Description

Technical Field

[0001] The present disclosure relates to a connector for a pump. More particularly, the present disclosure relates to such a connector for a pump, which provides simple and convenient coupling or adjustment of a hose attached thereto. Background Art

[0002] A pump is a device that allows the transfer of fluids (such as liquids or gases, or sometimes slurries) by mechanical action. For example, a submersible pump is a device with a hermetically sealed motor tightly coupled to the pump body. A submersible pump can be immersed in the fluid to be pumped. Typically, pumps are used to pump water from wells, or for filtering aquariums, ponds, or can be used in the automotive industry or the energy industry for the desired purpose.

[0003] A connector is a device that connects or associates two or more parts together. In the case of these pumps, a hose connector is applied as a hose connection device. A hose connector can be provided at the end of a hose. A hose connector can connect a hose to another hose or a faucet or a facility such as an irrigation sprinkler, pump, etc.

[0004] However, there may be situations where coupling of the hose to the pump may become a cumbersome process. Assembly or disassembly of the hose to the pump may require undesirable forces. Furthermore, assembly or disassembly of the hose to the pump may require an unreasonable amount of time. Furthermore, many technical problems may occur during assembly or disassembly of the hose to the pump.

[0005] Korean Patent 101,509,191 (hereinafter referred to as the '191 reference) provides an example of a connector. The '191 reference provides a clamping portion for connection. In one embodiment, the connection simply includes: pressing two pushing units to elastically deform the band and easily installing the fixed clamping portion to the female connector and the male connector to obtain the desired connection arrangement. When an external force is applied, the band can be easily elastically deformed using the pushing unit of the fixed clamping portion. Thereby, the locked state of the fixed clamping portion and the male connector can be released. However, the '191 reference does not seem to mention any components or arrangements for checking or preventing accidental movement or unlocking of the pushing unit of the fixed clamping portion. In addition, there seems to be a lack of any emphasis on any support or locking on the pushing unit during the locking of the fixed clamping portion with the female connector and / or the male connector.

[0006] US 5704658 provides an example of a connector, which provides a clamping portion for preventing a pipeline from being removed from a body. The clamping portion has a knob, which is operated to move toward each other for expanding the diameter of the clamping portion to be enough to make the engagement claws assembled on the clamping assembly portion of the body. The clamping portion with an expanded diameter is then assembled on the clamping assembly portion until the front end of the clamping portion is close to the stepped wall of the body, so that the engagement claws of the clamping portion are brought to the position for inserting the engagement hole of the body. Then, the knob is released to allow the diameter of the clamping portion to be reduced by its elasticity, so that the engagement claws are brought to engage with the engagement hole. However, the current reference does not seem to provide any arrangement or mode to limit or stop any unexpected movement of the knob, such as movement without any user action. In addition, in addition to other implementation benefits, such an arrangement or mode can also support the knob, and thereby support the clamping portion to have the desired engagement with the body and / or pipeline.

[0007] Thus, there is a need for an improved connector for a pump that allows safe, convenient and trouble-free coupling of a hose to the pump. Summary of the invention

[0008] In view of the above, an object of the present invention is to solve or at least reduce the disadvantages discussed above. This object is achieved at least in part by a connector for a pump. The pump includes a body. The body includes an inlet and an outlet. The connector also includes a first connector part and a second connector part. In addition, the first connector part includes a first end and a second end. The first end of the first connector part is connected to the outlet of the pump. In addition, the second connector part includes a first end and a second end. The first end of the second connector part is suitable for connecting to the second end of the first connector part, and the second end of the second connector part is suitable for connecting to a hose. In addition, the second end of the second connector part is oriented at an angle relative to the first end of the first connector part. The connector also includes a connecting mechanism. The connecting mechanism connects the second end of the first connector part and the first end of the second connector part. The connector is characterized in that the connecting mechanism can be moved between a closed position and an open position based on the actuation of an elastic part of the connecting mechanism. The elastic part of the connecting mechanism includes a first protrusion and a second protrusion. The first protrusion is connected to a first annular part. In addition, the first annular part at least partially surrounds the first connector part. The second protrusion is connected to the second annular part. In addition, the second annular part at least partially surrounds the second connector part. This can provide effective and optimal engagement of the first connector part and the second connector part. In addition, in the closed position of the connecting mechanism, the second connector part remains connected to the first connector part. In the open position of the connecting mechanism, the second connector part can be separated from the first connector part. The first protrusion and the second protrusion are movable relative to each other, and when the first protrusion and the second protrusion move toward each other, the connecting mechanism changes from the closed position to the open position. This can make the assembly and disassembly of the first connector part and the second connector part less involved in the force. In addition, a stop pin is provided between the first protrusion and the second protrusion, preferably on the elastic part itself, and the stop pin forms an interference with the first protrusion and / or the second protrusion, and thus limits the movement of the first protrusion and / or the second protrusion. Thus, the stop pin helps to ensure that as the first protrusion and the second protrusion move toward each other, the two protrusions move simultaneously.

[0009] Thus, the present disclosure provides a simple, efficient and convenient connection and disconnection of the hose and the second connector part connected thereto with the pump. This type of connector can be used even in cases where the hose is rigid or there are problems with torsion forces acting on it and is superior to the connections known from the prior art.

[0010] According to an embodiment of the present invention, the first annular portion and the second annular portion comprise locking elements. These locking elements allow the desired engagement of the elastic member with the first connector part.

[0011] According to an embodiment of the invention, the first annular portion and the second annular portion are formed integrally. In this case, the resilient portion of the connector forms a single element that is easy to handle, particularly during assembly.

[0012] According to an embodiment of the invention, wherein the resilient portion is associated with the first connector part via a pin, the pin holds the resilient portion in position relative to the first connector part in the region of the pin even in the event of a movement of the first and / or second protrusion.

[0013] According to an embodiment of the present invention, the first annular portion and the second annular portion comprise complementary structural arrangements. This may provide a desired engagement of the first annular portion and the second annular portion.

[0014] According to an embodiment of the present invention, the elastic portion is manufactured by three-dimensional printing. In addition, a data file is provided, which corresponds to pre-stored instructions including a digital representation of the elastic portion, and when the pre-stored instructions are executed in a processor, controls the operation of a three-dimensional printer so that the three-dimensional printer prints the elastic portion. The use of three-dimensional printing (alternatively, 3D printing) can provide versatility in using different materials and lower lead time in the manufacture and design of the elastic portion.

[0015] According to an embodiment of the invention, the second connector part comprises a leg. The leg can engage with a complementary geometric structure of the second end of the first connector part to provide a secure attachment.

[0016] According to an embodiment of the invention, the first end of the second connector part and the second end of the first connector part have complementary geometric structures for coupling. This can provide a better and waterproof coupling of the first connector part and the second connector part.

[0017] According to an embodiment of the present invention, the connector is made of one or more materials selected from steel, brass, stainless steel, aluminum or plastic. The properties of the material can provide the connector with desired characteristic features.

[0018] According to an embodiment of the present invention, the elastic part is a clamping part, which allows ordinary users to connect the second connector part with the first connector part with less effort.

[0019] According to an embodiment of the invention, the first end of the second connector part and the second end of the first connector part comprise one or more seals. Among other functional benefits, the one or more seals may complement the waterproof connection between the first connector part and the second connector part.

[0020] Other features and aspects of the present invention will be apparent from the following description and accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Fig. 1 shows a pump 100 with a conventional connector 110. The pump 100 can be a machine device for pumping fluids (such as liquids, gases, or sometimes mud). The pump 100 of the present disclosure can be a submersible pump, which can be used indoors or outdoors according to the application needs of ordinary users. The pump 100 includes a body 104. The body 104 has an inlet 108 and an outlet 113. The body 104 also includes a base 106. The inlet 108 is present at the base 106 of the pump 100. The inlet 108 can allow fluid to enter the pump 100. In addition, the outlet 113 can be arranged near the base 106 of the pump 100. The outlet 113 can discharge the pumped fluid. The discharged fluid can be used for different applications, such as irrigation, washing, etc.

[0030] In addition, the pump 100 has a handle 112. The handle 112 can be used to raise or shift the pump 100. The conventional connector 110 includes a first connector portion 114 and a second connector portion 116. The first connector portion 114 has a first end 118 of the first connector portion 114 and a second end 120 of the first connector portion 114. The first end 118 of the first connector portion 114 is coupled to the outlet 113 of the pump 100. The second connector portion 116 includes a first end 122 of the second connector portion 116 and a second end 124 of the second connector portion 116. The second end 124 of the second connector portion 116 is coupled to the hose 111. In addition, the first end 122 of the second connector portion 116 is detachably screwed with the second end 120 of the first connector portion 114.

[0031] Figure 2 A pump 100 having a connector 210 is shown. The pump 100 of the present disclosure utilizes the connector 210 to connect two connector parts associated with the pump 100. More specifically, the connector 210 of the pump 100 includes a first connector part 214 and a second connector part 216. The first connector part 214 includes a first end 218 and a second end 220. In addition, the first end 218 of the first connector part 214 is coupled to the outlet 113 of the pump 100. The second connector part 216 includes a first end 222 and a second end 224. The second end 224 of the second connector part 216 is coupled to the hose 111. In addition, the first end 222 of the second connector part 216 is coupled to the second end 220 of the first connector part 214.

[0032] The second end 224 of the second connector portion 216 is oriented at an angle relative to the first end 218 of the first connector portion 214. The connector 210 also includes an elastic portion 226. The elastic portion 226 couples the first connector portion 214 and the second connector portion 216 together. The connecting mechanism connects the second end 220 of the first connector portion 214 and the first end 222 of the second connector portion 216. The connecting mechanism can move between a closed position and an open position (in Figure 3 and Figure 4 ).

[0033] In some embodiments, the elastic portion 226 is made of one or more materials selected from steel, brass, stainless steel, aluminum or plastic. The properties of the material are selected according to the requirements of ordinary users. The desired properties of the material can provide certain characteristic features (such as flexibility, elasticity, heat resistance or vibration resistance) for the elastic portion 226.

[0034] In some embodiments, the elastic portion 226 can be manufactured using any process such as casting, molding, forging, assembly, etc. In other embodiments, the elastic portion 226 can be manufactured by three-dimensional printing (also known as additive manufacturing or 3D printing). In some embodiments, the data file corresponds to pre-stored instructions that include a digital representation of the elastic portion 226 and control the operation of the three-dimensional printer when the pre-stored instructions are executed in the processor, so that the three-dimensional printer prints the elastic portion 226. The use of three-dimensional printing (alternatively, 3D printing) provides versatility in using different materials and low lead time in the manufacture and design of the elastic portion 226.

[0035] Figure 3 The connection structure between the first connector part 214 and the second connector part 216 in a disassembled state is shown. In the open position of the connection mechanism, the second connector part 216 is separated from the first connector part 214. In the depicted embodiment, the second connector part 216 has a stepped configuration 228. The stepped configuration 228 of the second connector part 216 allows the hose 111 to be coupled with different steps of the stepped configuration 228. The second connector part 216 includes a leg 230. The leg 230 engages with the complementary geometry 244 of the second end 220 of the first connector part 214. The leg 230 is attached to the flange 232 of the second connector part 216. The flange 232 can provide stability and a desired coupling with the second connector part 216 while being assembled with the first connector part 214.

[0036] In some embodiments, the stepped configuration 228 can allow different hoses to be coupled to the same second connector portion 216. Hoses with different diameters or similar sizes can be accommodated at different steps of the second connector portion 216. Alternatively or additionally, the second end 224 of the second connector portion 216 can be provided with a threaded structure to couple with the hose 111.

[0037] Furthermore, the elastic portion 226 is disposed proximate to the second end 220 of the first connector portion 214. The elastic portion 226 includes a first protrusion 234. Furthermore, the elastic portion 226 includes a second protrusion 236. Furthermore, the first protrusion 234 is coupled to the first annular portion 238. The second protrusion 236 is coupled to the second annular portion 240.

[0038] A pin 242 and associated slot (not shown) are provided for engaging both the resilient portion 226 and the first connector portion 214, preferably around the second end 220 of the first connector portion 214. The pin 242 engages the first annular portion 238 and the second annular portion 240, as shown in FIG. Figure 4 , Figure 5 As shown. The pin 242 can hold the first annular portion 238 and the second annular portion 240 together and prevent any accidental movement thereof. Even in the case of movement of the first protrusion 234 and / or the second protrusion 236, in the region of the pin 242, the pin 242 keeps the elastic portion 226 in place relative to the first connector portion.

[0039] In some embodiments, there may be a snap connection to hold the first annular portion 238 and the second annular portion 240 together. In another embodiment, a screw or any other fastener known or used in the art may be provided. Alternatively or additionally, the first annular portion 238 may have serrations. The serrations may engage with complementary serrations of the second annular portion 240. According to an embodiment of the present invention, the first annular portion 238 and the second annular portion 240 are integrally formed.

[0040] Figure 4The first connector portion 214 and the second connector portion 216 are shown in an assembled state. In the closed position of the connection mechanism, the second connector portion 216 remains coupled to the first connector portion 214. The first end 222 of the second connector portion 216 engages with the second end 220 of the first connector portion 214. The flange 232 can help the second connector portion 216 have the desired engagement and stability with the first connector portion 214. The leg 230 of the second connector portion 216 engages with the complementary geometric structure 244 of the second end 220 of the first connector portion 214. The complementary geometric structure 244 can also provide a waterproof connection. The leg 230 of the second connector portion 216 and the complementary geometric structure 244 of the first connector portion 214 engage to provide a desired lock between the first connector portion 214 and the second connector portion 216.

[0041] Preferably, a seal (not shown), such as an O-ring seal, is provided between the first connector portion 214 and the second connector portion 216. Such a seal supplements the waterproofness of the connection between the second end 220 of the first connector portion 214 and the first end 222 of the second connector portion 216.

[0042] In some embodiments, the first end 222 of the second connector portion 216 can have protrusions that can engage with complementary grooves provided on the second end 220 of the first connector portion 214, or vice versa.

[0043] In some embodiments, an O-ring or a gasket may be used to connect the second end 220 of the first connector portion 214 and the first end 222 of the second connector portion 216 .

[0044] The first end 222 of the second connector portion 216 and the second end 220 of the first connector portion 214 form a waterproof connection. The waterproof connection can be obtained by attaching an O-ring (not shown). The O-ring can supplement the seal between the first connector portion 214 and the second connector portion 216 to provide a waterproof connection. In some embodiments, a waterproof connection can be obtained by using a gasket. Alternatively or additionally, a waterproof coating can be used to obtain a waterproof connection. Figure 5 Shown along Figure 4226. The connection mechanism can be moved between a closed position and an open position based on the actuation of the elastic portion 226. The first protrusion 234 and the second protrusion 236 are pressed together to change the connection mechanism from the closed position to the open position. In the depicted embodiment, a stop pin 237 is provided between the first protrusion 234 and the second protrusion 236, preferably on the elastic portion 226 itself, and the stop pin is formed to interfere with the first protrusion and / or the second protrusion, and thereby limit the movement of the first protrusion 234 and / or the second protrusion 236. Thus, the stop pin 237 helps to ensure that as the first protrusion 234 and the second protrusion 236 move relative to each other, the two protrusions move simultaneously.

[0045] like Figure 5 As shown, the first protrusion 234 is set to the first annular portion 238. The second protrusion 236 is set to the second annular portion 240. The first annular portion 238 and the second annular portion 240 at least partially surround the first connector portion 214. In some embodiments, either or both of the first protrusion 234 and the second protrusion 236 are pressed together to change the connection mechanism from a closed position to an open position. Based on the disengagement or release of the elastic portion 226 from the first connector portion 214, this can require less force to assemble or disassemble the first connector portion 214 and the second connector portion 216. Preferably, the stop pin 237 limits the movement of the first protrusion 234 and the second protrusion 236, which in most cases is generated when force is applied to both the first protrusion and the second protrusion via the user's fingers.

[0046] The first annular portion 238 and the second annular portion 240 include a locking piece 248. The locking piece 248 allows the desired engagement of the elastic portion 226 with the first connector portion 214. In some embodiments of the present disclosure, either or both of the first connector portion 214 and the second connector portion 216 may be provided with a recess for engaging with the locking piece 248 of the first annular portion 238 and the second annular portion 240.

[0047] like Figure 5 As shown, the first annular portion 238 and the second annular portion 240 are enlarged along the axis AA'. This configuration change along the axis AA' can allow for better insertion / engagement of the second end 220 of the first connector portion 214 and the first end 222 of the second connector portion 216.

[0048] In some embodiments, the connection mechanism provided by the present disclosure can be moved between a closed position and an open position based on the actuation of the elastic portion 226 of the connection mechanism. The elastic portion 226 of the connection mechanism includes a first protrusion 234 coupled to a first annular portion 238. The first annular portion 238 at least partially surrounds the first connector portion 214. And, the elastic portion 226 includes a second protrusion 236 coupled to a second annular portion 240. The second annular portion 240 at least partially surrounds the second connector portion 216. In the closed position of the connection mechanism, the second connector portion 216 remains coupled to the first connector portion 214. And, in the open position of the connection mechanism, the second connector portion 216 is separated from the first connector portion 214. In addition, the first protrusion 234 and the second protrusion 236 can move relative to each other, and when the first protrusion 234 and the second protrusion 236 move toward each other, the connection mechanism changes from the closed position to the open position. Furthermore, the stop pin 237 is preferably on the elastic portion 226 and located between the first protrusion 234 and the second protrusion 236 , and is formed to interfere with the first protrusion and / or the second protrusion and thereby limit the movement of the first protrusion 234 and / or the second protrusion 236 .

[0049] In this embodiment, the elastic portion 226 can be a clamping portion. In addition to other functional benefits, the simple and convenient buckling action based on the elastic portion 226 can enable ordinary users to connect or disconnect the second connector portion 216 and the first connector portion 214 with less effort.

[0050] In the drawings and specification, preferred embodiments and examples of the present invention have been disclosed, and although specific terms are employed, they are used in a generic and descriptive sense only and not for the purpose of limiting the scope of the invention set forth in the appended claims.
