Description

[Technical field]

[0001] The present invention relates to a pipe clogging treatment device, and more particularly to a pipe clogging treatment device that applies air pressure to a pipe whose inside is clogged with a foreign object to treat the clogged pipe. [Background technology]

[0002] In general, when a toilet or pipe is clogged with a foreign object, the foreign object cannot be removed with normal water pressure. In this case, a tool such as a drain cleaner or a plunger must be used. However, such a drain cleaner or plunger has a problem that it is difficult to use when the clog is caused by a curved pipe or a pipe whose size does not match the end of the tool. In addition, when the size of the pipe and the tool do not match, pressure leaks and the pressure is not easily transmitted to the foreign object.

[0003] As a prior art document to solve the problems of such conventional pipe clog treatment devices, Korean Patent Publication No. 10-2020-0077318 discloses a stick drain cleaner that dissolves and removes foreign objects when inserted into a drainage pipe clogged with foreign objects.

[0004] However, such conventional techniques have problems in that the foreign matter cannot be dissolved by chemicals, or is difficult to remove when it has accumulated in large quantities or when it has accumulated deep in the pipes. Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been devised to solve the problems of the prior art as described above, and aims to seal the inlet of a pipe clogged with foreign matter, and then apply air pressure to the clogged pipe to effectively remove the foreign matter. [Means for solving the problem]

[0006] A pipe clog treatment device according to a preferred embodiment of the present invention includes a main body accommodating an accumulator capable of accumulating high-pressure air capable of removing foreign objects clogging a pipe; an air compressor connected to one side of the main body and accumulating air inside the main body to increase air pressure and accumulated amount; a pipe inlet connected to an end of the main body and expanding to a preset volume and shape when the accumulated air in the main body is injected, and deforming to correspond to the inlet shape of the clogged pipe when pressed against an inlet of the clogged pipe to seal the inside and outside of the clogged pipe, and expanding to correspond to the size and shape of the inside of the pipe when introduced into the inlet of the clogged pipe and sealing the inside and outside of the pipe by being pressed against an inner peripheral surface of the pipe; and an air pressure discharge unit provided inside the pipe inlet, connected to the main body, and bendable. The air pressure discharge unit discharges high-pressure air accumulated inside the main body into the inside of a clogged pipe whose inlet is sealed by the pipe lead-in unit, thereby effectively removing foreign matter inside the clogged pipe. Effect of the Invention

[0007] By solving the above problem, the present invention has the effect of making it possible to remove foreign matter blocking a pipe by passing high-pressure air through the pipe.

[0008] In addition, the present invention has the effect of expanding the volume of the pipe inlet portion when it is inserted into the inlet of the pipe, thereby making it tightly attached to the inner surface of the pipe, thereby making it possible to seal the inside of the pipe regardless of the diameter of the pipe.

[0009] In addition, the piping retraction section of the present invention has the effect of allowing the piping retraction section, which is molded from a material having elasticity, and the air pressure discharge section, which is molded into a bellows hose structure, to be bent and easily retracted even in piping having a complex bent structure making it difficult to use tools such as a rubber cup, thereby enabling foreign matter to be removed.

[0010] In addition, even if the piping inlet part is not inserted into the piping, when the piping inlet part is expanded into a horn shape, the internal pressure is the same but the external pressure can be accommodated depending on the shape and curvature of the joint surface. Therefore, when the two parts are joined and pressure is applied, they can be tightly attached, and the air pressure discharged from the air pressure discharge part can be transmitted without being lost by any obstructing foreign objects.

[0011] Furthermore, the present invention has an effect of providing an accumulator, thereby enabling high air pressure to be generated even with a pump and an electric motor having a small capacity and output. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] The terms used in this specification will be briefly explained and the present invention will be specifically described.

[0014] The terms used in the present invention are currently selected as widely used general terms as possible while taking into consideration the functions of the present invention, but these may differ depending on the intentions or precedents of engineers in the field, the emergence of new technologies, etc. Therefore, the terms used in the present invention should be defined based on the meanings that the terms have and the overall content of the present invention, rather than simply the names of the terms.

[0015] Throughout the specification, when a part "comprises" a certain element, this means that it may further include other elements, not excluding other elements, unless specifically stated to the contrary.

[0016] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the accompanying drawings, in which: FIG. 1 is a block diagram of a semiconductor device according to an embodiment of the present invention;

[0017] The specific matters including the problems to be solved by the present invention, the means for solving the problems, and the effects of the present invention are included in the following embodiments and drawings. The advantages and features of the present invention, and the method for achieving them, should be clear by referring to the embodiments described in detail below together with the accompanying drawings.

[0018] The pipe clogging treatment device of the present invention will be described in detail below with reference to the accompanying drawings.

[0019] 1 to 11, the pipe clogging treatment device according to the first preferred embodiment of the present invention includes a body 100 accommodating an accumulator 110 capable of accumulating high-pressure air capable of removing foreign objects clogging a pipe, an air compressor 200 connected to one side of the body 100 and accumulating air inside the body 100 so that the air pressure inside the body 100 can be increased to a preset upper limit pressure, and an air compressor 200 connected to an end of the body 100 so that when air is injected into the body 100, the air compressor 200 has a preset volume and shape. The air pressure discharge part 400 includes a pipe inlet 300 which, when it is inflated to a predetermined size and shape and pressed against the outer wall or inlet of a clogged pipe, deforms to correspond to the shape of the outer wall or inlet of the clogged pipe to seal the inside and outside of the clogged pipe, and when it is introduced into the inlet of the clogged pipe, expands to correspond to the size and shape of the inside of the pipe and pressurizes against the inner peripheral surface of the pipe to seal the inside and outside of the pipe, and a bendable air pressure discharge part 400 which is provided inside the pipe inlet 300 and communicates with the main body 100. The air pressure discharge part 400 discharges high pressure air accumulated inside the main body 100 into the inside of the clogged pipe whose inlet is sealed by the pipe inlet 300, so that foreign objects inside the clogged pipe can be effectively removed.

[0020] First, the body 100 serves to fill the interior with air and maintain a high air pressure. More specifically, the main body 100 includes an accumulator 110 provided inside the main body 100, an injection valve 120 that enables a portion where the piping inlet 300 and the main body 100 are connected to be opened and closed, a discharge valve 130 that enables a portion where the air pressure discharge part 400 and the main body 100 are connected to be opened and closed, a valve partition member 140 that separates the injection valve 120 and the discharge valve 130 from the accumulator 110, a body partition member 150 that is provided at an end of the main body 100 and separates the accumulator 110 from the injection valve 120 and the discharge valve 130, a communication part 160 that is connected in a manner to be joined to the body partition member 150, a connecting bracket 170 that covers the communication part 160 and is fastened to an end of the main body 100, and a handle 180 provided on one side of the main body 100.

[0021] The accumulator 110 contains a compressible fluid and is made of an elastic material, so that it contracts when pressure is applied and returns to its original state when pressure is released. That is, when air is filled in the body 100 and pressure rises, the accumulator 110 contracts and the internal pressure increases. At this time, the accumulator 110 is compressed in one direction, so that the air filled in the body 100 is compressed in the opposite direction to the compression of the accumulator 110. The accumulator 110 includes a filling part 111 provided at a portion where an end of the accumulator 110 abuts against the body 100, and a pressure gauge 112 that indicates the internal pressure of the body 100. The filling part 111 allows the compressible fluid to be filled in the accumulator 110, so that the air pressure held in the body 100 can be adjusted. In addition, the accumulator 110 allows the internal air pressure of the main body 100 to be maintained at a high pressure so that it can be effectively discharged, and allows foreign objects in clogged piping to be easily removed.

[0022] Also, the injector valve 120 serves to inject the air inside the main body 100 into the piping inlet 300. As an example, the injector valve 120 includes an injector plug 121 that blocks an inlet through which the air inside the main body 100 is injected into the piping inlet 300, an injector valve rod 122 connected to the injector plug 121, an injector valve operation part 123 connected to an end of the injector valve rod 122, and a first elastic pressurizing part 124 that pressurizes the injector valve operation part 123. First, the injector plug 121 is provided in a plug shape that covers a part where the air inside the main body 100 is communicated with the piping inlet 300, and has a hole that allows the air to pass through. In addition, the injection plug 121 includes a first sliding member 1211 that protrudes from one surface of the injection plug 121 and is bent downward, and a first spring 1212 that presses the upper part of the injection plug 121. The first sliding member 1211 is provided in a shape that is pointed downward and has a slope. In addition, the first spring 1212 prevents the hole of the injection plug 121 from facing the hole of the piping inlet 300 of the communication part 160 due to pressure, so that the air inside the main body 100 does not flow to the piping inlet 300. In addition, the injection valve rod 122 is provided in a rod shape provided in the length direction of the main body 100 and is housed inside the main body 100. In addition, the injection part valve rod 122 includes a second sliding member 1221 having a pointed shape toward the first sliding member 1211 and a slope that comes into contact with the slope of the first sliding member 1211. In addition, the injection part valve operation part 123 is inserted from the outer circumferential surface of the main body part 100 and connected to an end part of the injection part valve rod 122. At this time, the injection part valve operation part 123 includes a first seating groove part 1231 into which the injection part valve rod 122 can be inserted and seated, and a first hook part 1232 that allows the injection part valve operation part 123 to be temporarily fixed to the main body part 100.The injection part valve operation part 123 is provided in an "U" shape having a minimum length so that it can be moved back and forth in the length direction of the body part 100, and a part of the upper part is inserted into the body part 100 in such a manner that the upper part is disposed at the lower inside of the body part 100 and the lower part is disposed at the lower outside of the body part 100. The first hook part 1232 is provided in a form protruding from one side of the injection part valve operation 123 toward the outer circumferential surface of the body part 100, and when it is engaged with a locking neck provided on the body part 100, the injection part valve operation part 123 can be temporarily fixed. In addition, the first elastic pressurizing part 124 is provided between the outer circumferential surface of the main body 100 and the injection part valve operating part 123, and is composed of two coil springs, and presses the injection part valve operating part 123 downward to prevent the injection part valve operating part 123 from coming off, and the bottom surface of the "U" shaped upper part of the injection part valve operating part 123 is tightly attached to the inner bottom surface of the lower part of the main body 100, thereby preventing air leakage. That is, when the injection part valve operating part 123 is pressed forward, the injection part valve rod 122 is moved, and the second sliding member 1221 pushes up the first sliding member 1211, so that the injection part plug 121 can be moved upward. In addition, when the injection port plug 121 is moved upward, the hole of the communication portion 160 and the hole of the injection port plug 121 face each other, so that the passage is opened and air inside the main body portion 100 can be injected into the piping inlet portion 300.

[0023] Also, the discharge valve 130 serves to allow air inside the main body 100 to be discharged through the pneumatic discharge part 400. As an example, the discharge valve 130 includes a discharge plug 131 for closing an inlet through which the air inside the main body 100 is discharged to the pneumatic discharge part 400, a discharge valve rod 132 connected to the discharge plug 131, a discharge valve operation part 133 connected to an end of the discharge valve rod 132, a second elastic pressurizing part 134 for pressurizing the discharge valve operation part 133, and a discharge trigger 135 connected to the discharge valve operation part 133. First, the discharge plug 131 is provided in a plug shape covering a part where the air inside the main body 100 is communicated with the pneumatic discharge part 400, and has a hole through which air can pass. The outlet plug 131 includes a third sliding member 1311 that protrudes from one surface of the outlet plug 131 and is bent downward, and a second spring 1312 that presses the upper part of the outlet plug 131. The third sliding member 1311 is provided in a pointed shape toward the bottom and has a slope. The second spring 1312 prevents the hole of the outlet plug 131 from facing the hole of the air pressure outlet 400 of the communication part 160 due to pressure, so that the air inside the main body 100 is not discharged through the air pressure outlet 400. The outlet valve rod 132 is rod-shaped and arranged in the length direction of the main body 100, and is arranged parallel to the inlet valve rod 122. In addition, the discharge valve rod 132 includes a fourth sliding member 1321 that is sharpened toward the third sliding member 1311 and has a slope that comes into contact with the slope of the third sliding member 1311. In addition, the discharge valve operation part 133 is inserted from the outer circumferential surface of the body part 100 and connected to an end of the discharge valve rod 132. At this time, the discharge valve operation part 133 may include a second seating groove part 1331 into which the discharge valve rod 132 can be inserted and seated, and a second hook part 1332 that allows the discharge valve operation part 133 to be temporarily fixed to the body part 100.The discharge valve operating part 133 is provided in an "U" shape having a minimum length so that it can be reciprocated in the length direction of the body part 100, and an upper part is inserted into the body part 100 in such a manner that an upper part is disposed at the lower inside of the body part 100 and a lower part is disposed at the lower outside of the body part 100. The second elastic pressurizing part 134 is provided between the outer circumferential surface of the body part 100 and the discharge valve operating part 133, and is composed of two springs, and presses the discharge valve operating part 133 downward to prevent the discharge valve operating part 133 from coming off, and the upper bottom surface of the "U" shape is in close contact with the inner side surface of the lower part of the body part 100 to prevent air leakage. Referring to FIG. 8, when one side of the discharge trigger 135 is pulled, the other side presses the discharge valve operating part 133 forward. That is, when the discharge part trigger 135 is pulled, the discharge part valve operation part 133 is pressed forward, the discharge part valve rod 132 is moved, and the fourth sliding member 1321 pushes up the third sliding member 1311, so that the discharge part plug 131 can be moved upward. Also, when the discharge part plug 131 is moved upward, a hole provided in the discharge part plug 131 faces a hole of the air pressure discharge part 400 provided in the communication part 160 to secure a passage, so that the air inside the main body part 100 can be discharged through the air pressure discharge part 400. Therefore, the discharge part valve 130 is arranged in parallel with the injection part valve 120, so that the flow of air through the air pressure discharge part 400 can be controlled. In addition, the inlet valve 120 and the outlet valve 130 allow the air inside the main body 100 to be selectively connected to the piping inlet 300 and the air pressure outlet 400, respectively, so that the flow of air can be controlled.

[0024] Also, the valve partition member 140 serves to isolate the inlet valve 120 and the outlet valve 130, which are inserted into the lower part of the main body 100 as shown in the enlarged views of Figs. 2 and 8, from interference during the expansion and contraction of the accumulator 110. As an example, the valve partition member 140 is provided in the length direction of the main body 100 and is formed in a hollow shape. Also, the valve partition member 140 is disposed to be in close contact with the lower part of the inner circumferential surface of the main body 100. Also, the valve partition member 140 allows the inlet valve rod 122 and the outlet valve rod 132 to be housed in the hollow part. Also, the valve partition member 140 has holes in its lower part so that the upper parts of the inlet valve operating part 123 and the outlet valve operating part 133, which are inserted and coupled from the outer circumferential surface of the main body 100, can be inserted therein. That is, when the injector valve operating part 123 and the discharge part valve operating part 133 are pressurized by the first elastic pressurizing part 124 and the second elastic pressurizing part 134, the "U" shaped upper bottom surface of the discharge part valve operating part 133 and the injector valve operating part 123 can be tightly attached to the lower part of the inner peripheral surface of the main body part 100. At this time, when the injector valve operating part 121 is opened and the piping lead-in part 300 is expanded as shown in Fig. 11, as shown in the enlarged view of Fig. 11, when the injector valve operating part 123 is pressed upward to the upper main body part 100, the spring of the first elastic pressurizing part 124 is contracted and the "U" shaped upper bottom surface of the injector valve operating part 123 and the lower bottom surface of the main body part 100 are separated from each other, so that the air injected into the piping lead-in part 300 can be discharged to the outside.

[0025] 6 and 8, the body partition member 150 is provided at an end of the body 100 and contacts the accumulator 110 to prevent the accumulator 110 from being removed to the outside. A plurality of holes are formed in the body partition member 150 to prevent interference with the operation of the inlet valve rod 122 and the outlet valve rod 132 and the movement of air. A step is formed on the edge of the body partition member 150 to allow the communication part 160 and the body 100 to be easily seated.

[0026] Moreover, the central portion of the communication section 160 has two vertical sides, one side being provided between the injection section plug 121 and the discharge section plug 131 and the piping lead-in section 300 and the air pressure discharge section 400, and the other side being provided between the injection section plug 121 and the discharge section plug 131 and the first sliding member 1211 and the third sliding member 1311. That is, the injection section plug 121 and the discharge section plug 131 are provided between both sides (sides different from one side) of the central portion of the communication section 160 provided as described above, and move up and down by sliding while lightly contacting both sides. 8 to 11, holes communicating with the piping inlet 300 and the air pressure outlet 400 are formed on one side of the communication part 160, and vertical grooves are formed on the other side so that the first sliding member 1211 and the third sliding member 1311 can move up and down, as shown in the enlarged view of FIG. 8, and the inlet plug 121 and the outlet plug 131 can move up and down between the one side and the other side to control the flow of air. That is, air inside the body 100 passes through the vertical grooves through which the first sliding member 1211 and the third sliding member 1311 move, and passes through the holes of the inlet plug 121 and the outlet plug 131 and the corresponding holes of the communication part 160, and can be injected into the piping inlet 300 or discharged through the air pressure outlet 400. More specifically, the first sliding member 1211 and the third sliding member 1311 can be moved upward by the second sliding member 1221 and the fourth sliding member 1321 moving toward the communicating part 160. At this time, when the holes of the inlet plug 121 and the outlet plug 131 are aligned with the corresponding holes of the communicating part 160, air is discharged, and when they are not aligned with the corresponding holes of the communicating part 160, the discharge of air is blocked. In addition, when the holes of the inlet plug 121 and the outlet plug 131 are not aligned with the corresponding holes of the communicating part 160, the air pressure of the main body 100 pressurizes the inlet plug 121 and the outlet plug 131, so that the inlet plug 121 and the outlet plug 131 are tightly attached to one side of the communicating part 160 and sealed, thereby blocking the discharge of air.In the above context, when it is desired to prevent backflow of the high pressure air injected into the piping injection part 300 or discharged into the pneumatic discharge part 400, if the holes of the injection part plug 121 and the discharge part plug 1 are not aligned with the corresponding holes of the communication part 160, the high pressure air in the piping injection part 300 and the pneumatic discharge part 400 pressurizes the injection part plug 121 and the discharge part plug 131, but the other surface (the surface with the groove) is tightly sealed and prevents backflow. In this case, if there is no other surface, the injection part plug 121 and the discharge part plug 131 cannot be tightly sealed and cannot prevent backflow, so the communication part 160 needs to be provided on both sides (one side and the other side).

[0027] In addition, the connecting bracket 170 is provided in the form of a hollow cylinder to surround the body partition member 150 and the communication part 160, and is fastened to an end of the body part 100 so that the body partition member 150 and the communication part 160 are firmly fixed and sealed. In addition, the connecting bracket 170 is provided so that an end of the connecting bracket 170 engages with the piping inlet part 300, as shown in the enlarged view of Fig. 8, so that the communication part 160 to which the piping inlet part 300 is fixed and the body partition member 150 can be fastened to an end of the body part 100.

[0028] Next, the air compressor 200 is connected to one side of the main body 100 and serves to fill the inside of the main body 100 with air. As an example, the air compressor 200 is electrically operated and generates power by a power supply system (not shown) provided on one side to inject outside air into the main body 100. The air compressor 200 includes a one-way valve 210 provided on an inlet side where air is injected from the air compressor 200 into the main body 100, and a pressure limit switch 220 linked with the pressure gauge 112 to control the operation of the air compressor to stop when the internal pressure of the main body reaches a preset upper limit pressure. The one-way valve 210 is opened when air pressure is applied from the air compressor 200 to the main body 100, allowing air to be injected into the main body 100. On the other hand, the one-way valve 210 is not opened when air pressure is applied from the main body 100 to the air compressor 200, thereby allowing the air pressure inside the main body 100 to be maintained.

[0029] In addition, the pressure limit switch 220 stops the operation of the air compressor 200 and interrupts the inflow of air into the main body 100 when the pressure measured by the pressure gauge 112 reaches a preset upper limit pressure, and applies the operation of the air compressor 200 and the inflow of air when the pressure in the main body 100 does not reach the preset upper limit pressure.

[0030] Next, the pipe lead-in part 300 is made of an elastic material and can be flexibly bent, so that it can be easily led into the inside of a curved pipe. As an example, the pipe lead-in part 300 includes an outer tube 310 made of an elastic and flexible material and hollow, and an expansion limit pocket 320 made of a flexible non-elastic material and connected to the main body part 100, which is accommodated between the outer peripheral surface and the inner peripheral surface of the outer tube 310. When air is injected from inside the main body part 100, the expansion limit pocket 320 expands in a horn shape as shown in FIG. 16. The outer tube 310 is inflated together with the expansion limit pocket 320, and can be brought into close contact with the inner peripheral surface of clogged pipes of various sizes and shapes, so that the entrance of the clogged pipe is sealed. More specifically, the external tube 310 is provided in a hollow cylinder shape, and the air pressure discharge part 400 can be accommodated in the hollow part. The external tube 310 has an accommodation space between its inner and outer circumferential surfaces. The expansion limit pocket 320 is provided in the accommodation space between its inner and outer circumferential surfaces. The expansion limit pocket 320 is pressed into the interior of the external tube 310 in a parachute shape with a number of creases, and when air is injected from the interior of the body part 100, the expansion limit pocket 320 is expanded to a shape within a preset volume range, thereby preventing the external tube 310 from expanding beyond a limit value, and allowing the pipe lead-in part 300 to be tightly attached to the clogged pipe inlet, thereby preventing plastic deformation of the external tube 310. As an example, the expansion limit pocket 320 may be expanded to a horn shape with one end having a larger diameter than the other end. That is, the expansion limit pocket 320 does not expand into a round shape when air is injected into it like a normal balloon, but expands into a shape with a larger diameter at the end as shown in Fig. 4. Also, the expansion limit pocket 320 has a limit to its expandable volume since it is made of an inelastic material that maintains airtightness, and therefore the outer tube 310 that expands together with the expansion limit pocket 320 does not expand beyond a preset volume range.In addition, when the pipe inlet 300 is introduced into the pipe, the external tube 310 has a tendency to expand into a horn shape due to the expansion limit pocket 320, but if the structure and size of the inside of the clogged pipe restricts it from expanding to the limit of the expansion limit pocket 320, it can be sealed by being tightly attached at the restricting point. As a result, the pressure of the air discharged from the air pressure discharge part 400 is completely transmitted to the inside of the pipe, and foreign objects can be easily removed. In addition, when treating a clogged pipe whose structure and size do not allow the pipe inlet 300 to enter the pipe, the external tube 310 is allowed to expand to its limit, and then it is brought into close contact with the outer wall or inlet of the clogged pipe, and the pipe inlet 300 is pressed (pressurized) so that it is deformed corresponding to the contact surface, and then high-pressure air is discharged from the air pressure discharge part 400, so that the pipe inlet 300 and the outer wall or inlet are tightly attached and sealed, and the high-pressure air does not leak and foreign objects can be more easily removed.

[0031] Next, the air pressure discharge part 400 is opened and closed by the operation of the discharge part valve 130, and serves to discharge the air inside the main body part 100. As an example, the air pressure discharge part 400 is a flow path formed from one end to the other end of the hollow part of the piping lead-in part 300, and allows air to be discharged from the end side of the air pressure discharge part 400. Also, referring to FIG. 12, the air pressure discharge part 400 is provided so that an air hose H can be connected to the end, allowing the use of air tools and air filling. As an example, the end side of the air pressure discharge part 400 is provided with an outlet 410 provided so that an air hose H can be connected to inject air into an air tacker, a soccer ball, a tire, etc. Therefore, air can be injected into an air tacker, a soccer ball, a tire, etc. using the air discharged from the air pressure discharge part 400.

[0032] That is, when the air compressor 200 injects air into the main body 100, the accumulator 110 can accumulate and hold high air pressure inside the main body 100. In addition, when the injector valve operation unit 123 is moved forward while the accumulator 110 is compressed by air pressure, the injector plug 121 is moved upward to connect the piping inlet 300 and the main body 100, and air can be injected into the piping inlet 300 to expand it. When the injector valve operation unit 123 is moved further backward while the expanded state of the piping inlet 300 is maintained, the discharge trigger 135 is pulled, and the discharge plug 131 is moved upward to connect the pneumatic discharge unit 400 and the main body 100, and the high pressure air held through the pneumatic discharge unit 400 can be discharged. At this time, if a part of the air inside the main body 100 is first injected into the piping inlet 300 and the air pressure is reduced or if the foreign object in the clogged piping is not removed at once, air is accumulated through the air compressor 200 so that the internal pressure of the main body 100 reaches the preset upper limit pressure, and the clogged piping can be treated with the upper limit pressure of the piping clog treatment device of the present invention. Then, when the discharge valve operation unit 133 is moved forward and the injection valve operation unit 123 is pressurized in the centrifugal direction of the main body 100 with the discharge valve 130 closed, a gap is formed between the inner circumferential surface of the main body 100 and the upper and lower surfaces of the injection valve operation unit 123, and the air that expanded the piping injection unit 300 can be discharged.

[0033] 13 to 16, the pipe clog disposal device according to the present invention discloses that the pipe inlet part 300 is tightly attached to a pipe having a small diameter, and the pipe inlet part 300 is bent and introduced into a pipe having a bent space in front of the inlet, and then expanded to remove foreign matter inside the pipe. Also, the air pressure discharge part 400 is provided inside the inner circumferential surface of the expansion limit pocket 320, and is provided with a bendable hose in a bellows shape, and can be introduced into a bent pipe, and is provided with a cover for blocking the inflow of foreign matter from the outside.

[0034] Hereinafter, a pipe clogging treatment device according to a second embodiment of the present invention will be described. This embodiment differs from the first embodiment in that the air compressor is installed in a manual pump type, and the explanation of the first embodiment is used for other overlapping configurations.

[0035] Referring to FIG. 17, the present invention includes a manual pump type air compressor 500 connected to the upper part of the main body 100. The air compressor 500 includes a one-way valve 510 provided at an inlet side where air is injected from the air compressor 500 into the main body 100, a circular cylinder 520 having an accommodation space therein, a piston 530 retracted into the cylinder 520, a piston rod 540 connected to the piston 530 and capable of protruding out of the cylinder 520, and a compressor handle 550 connected to an end of the piston rod 540. The one-way valve 510 allows the insides of the cylinder 520 and the main body 100 to communicate with each other, and is opened only when pressure is applied from the cylinder 520 to the main body 100. The inside of the cylinder 520 is sealed by the piston 530, and air can be compressed or expanded by the movement of the piston 530, and the air can be introduced into the cylinder 520. Also, when the user presses the compressor handle 550 inward of the cylinder 500, the piston 530 is transferred into the cylinder 520 to compress the air, and the air compressed by the piston 530 can be injected into the main body 100. That is, the air compressor 500 is operated by the user's strength to fill the air inside the main body 100 up to the upper limit pressure preset in the pressure gauge 112, and can stop pumping operation even if the pressure falls below the upper limit pressure, if necessary.

[0036] Hereinafter, a pipe clogging treatment device according to a third embodiment of the present invention will be described. This embodiment differs from the first embodiment in that a projectile is provided that is launched by the pressure of air discharged from the main body, and the explanation of the first embodiment is used for other overlapping configurations.

[0037] 18 to 20, the present invention includes a launcher 600 that can be installed between the main body 100 and the air pressure discharger 400, and a projectile S that can be mounted on the launcher 600. As an example, the launcher 600 can be connected to one side of the communication part 160. The launcher 600 is provided so that the projectile S, which is provided in a bullet-like shape, can be mounted on it. That is, the launcher 600 is provided in a hollow shape so that the projectile S can be mounted and temporarily fixed, and is fastened to a part from which air is discharged at an end side of the communication part 160. In addition, when the projectile S is mounted on the launcher 600, the piping inlet 300 is connected to the main body 100, or when the projectile S is pushed in reverse from the end of the piping inlet 300 with the piping inlet 300 fastened, the projectile S is positioned at the inlet side of the air pressure discharger 400. When the discharge unit trigger 135 is pulled to discharge air, the projectile S is launched by air pressure, and the air pressure discharge unit 400 can guide the launch direction of the projectile S. Thus, the launch pad 600 serves to load the projectile S, and the projectile S is launched at the same time as the high pressure air stored in the body unit 100 is discharged through the air pressure discharge unit 400, so that foreign objects blocking the piping can be removed.

[0038] In conclusion, the present invention is a pipe inlet made of a flexible rubber material having elasticity and stretchability and air, and even if the inlet of the clogged pipe is small or has an obstacle or is unbalanced so that the pipe inlet cannot be inserted, the pipe inlet can be expanded to the expansion limit line and pressed against the outer wall or inlet of the clogged pipe, so that the pipe inlet can be deformed to correspond to the shape of the outer wall or inlet of the pipe and sealed, so that the high-pressure air of the main body can be injected into the clogged pipe without leakage and foreign matter can be efficiently removed. In addition, the present invention is capable of expanding the volume of the pipe inlet when it is inserted into the inlet of the clogged pipe, and after it is sealed by being in close contact with the inner circumferential surface using the expansion force, the high-pressure air of the main body can be injected directly between the clogged part of the pipe and the pipe inlet, so that the clog in the pipe can be treated regardless of the diameter and shape of the pipe. In addition, even if the inlet of the clogged pipe is curved, the air pressure discharge part is configured in the form of a bellows hose, so that it can easily enter together with the pipe injection part, and foreign matter inside the curved pipe can be effectively treated. In addition, the present invention allows the piping inlet to be expanded by the high-pressure air of the main body, and then allows the air inside the main body to be recharged up to a preset upper limit pressure as necessary, and the recharged high-pressure air can be discharged again through the air pressure discharge part, thereby making it possible to more effectively remove foreign matter and to apply a main body with a smaller capacity. In addition, in the present invention, a cover device can be provided to prevent external foreign matter from entering the end of the air pressure discharge part 400 except when the air hose H is connected or when the projectile S is fired. In addition, the present invention has the effect of providing an accumulator, thereby enabling high-pressure air to be generated even with a pump and an electric motor with a small capacity and output.
