the opening/closing port are coupled by the magnetic force at a certain position.

In addition, the discharge port may be opened and closed as the opening/closing port and a point inside the body part are coupled by means of an elastic member.

In addition, the body part may further include: a water injection inlet formed to be inclined upward at a second end thereof for injecting water into the body part from the outside.

In addition, the pressurizing part may have a hollow shape, and the piston may include: a longitudinal hole at a position corresponding to an inner space of the pressurizing part, and piston valves provided on a surface in a direction of the discharge port, and configured to be opened and closed so that water introduced into the pressurizing part from the outside moves in the direction of the discharge port.

In addition, the pressurizing part may be provided with a water inflow inlet in an upper direction adjacent to the piston, wherein the water inflow inlet may allow water introduced into the body part and accommodated above the piston to flow into the inner space of the pressurizing part.

In addition, the pressurizing part may further include: a water injection inlet provided at a second end thereof to allow water to flow into an inside of the pressurizing part.

Advantageous Effects

According to the present disclosure, it is possible to remove foreign matter blocking a pipe of a toilet since an opening/closing port is provided at one end of a body part and, in a state in which water flowing into the body part from the outside is accommodated, a pressurizing part disposed inside the body part presses the body part where the water is accommodated, so that the opening/closing port provided at one end of the body part is opened and the water is sprayed with an instantaneous pressure.

BEST MODE

An objective of the present disclosure is to provide a water jet plunger configured to have: a body part having a tubular shape and including a discharge port that can be opened and closed at one end thereof, and a pressurizing part disposed inside the body part and capable of reciprocating in the longitudinal direction of the body part, so that as the pressurizing part presses the inside of the body part where water is accommodated, the discharge port provided at one end of the body part is opened by pressure generated by the pressurization of the pressurizing part to spray the water with an instantaneous to remove foreign matter blocking a pipe of a toilet.

The scope of the present disclosure is not limited to the embodiments described below, and various modifications may be made by those skilled in the art within the scope of not departing from the technical gist of the present disclosure.

As shown inFIGS.1to17, a waterjet plunger10of the present disclosure may include: a body part100in the shape of a hollow tube; and a pressurizing part200having one end thereof provided inside the body part100and reciprocating in the longitudinal direction of the body part100.

As shown inFIGS.2to6, the body part100may be provided with a discharge port120for controlling water injected from the outside at one end side thereof. In a state in which the water injected from the outside is accommodated in the body part100, the opening/closing port130is opened by the pressure generated as the pressurizing part200is moved toward a discharge port120, and through the discharge port120, the accommodated water may be discharged with an instantaneous pressure in the direction of one end of the body part100.

As shown inFIGS.2to3, the body part100may be formed in the shape of a hollow tube. At this time, the body part100may be formed so that the shape of the inside of the body part100and the shape of a piston230correspond in order for the piston230provided in the pressurizing part200is inserted into the body part100and moved in the longitudinal direction of the body part100.

At this time, the water accommodated in the body part100may be discharged to the outside by pressure generated as the pressurizing part200moves from the upper side of the body part100to the lower side the body part100in the body part100. It is preferable that the inner shape of the body part100is cylindrical in order to smoothly discharge the accommodated water to the outside with instantaneous pressure.

In addition, as shown inFIGS.1to3, the body part100may have a water injection inlet110to receive water from the outside into the inner space thereof, and the water injection inlet110may be formed at the other end of the body part100so as to be inclined upward while communicating with the body part100.

As for the water injection inlet110, the shape for injecting water into the body part100from the outside and the method of injecting water into the body part100from the outside are not limited. However, the water injection inlet110is preferably formed to be inclined upward while communicating with the body part100, or to have a longitudinal cross section formed in a “.” shape in order to facilitate the role of the water injection inlet110to inject water into the body part100from the outside.

In addition, as shown inFIG.6, the water injection inlet110may communicate with the body part100at a position lower than the height when the piston230of the pressurizing part200disposed in the body part100is raised to the maximum in the body part100. Due to this, when water is accommodated in the body part100, the pressure delivered from the pressurizing part200may be smoothly transferred to the accommodated water by means of the piston230.

The water accommodated inside the body part100does not flow into the body part100only through the water injection inlet110, and the method of introducing water from the outside into the body part100may not be limited.

At this time, when the water injection inlet110is not provided in the body part100, water may be introduced into the body part100through the other end of the pressurizing part200having an empty interior, details of which will be described in detail through another example to be described later.

As shown inFIGS.1to15, the body part100may have a siphon insertion port140at one end thereof that forms an obtuse angle with the body part100. The siphon insertion port140is formed in a size corresponding to the inlet of a siphon tube21of a toilet20so as to be insertable into the inlet of the siphon tube21of the toilet20.

At this time, as shown inFIGS.2to3and inFIGS.16to17, since the siphon insertion port140is formed at an obtuse angle and is formed to be inserted into the inlet of the siphon tube21of the toilet20, when the water accommodated in the body part100is pressed by the pressurizing part200while the siphon insertion port140is inserted into the inlet of the siphon tube21of the toilet20, the water accommodated in the body part100is discharged with an instantaneous pressure toward the siphon tube21of the toilet20, delivering powerful pressure and water to foreign matter23clogging the siphon tube21.

At this time, as the toilet20has a shape in which the bowl gradually narrows toward the starting point of the siphon tube21, correspondingly, the siphon insertion port140may be formed in a shape in which an area becomes narrower toward one end.

In addition, as shown inFIGS.3and5, the body part100may be provided with the discharge port120at one end thereof formed in a plate shape having an edge corresponding to the inner side of the body part100.

The discharge port120may be opened or closed by the coupling of a discharge hole121formed therein and the opening/closing port130. When the discharge port120is closed, water injected into the body part100may be accommodated in the body part100, whereas when the discharge port120is opened, water accommodated in the body part100may be discharged in one direction of the body part100.

As shown inFIG.5, the discharge port120may be disposed in an area adjacent to the siphon insertion port140formed in the body part100. A hinge123is formed on one side of the discharge port120in the direction in which the water accommodated inside the body part100is discharged. As one end of a connecting port124is coupled to the hinge123and the other end of the connecting port124is coupled to one surface of the opening/closing port130, the opening/closing port130rotates at a certain position.

At this time, the discharge hole121may be provided with a flange122having magnetic properties on the inner periphery thereof, and the opening/closing port130may be formed of a material having magnetic properties. Accordingly, as the opening/closing port130is coupled with the flange122provided on the inner periphery of the discharge hole121by magnetic force, the discharge hole121may be closed or opened. For example, when pressure is delivered from the pressurizing part200, the discharge hole120is opened as the coupling between the opening/closing port130and the discharge hole121by magnetic force is released by the pressure.

At this time, as the water accommodated in the body part100is sprayed by pressure, the water may be discharged to one end of the siphon insertion port140with an instantaneous pressure.

As another example, as shown inFIGS.13to14, the discharge hole120may be opened and closed as the opening/closing port130and a point inside the body part100are coupled by an elastic member150. For example, the opening/closing port130may be provided with a first spring piece131on one side in the piston direction of the opening/closing port130, and a second spring piece132may be formed at a point inside the body part100facing the first spring piece131, so that the first spring piece131and the second spring piece132may be connected by the elastic member150.

Due to this, the discharge hole120maintains a closed state by the elastic member150at normal times, and when a user presses the pressurizing part200in the direction of the discharge port120while water is accommodated in the body part100, the water accommodated inside the body part100is sprayed by pressure, and the opening/closing port130is pressed by the water and instantaneous pressure and the discharge hole120is opened, so that the water may be discharged to one end of the siphon insertion port140.

As shown inFIGS.1to4, the pressurizing part200may be provided with a handle210at the other end thereof, and one end thereof may include the piston230disposed inside the body part100. At this time, at least one piston O-ring231for sealing the inside of the body part100may be provided on the outer periphery of the piston230.

In addition, the pressurizing part200may be provided with a stopper260at one end thereof, in an area adjacent to the handle210. Because of the stopper260, in pressing the pressurizing part200toward the body part100, it is possible to prevent the pressurizing part200from being inserted into the body part100beyond a certain length.

As another example, as shown inFIGS.7to12, the pressurizing part200may further include piston valves240A and240B on the piston230provided at one end thereof.

At this time, as shown inFIGS.7to9, the piston230may have a hole communicating with one surface in the direction of the discharge port120and the pressurizing part200. The hole communicating with the pressurizing part200is formed to be opened and closed by the piston valve240A composed of a piston valve hinge242and a piston valve opening/closing plate241.

The hole may be normally kept open, but when the piston230moves in the direction of the discharge port120of the body part100when the pressurizing part200receives force from the outside, the hole communicating with the pressurizing part200may be closed.

At this time, in the pressurizing part200, a water inflow inlet250may be formed at a point adjacent to the upward direction of the piston230to allow water accommodated in the body part100to flow into the pressurizing part200.

Thus, when water is accommodated inside the body part100and above the piston230, the water moved into the pressurizing part200through the water inflow inlet250may pass through the internal space of the piston230and may be moved in the direction of the discharge port120of the body part100as the piston valve240A is opened.

As such, in introducing water into the body part100, water may flow into the body part100regardless of the position of the piston230of the pressurizing part200.

In addition, as another example, as shown inFIGS.10,11, and15, the pressurizing part200may be formed in a tubular shape with an empty inside, and may be provided with a water injection inlet211at the other end thereof. At this time, the piston230may have a hole formed on one surface in the direction of the discharge port120and that communicates with the pressurizing part200. The hole may be provided with the piston valve240B composed of a piston valve cap243and a cap support244.

Due to this, when a user injects water through the water injection inlet211formed at the other end of the pressurizing part200, the water may move toward the discharge port120of the body part100through the inside of the pressurizing part200and through the piston valve240B without passing through the body part100.

At this time, in the piston valve240B, the piston cap243is positioned on the cap support244located therebelow due to gravity, so that the water injected through the water injection inlet211may move toward the discharge port120.

At this time, when the user presses the pressurizing part200to discharge water, the piston valve cap243comes into contact with the water, and accordingly, the hole formed in the piston is closed by pressure. Therefore, in using the water jet plunger10, water does not flow backward in the direction of the pressurizing part200.
