Description

Hose connecting module for fluid delivery and assembling method thereof

The present invention relates to a hose connection module for fluid transmission that can airtightly connect hoses used for fluid transmission and minimize flow path resistance.

In general, a hose is a tool used to transfer various fluids and is formed of a flexible material to be connected while being freely bent and deformed along the direction of connection or extension.

The hose provided to the water purifier is used to guide the flow of water in the water tank (or water pipe) through the filter until the water is discharged. At this time, the hose is connected to the filter or each pipe line using one or more hose connection modules.

The hose connection module is a structure provided to serve to change the connection direction of hoses, connect two hoses to each other, or connect a filter head and a hose.

The hose connection module is configured to be connected by inserting a connection pipe into a soft hose.

However, in the conventional structure for general hose connection as described above, the hose is often separated from the connection pipe by water pressure.

Accordingly, in the related art, coupling is improved by additionally providing a fastening aid (eg, fastening cap, fixing cap, cap, etc.) for gripping the connection portion between the hose and the connecting pipe. Regarding this, various forms such as Registered Patent No. 10-2223794, Registered Utility Model No. 20-0292833, Registered Utility Model No. 20-0321511, and Unexamined Utility Model No. 20-2013-0002819 are provided.

On the other hand, in the case of the prior art described above, the size of the outer diameter of the connecting pipe is determined in consideration of the inner diameter of the hose so that the connecting pipe can be inserted into the hose.

Of course, since leakage occurs during use of the product when the hose and the connection pipe are not accurately coupled, it is preferable to determine the size of the outer diameter of the connection pipe so that the connection pipe can be press-fitted to the hose.

However, if the outer diameter of the connecting pipe is excessively large, there is a problem in that the hose is torn during press-fitting into the hose. Therefore, it is preferable that the outer diameter and the inner diameter of the connecting pipe are determined in consideration of the strain rate of the hose.

Conventionally, the connection pipe is formed to a thickness sufficiently thick to prevent damage such as bending deformation or breakage when press fitting into a hose. Accordingly, the inner diameter of the connecting pipe is inevitably smaller than the inner diameter of the hose, and the connecting pipe protrudes into the inside of the hose by a difference in inner diameter between the connecting pipe and the hose, thereby inevitably acting as a part obstructing the flow.

That is, while flowing along the hose by the protruding height of the connection pipe, the fluid flowing into the connection pipe is subjected to flow resistance, resulting in a decrease in overall flow rate and a decrease in flow rate.

In particular, in the prior art, the end of the connection pipe is formed inclined so as to be smoothly inserted into the hose.

However, unlike the inclined structure of the connecting pipe, since the inner circumferential surface of the hose is formed in a non-sloping structure, a gap is generated between the end of the connecting pipe and the inner circumferential surface of the hose, and the flow resistance of the fluid is more severe due to this gap. There was a problem.

Of course, in recent years, many efforts and studies have been made to reduce the flow resistance due to the gap or the difference between the inner diameters of the connecting pipe and the hose by maximizing the inner and outer diameters of the connecting pipe.

For example, by heating the hose to increase its ductility, it is also possible to prevent tearing when the connecting pipe is press-fitted.

However, the method of heating the hose may cause permanent deformation of the hose. That is, since a conventional hose is mainly formed of a thermosetting resin, as it is cured by heat applied to the hose and loses ductility, a gap is generated at a close contact between the hose and the connecting pipe, resulting in leakage.

In addition, since the structure for uniformly heating the hose to a constant temperature is inevitably complicated, it is difficult to apply it in practice.

In addition, as described above, in the process of press-fitting the connection pipe into the hose, when the press-fitting direction of the connection pipe does not exactly match the axial direction of the hose and is tilted (bent or bent), the end of the connection pipe is caught in the hose. As a result, the hooked portion is stretched or torn, resulting in a problem in that it cannot be accurately coupled.

Registered Patent No. 10-2223794 Registered Utility Model No. 20-0292833 Registered Utility Model No. 20-0321511 Public utility model No. 20-2013-0002819

The present invention has been made to solve various problems according to the prior art described above, and an object of the present invention is to provide a new type of hose connection module for fluid delivery and an assembly method thereof, which enable stable press-fitting of a connection pipe without damaging a hose made of soft material.

In addition, an object of the present invention is to provide a hose connection module for fluid delivery and an assembly method thereof that enable a stable connection between a hose and a connection pipe without using a separate fastening aid and can be accurately coupled without damaging the hose.

In addition, an object of the present invention is to provide a new type of hose connection module for fluid transmission and an assembly method thereof, in which airtightness between a hose and a connection pipe can be stably maintained.

According to the hose connection module for fluid delivery of the present invention for achieving the above object, the connection hose is formed with an expansion tube that expands towards the end, and the connection pipe includes a press-fitting portion press-fitted into the connection hose, at least one locking protrusion formed on a circumferential surface of the press-fitting unit, and a supporting protrusion supporting the end of the connection hose. It is formed, characterized in that the press-fitting part is coupled by press-fitting into the connection hose while applying ultrasonic vibration.

Here, the portion between the supporting protrusion and the protrusion is characterized in that it is formed as an inclined surface having an inclination angle greater than that of the expansion part of the connecting hose or the same as the inclination of the expansion part.

In addition, the contact surface between the press-fitting part and the connecting hose is characterized in that it is configured to be in close contact with each other by melting with ultrasonic waves.

And, according to the assembly method of the hose connection module for fluid transmission of the present invention for achieving the above object, the hose preparation step of preparing the connection hose, the pipe preparation step of preparing the connection pipe, the temporary assembly step of temporarily assembling the connection pipe to the expansion part of the connection hose, and the coupling step of coupling the connection pipe to the connection hose. to be

In addition, after performing the coupling step, a cooling step of cooling the contact area between the press-fitting part and the connecting hose is performed.

As described above, the hose connection module for fluid transmission and the method of assembling the same according to the present invention have an effect of minimizing flow resistance generated in the course of fluid passing through a connection portion between a connection hose and a connection pipe.

In addition, the hose connection module for fluid delivery and the method of assembling the same according to the present invention do not create a gap between the outer circumferential surface of the end of the non-inclined end and the inner circumferential surface of the connecting hose, so that the flow resistance of the fluid passing through the connecting hose and flowing into the connecting pipe is prevented.

In addition, the hose connection module for fluid transmission and the method of assembling the same according to the present invention, due to the structure of the non-inclined end, prevents the connection hose from suddenly opening in the process of press-fitting the press-fitting part into the connection hose, thereby solving the problem of the connection hose being torn or stretched.

In particular, the hose connection module for fluid transmission and the method of assembling the same according to the present invention apply ultrasonic vibration to the connection pipe and press-fit it to the connection hose, so that the connection pipe can be press-fitted without damaging the connection hose even with a non-inclined end structure. It is possible to press-fit smoothly.

That is, since the connecting hose is expanded while being stretched by the frictional heat of ultrasonic waves, problems such as tearing of the corresponding connecting hose can be prevented.

As shown in these drawings, the hose connection module for fluid transmission according to the embodiment of the present invention is largely composed of a connection hose 100 and a connection pipe 200, and in particular, the connection pipe 200 is press-fitted to the connection hose 100 while applying ultrasonic vibration. Accordingly, the connection pipe 200 can be press-fitted without damaging the connection hose 100, and the contact surface between the connection hose 100 and the connection pipe 200 can be airtight.

That is, since the connecting hose 100 is expanded while being stretched by the frictional heat of ultrasonic waves, problems such as tearing of the corresponding connecting hose 100 can be prevented.

In particular, the hose connection module for fluid transmission according to an embodiment of the present invention allows the inner diameter of the connection hose 100 and the inner diameter of the connection pipe 200 to be formed to be the same, so that the fluid flows between the connection hose 100 and the connection pipe 200. Flow resistance generated in the process of passing through the connection portion can be minimized.

The hose connection module for fluid delivery according to the embodiment of the present invention will be described in more detail for each configuration as follows.

First, the connecting hose 100 is a hose provided to guide fluid flow.

Such a connection hose 100 may be formed of a flexible material capable of bending deformation or elongation. For example, the connection hose 100 may be formed of rubber or silicone material.

In addition, as shown in the attached FIG. 5, an expansion pipe 110 may be formed in the connection hose 100. The expansion part 110 is formed at a connection portion with a counterpart (connection pipe), which is the end of the connection hose 100.

That is, through the provision of the above-mentioned pipe expansion unit 110, the connection hose 100 can be prevented from momentarily excessively widening when the connection pipe 200 is press-fitted.

The expansion part 110 is formed in an inclined or rounded skirt shape so that it gradually expands toward the outside from the connection portion with the connection hose 100.

In particular, the inlet portion of the expansion pipe 110 is formed to have an inner diameter HD1 larger than the end outer diameter PD1 of the connecting pipe 200, which will be described later, and the outlet portion of the expansion pipe 110 (connecting portion with the connection hose) and the connection hose 100 are formed to have an inner diameter HD2 smaller than the end outer diameter PD1 of the connection pipe 200, which will be described later.

Next, the connection pipe 200 is a part that is press-fitted into the connection hose 100.

The connection pipe 200 may be provided to connect the connection hose 100 to other hoses or pipes, or to a structure through which fluid is stored or passed (eg, a filter housing for a water purifier, etc.).

As shown in the attached FIG. 6 , the connection pipe 200 may include a press-fitting portion 210 .

Here, the press-fitting part 210 is a part press-fitted to the connection hose 100 of the connection pipe 200 .

The outer diameter (PD1) of the press-fitting part 210 is larger than the inner diameter (HD2) of the connection hose 100, but smaller than the inner diameter (HD1) formed by the end (inlet side) of the expansion pipe 110. It is formed. That is, it is possible to press-fit the press-fitting part 210 into the inner surface of the connection hose 100.

In particular, the inner diameter (PD2) of the connection pipe 200 including the press-fitting part 210 is formed to be the same (completely the same or approximately the same) as the inner diameter (HD2) of the connection hose 100. That is, in a state in which the connection pipe 200 is press-fitted into the connection hose 100, the internal diameters HD2 and PD2 of each other are kept approximately the same, so that the fluid flowing along the connection hose 100 is provided with resistance. This is to prevent the phenomenon.

In addition, the press-fitting part 210 includes a non-inclined end 211 formed in a non-inclined structure and an inclined end 212 formed in an inclined structure.

Here, the non-inclined end 211 forms an end portion of the corresponding connection pipe 200 and is press-fitted into the inner circumferential surface of the connection hose 100.

In particular, the non-inclined end 211 is a portion extending from the end of the press-fitting portion 210 to the inclined end 212, and is formed so that the entire outer diameter remains the same. That is, the non-sloping end 211 is formed in the same horizontal structure as the inner circumferential surface of the connecting hose 100.

Accordingly, when the non-inclined end 211 is pressed into the inner circumferential surface of the connecting hose 100, it is possible to prevent a gap from being generated between the outer circumferential surface of the end of the non-inclined end 211 and the inner circumferential surface of the connecting hose 100. In addition, the problem that flow resistance is generated by the gap in the fluid passing through the connection hose and flowing into the connection pipe can also be prevented.

Of course, although not shown in detail, the edge of the non-inclined end 211 may be chamfered, but such a chamfered portion may be an extremely fine part of the non-inclined end 211.

And, the inclined end 212 is formed to form a portion from the non-inclined end 211 to the supporting protrusion 220.

The outer circumferential surface of the inclined end 212 is formed to have an inclination angle equal to or greater than the inclination of the expansion part 110 of the connection hose 100. That is, the inclined structure of the inclined end 212 allows the inner circumferential surface of the expansion pipe 110 of the connection hose 100 to come into close contact, thereby preventing a gap from being generated between them.

In addition, a locking protrusion 213 is protruded from the circumferential surface of the non-inclined end 211 of the press-fitting portion 210 .

The protrusion 213 is a portion formed to prevent unwanted separation while being fixed in a state where the press-fitting part 210 is pressed into the connection hose 100 and dug into the inner circumferential surface of the connection hose 100 . That is, the joint between the press-fitting part 210 using the fastening aid 300 and the connection hose 100 can be firmly fastened by the protrusion 213 .

These protrusions 213 are formed to gradually incline inward in the insertion direction of the press-fitting part 210, and the rear end is formed to form a right angle with respect to the outer surface of the non-sloping end 211. Of course, the rear end of the protrusion 213 may be formed to have a reverse inclination. That is, when the press-fitting part 210 is press-fitted into the connection hose 100 due to the structure of the rear end of the locking protrusion 213, the locking protrusion 213 is caught on the inner surface of the connecting hose 100. Separation in the opposite direction to the press-fitting can be prevented.

The protrusion 213 may be formed only one, or may be formed in a plurality of two or more. In the embodiment of the present invention, as an example, the protrusion 213 is formed in plurality along the axial direction of the press-fitting part 210 .

At this time, each of the protrusions 213 may be formed continuously or may be partially spaced apart from each other.

In particular, the protrusion 213 is configured to be formed at a portion spaced apart from the end of the non-inclined end 211 by a predetermined length.

A portion of a certain length from the end of the non-sloping end 211 forms the minimum outer diameter of the corresponding press-fitting portion 210 while passing through the expansion pipe 110 and press-fitting the inner circumferential surface of the connecting hose 100. In addition to serving to prevent the inclination of the connecting hose 100, it serves to prevent tearing of the connecting hose 100.

That is, in the prior art (eg, Patent No. 10-2223794), the reason why the end (No. 115 on the drawing of the prior art) of the discharge part (No. 110 on the drawing of the prior art document) (corresponding to the press-fitting part of the present invention) is formed as an inclined surface (No. 112 on the drawing of the prior art document) is to smoothly press-fit into the water outlet hose (No. 300 on the drawing of the prior document) (corresponding to the connection hose of the present invention). was However, in this structure, in the process of press-fitting the outlet hose into the outlet hose, as the outlet portion is pushed in, the opening of the outlet hose gradually increases along the inclined surface, resulting in unwanted tearing of the outlet hose.

In particular, in order to prevent tearing of the above-described water outlet hose, there is an inconvenience in connection work that requires attention to keep the press-in speed extremely low during the press-in operation.

However, in the case of the embodiment of the present invention, the phenomenon that the opening of the connection hose 100 gradually increases in the process of press-fitting the press-fitting part 210 into the connection hose 100 due to the non-inclination structure of the non-inclined end 211 does not occur.

As a result, problems such as tearing of the connecting hose 100 do not actually occur.

Of course, since the non-sloping end 211 of the press-fitting part 210 according to the embodiment of the present invention does not have a structure (inclined structure) that penetrates into the connecting hose 100 like the conventional structure, difficulties may occur during press-fitting. However, in the embodiment of the present invention, by providing ultrasonic vibration when the press-fitting part is press-fitted, it is possible to solve the above-described difficulty of press-fitting, while making it easy to elongate the connection hose 100 with frictional heat, thereby preventing tearing.

In addition, the connecting pipe 200 is formed with a supporting protrusion 220.

The support protrusion 220 is a portion provided to prevent excessive coupling of the connection hose 100 .

The support protrusion 220 may be formed to protrude by a height sufficient to support the expansion pipe 110 of the connection hose 100. That is, due to the provision of the supporting protrusion 220, coupling of the connection hose 100 beyond the position of the supporting protrusion 220 can be prevented.

Meanwhile, the press-fitting part 210 constituting the connection pipe 200 may be made such that ultrasonic vibration is applied during press-fitting into the connection hose 100 . That is, by applying ultrasonic vibration to the press-fitting part 210 so as to be press-fitted into the connecting hose 100, damage such as tearing of the connecting hose 100 is prevented when the press-fitting part 210 is press-fitted.

In particular, when the ultrasonic vibration is provided, since heat due to the ultrasonic vibration is generated between the two contact surfaces, the connection hose 100 is further softened to prevent the connection hose 100 from being torn.

In addition, after the press-fitting part 210 of the connection pipe 200 is press-fitted into the connection hose 100, the contact surface between the connection pipe 200 and the connection hose 100 can be completely adhered. As a result, water leakage to the contact surface between the connecting pipe 200 and the connecting hose 100 is prevented.

In addition, a mounting groove 310 into which the circumference of the supporting protrusion 220 can be mounted is formed on the inner circumferential surface of the fastening aid 300, thereby preventing unwanted separation of the fastening aid 300 and the connecting pipe 200. The protrusion 213 can be maintained press-fitted into the inner surface of the connecting hose 100.

In the following, the assembly method of the hose connection module for fluid delivery according to the embodiment of the present invention described above will be described in more detail for each process with reference to the state diagrams of FIGS. 7 to 10 attached.

First, the connection pipe 200 is prepared. At this time, at least a portion of the connection pipe 200 is installed to receive ultrasonic vibration from an ultrasonic generator (not shown) that generates ultrasonic vibration.

Along with this, the connection hose 100 is prepared. At this time, the connection hose 100 is positioned so that the part where the expansion part 110 is formed faces the press-fitting part of the connection pipe 200.

In addition, the press-fitting part 210 of the connection pipe 200 is partly coupled to the prepared pipe expansion part 110 of the connection hose 100 to be temporarily assembled.

At this time, the temporary assembly is a preparation process for ensuring that the connection hose 100 is accurately coupled to the correct position without bending or twisting during the coupling step.

Particularly, in the temporary assembly process, a part of the press-fitting part 210 is assembled to the extent that unwanted inclination can be prevented while being press-fitted into the expansion tube 110. For example, at least 1/3 to 1/4 of the non-sloping end 211 is assembled so that it can be press-fitted into the expansion part 110 of the connection hose 100. This is as shown in the attached Figures 7 and 8.

Then, when the temporary assembly is completed, the ultrasonic generator is operated to provide ultrasonic vibration to the press-fitting part 210 of the connection pipe 200, and at the same time pressurize the connecting hose 100 so that the press-fitting part 210 is press-fitted into the corresponding connection hose 100.

The ultrasonic vibration provided to the connection pipe 200 serves to ensure that the non-inclined end 211 of the press-fitting part 210 has a non-inclined structure and is smoothly pushed into the connection hose 100 despite having a larger outer diameter PD1 than the inner diameter HD2 of the connection hose 100.

The vibration does not achieve an exact parallel state with the connection hose 200 while the press-fitting part 210 is forcibly press-fitted into the connecting hose 100 and tilts or bends, so that even if the press-fitting part 210 is caught at the corresponding part, it will play a role in preventing restraint. That is, since the jamming of the press-fitting part 210 is quickly resolved by the vibration, damage (stretching or tearing) of the connecting hose 100 due to excessive restraint is prevented and the press-fitting part 210 can be smoothly inserted into the connecting hose 100.

In particular, when ultrasonic vibration is generated, heat is generated due to the ultrasonic vibration to the surface of the press-fitting part 210 and a part (inner surface of the connecting hose) to which the press-fitting part 210 is in contact. As a result, the connection hose 210 made of soft material achieves a softer state (easily stretchable state) due to the heat effect of the ultrasonic vibration, and even though its inner diameter (HD2) is smaller than the outer diameter (PD1) of the press-fitting part 210, the press-fitting part 210 can be smoothly press-fitted.

In addition, the expansion part 110 provided to the connection hose 100 serves to reduce the amount of opening of the connection hose 100 when the connection hose 100 is rapidly opened due to the instantaneous press-fitting of the press-fitting part 210. That is, since the expansion part 110 is provided in a state opened in advance as much as the diameter at which the connection hose 100 can be opened, even if the connection hose 100 is expanded while the press-fitting part 210 is press-fitted, the deformation of the connection hose 100 is partially offset by the structure of the expansion part 110.

Accordingly, rapid excessive expansion of the connecting hose 100 is not made, so that damage such as tearing or stretching of the connecting hose 100 can be prevented.

In addition, in a state in which the press-fitting part 210 of the connecting pipe 200 is completely inserted into the connecting hose 100 by the coupling process, the end of the connecting hose 100 (the end of the pipe expansion part) is supported by the supporting protrusion 220 of the connecting pipe 200, so that it is no longer inserted. Thus, excessive insertion of the connecting pipe 200 can be prevented. This is as shown in the attached Figures 9 and 10.

In addition, when the press-fitting part 210 of the connecting pipe 200 is completely inserted into the connecting hose 100, the expanding part 110 of the connecting hose 100 is in close contact with the inclined end 212 of the connecting pipe 200. As a result, the occurrence of a gap between the expansion tube 110 and the inclined end 212 can be prevented, and foreign substances can be prevented from penetrating into the gap.

In addition, when the press-fitting part 210 of the connecting pipe 200 is completely inserted into the connecting hose 100, the operation of the ultrasonic generator is terminated and the joint between the connecting pipe 200 and the connecting hose 100 is cooled.

That is, in the above cooling process, a phenomenon in which heat generated by ultrasonic vibration affects a corresponding joint site after coupling between the connecting hose 100 and the connecting pipe 200 (e.g., thermal deformation of the connecting hose, or a separation phenomenon that may be caused by maintaining the ductility of the connecting hose) is prevented. At this time, the cooling of the bonding portion may be rapidly cooled by blowing cold air, or natural cooling may be performed by maintaining the joint in a natural state.

Eventually, the connection between the connection pipe 200 and the connection hose 100 is completed through the above process. That is, the press-fitting portion 210 of the connecting pipe 200 is press-fitted into the connecting hose 100 and maintained in a fixed state.

Of course, a fastening aid may be additionally fastened to a joint between the connecting hose 100 and the connecting pipe 200. Accordingly, separation of the connection hose 100 from the connection pipe 200 can be further prevented.

In particular, since the fastening aid presses the rear end of the locking protrusion 213, the connection hose 100 can be prevented from being separated by the holding force of the locking protrusion 213.

As such, in the hose connection module for fluid transmission of the present invention, since the inner diameter (HD2) of the connection hose 100 and the inner diameter (PD2) of the connection pipe 200 are formed identically, the fluid is connected to the connection hose 100 and the connection pipe 200. Flow resistance generated in the process of passing through the connection portion can be prevented or minimized.

In addition, in the hose connection module for fluid transmission of the present invention, since the end of the press-fitting part 210 constituting the connecting pipe 200 is formed as a non-sloping end 211 having the same outer diameter, the outer circumferential surface of the end of the non-sloping end 211 and the inner circumferential surface of the connection hose 100 can be prevented from occurring. As a result, the fluid passing through the connection hose 100 and flowing into the connection pipe 200 is prevented from generating flow resistance due to the gap.

In particular, due to the structure of the non-inclined end 211, rapid opening of the connection hose 100 is prevented in the process of press-fitting the press-fitting part 210 into the connection hose 100, so that the connection hose 100 is torn or stretched. It is possible to solve the problem.

Of course, the structure of the non-inclined end 211 has a problem that it is not smoothly pressed into the connection hose 100.

However, the hose connection module for fluid transmission and the method for assembling the same according to the present invention apply ultrasonic vibration to the connection pipe 200 so as to be press-fitted to the connection hose 100, so that the connection pipe 200 can be press-fitted without damage to the connection hose 100, while smooth press-fitting is possible.

An outer diameter larger than the inner diameter of the connecting hose and formed smaller than the inner diameter formed by the end of the expansion tube, and a non-inclined end formed to have an outer diameter larger than the inner diameter of the connecting hose and smaller than the outer diameter of the connecting hose, and extending from the non-inclined end and having a larger outer diameter than the non-inclined end and an inclined end that slopes so that the outer diameter gradually increases toward the end, and a part of the non-inclined end has a length of at least half or more of the length of the expansion part; In addition, a pipe preparation step of preparing a connection pipe including a press-fitting part formed to have the same outer diameter and press-fitted into the connection hose, and a supporting protrusion supporting an end of the connection hose;
A provisional assembly step of temporarily assembling the non-inclined end of the press-fitting part of the connection pipe by press-fitting it into the expansion part of the connection hose;
Applying ultrasonic vibration to the temporarily assembled connection pipe and simultaneously moving the connection hose to the connection pipe, gradually pushing the press-fitting part of the connection pipe into the connection hose until the end of the connection hose collides with the supporting protrusion. Coupling step;
When the press-fitting part of the connecting pipe is completely inserted into the connecting hose and the end of the connecting hose hits the supporting protrusion of the connecting pipe, the movement of the connecting hose is stopped and the operation of the ultrasonic generator is terminated. A cooling step of cooling the contact area between the press-fitting part and the connecting hose; delete
