Description

Water injection line connector

This work is related to the structure of a joint, especially a water injection pipeline joint that can be assembled quickly.

In today's society, more and more people keep pets, and pets are often left alone at home. Therefore, there are many pet drinking devices on the market that can meet the basic drinking needs of pets. For example, the pet drinking water device provided by Chinese patent No. CN101816289 mainly provides drinking water stored in the container of the pet drinking water device through an external water injection pipe. However, when the drinking water is directly exposed and not filtered, the dirt in the drinking water will continue to accumulate, and the bacteria will gradually multiply in the drinking water, seriously affecting the health of the pet. The pet drinking water device provided by Chinese patent No. CN107522326 focuses on the consideration of drinking water safety, and a filter that can filter the water flow is attached to the pet drinking water device to ensure the cleanliness of the drinking water.

All pet drinking water devices in the aforementioned patents or on the market must be cleaned manually after being used for a period of time to avoid dirt accumulation. Before cleaning, the user must first remove the water injection pipe connected to the pet drinking water device to facilitate subsequent cleaning. However, the aforementioned patents adopt a structural design that directly connects the water injection pipe to the inside of the pet drinking water device, which makes the disassembly and assembly of the water injection pipe quite time-consuming. It is not possible to quickly disassemble and assemble; furthermore, general water filling pipes do not have the function of automatic water stopping. Therefore, in order to avoid water overflow when removing the water filling pipe, the user must first turn off the water supply at the water source end before removing the water filling pipe, which is quite troublesome. Even if the water supply at the water source end has been turned off, the water remaining in the water filling pipe will still overflow when the water filling pipe is removed, resulting in the existing pet drinking device being quite troublesome and inconvenient when disassembling and assembling the water filling pipe, and there is still room for improvement.

In view of this, how to improve the above problems is the primary issue that this creation aims to solve.

The main purpose of this invention is to provide a water injection pipeline connector, which has the function of quickly installing and removing the water injection pipeline and can provide the function of filtering water quality; in addition, it can also provide the function of definitely stopping water when the water injection pipeline is removed.

To achieve the aforementioned purpose, the present invention provides a water injection pipeline connector, comprising: A first pipe diameter connector, one end of which has a quick-connect port, and the other end of the first pipe diameter connector has a connecting end; A second pipe diameter joint piece has a connecting portion at one end, the second pipe diameter joint piece is connected to the connecting end of the first pipe diameter joint piece by the connecting portion, and the other end of the second pipe diameter joint piece forms a tubular connecting portion, the second pipe diameter joint piece is composed of a cover body and a barrel body connected to each other, the cover body has the connecting portion, and the barrel body is connected to the cover body at one end, and the other end of the barrel body protrudes outward to form the connecting portion, and a tubular filter element is provided in the barrel body, so that a filtering space is formed inside the filter element, and the water source entering the barrel body through the connecting portion can provide filtering when passing through the filter element, and the water source entering the filtering space flows into the first pipe diameter joint piece again.

Preferably, the first diameter pipe joint has a collar and a joint member assembled in the collar, the collar has a first end facing the connecting end and a second end opposite to the first end, the joint member is tubular and has a joint hole inside, the joint member has an outer convex plate formed at the end edge facing the first end, and a plurality of buckle holes are opened on the outer convex plate, and An elastic fastener has a C-shaped ring portion, and the elastic fastener is arranged on an outer peripheral surface of the connecting member with its ring portion, and a plurality of hook claws are formed on the ring portion, and the extended end of each hook claw has a hook portion extending into the connecting hole, and an elastic member is arranged between the connecting member and the ring, and the two ends of the elastic member are respectively abutted against the outer convex plate and the On a stepped surface of the inner edge of the second end, a convex portion of the inner edge of the ring can be relatively pressed against each hook claw, and the connecting portion is provided with a plurality of buckling pins protruding axially thereof and buckled with each buckling hole, and a tubular connecting portion is formed at the other end of the second tube diameter joint piece, and the second tube diameter joint piece is composed of a cover body and a barrel body connected together, and the cover body has the connecting portion, and the connecting piece protrudes outward at one end toward the outer convex plate to form a connecting pipe connected to the connecting hole, and the inner part of the connecting portion encloses a channel for the connecting pipe of the first tube diameter joint piece to be connected, so that after the buckling pins are buckled with the buckling holes, the connecting pipe of the first tube diameter joint piece can be correspondingly inserted into the channel of the second tube diameter joint piece.

Furthermore, the connecting piece is formed with a connecting pipe connected to the connecting hole by protruding outward at one end of the connecting piece toward the outer convex plate, and a valve is provided in the connecting pipe for controlling the conduction state between the connecting pipe and the connecting hole. When the connecting hole of the first pipe diameter connecting piece is relatively sleeved on the water inlet end of a water supply device, the water inlet end of the water supply device will be relatively pushed and positioned at the connecting hole. The valve member in the through pipe is separated from the port of the connecting pipe, so that the connecting pipe is in a conducting state; and when the water inlet end of the water supply device is relatively withdrawn from the connecting hole of the first pipe diameter joint and no longer pushes the valve member, the water pressure input from the joint pushes the valve member in the reverse direction, so that the valve member can relatively close the port of the connecting pipe, so that the connecting pipe is in a water-stopping state.

The above-mentioned purposes and advantages of this invention can be easily understood from the detailed description and accompanying drawings of the following selected embodiments.

Please refer to Figures 1 to 5, which are the water injection pipeline joint 10 provided by the present invention, which is mainly composed of a first pipe diameter joint piece 11 and a second pipe diameter joint piece 41 connected to each other, wherein:

The first pipe diameter joint 11 has a quick-connect port 111 at one end for performing a quick-connect wiring function, and a connecting end 112 at the other end; preferably, the first pipe diameter joint 11 has a hollow sleeve 12 and a joint 13 coaxially arranged in the sleeve 12, the sleeve 12 has a first end 121 facing the connecting end 112 and a second end 122 opposite to the first end 121, and the joint 13 is tubular and has a joint hole 112 formed inside thereof for being sleeved with a water inlet end 51 of a water supply device. 31, the connecting hole 131 has a first pipe diameter, and the connecting member 13 is formed with an outer convex plate 132 at the end edge toward the first end 121, and a plurality of buckle holes 133 are formed on the outer convex plate 132, and the connecting member 13 is formed with a connecting pipe 134 that is connected to the connecting hole 131 and protrudes outward from one end toward the outer convex plate 132, and a valve 14 is provided in the connecting pipe 134 for controlling the conduction state between the connecting pipe 134 and the connecting hole 131, and an elastic fastener 21 has a C-shaped The elastic fastener 21 is relatively surrounded by the ring portion 22 on an outer peripheral surface 135 of the connecting member 13. The ring portion 22 is formed with a plurality of hooks 23 that surround the ring portion 22 and are arranged at intervals on one side of the ring portion 22 toward the second end 122. The extended end of each hook 23 has a hook portion 231 that passes through the outer peripheral surface 135 and extends relatively into the connecting hole 131. An elastic member 31 composed of a compression spring is coaxially sleeved between the connecting member 13 and the sleeve ring 12, and the elastic member 31 is The two ends are respectively in contact with the outer convex plate 132 and a stepped surface 123 on the inner edge of the second end 122, so that a convex portion 124 on the inner edge of the ring 12 can be pressed against each hook 23, so that each hook 23 is in a clamping state that cannot expand and deform; and when the ring 12 is pushed by an external force and moves axially relative to the connecting member 13, the elastic member 31 is compressed and the pressing effect of the convex portion 124 on each hook 23 is released, so that the convex portion 124 is no longer pressed against each hook 23, thereby releasing its clamping state. Preferably, the end edge of the connecting member 13 toward the second end 122 is expanded to form a flange 136, and a plurality of grooves 137 are recessed on the flange 136 and arranged at intervals. When the connecting member 13 is relatively assembled in the collar 12, at least one baffle 125 on the inner edge of the collar 12 will be relatively clamped against the side wall of the flange 136 toward the first end 121, so that the connecting member 13 can be axially positioned in the collar 12, and the inner edge of the collar 12 is A plurality of axially extending inserts 126 are further provided, and when the coupling 13 is relatively assembled in the collar 12, the inserts 126 will be relatively embedded in the grooves 137, thereby limiting the radial rotation of the collar 12, which not only facilitates the assembly of the collar 12 and the coupling 13, but also provides a guiding effect and prevents the collar 12 from rotating when the collar 12 is pushed by an external force and moves axially relative to the coupling 13, thereby improving its operability.

The second diameter pipe joint member 41 is composed of a cover 42 and a barrel 43 connected to each other in this embodiment. The cover 42 has a connecting portion 421, and the connecting portion 421 is used to connect with the connecting end 112 of the first diameter pipe joint member 11. In this embodiment, the connecting portion 421 is provided with a plurality of buckle pins 422 protruding in the axial direction thereof and used to buckle with each buckle hole 133, and the inner part of the connecting portion 421 encloses a first diameter pipe. The connecting tube 134 of the joint member 11 is connected to the channel 423, so that the buckle pins 422 and the buckle holes 133 are buckled with each other, and the connecting tube 134 of the first diameter joint member 11 can be correspondingly inserted into the channel 423 of the second diameter joint member 41, and the barrel 43 is locked with the cover 42 at one end, and the other end of the barrel 43 protrudes outward to form a tubular joint 431 that is connected to the external space, and the joint 431 has a connection with the cover 42. The second pipe diameter of the connecting hole 131 is different from that of the connecting hole 131, and an external thread 432 is provided on the connecting portion 431, so that a water injection pipeline 61 can be locked and connected to the connecting portion 431 through a screw connection 62, and a filter core 44 is provided in the barrel 43, and the filter core 44 is composed of a tubular PP cotton filter core, so that a filtering space 441 communicating with the channel 423 is formed inside the filter core 44, so that the water entering the second pipe diameter connecting member 41 through the connecting portion 431 can pass through the connecting portion 431. The water source in the filter element 44 can provide filtering when passing through the tube wall of the filter element 44 and entering the filter space 441 thereof, and after entering the filter space 441, it flows into the first pipe diameter joint 11 through the channel 423 and the connecting tube 134 in sequence, so that the external water source can be filtered first and then transported to the water inlet end 51 of the water supply device, and the filter space 441 can be additionally filled with other filter materials (such as activated carbon, nanosilver, etc.) according to actual needs to enhance its filtering effect.

When the invention composed of the above structure is actually used, as shown in FIG. 4, when the user relatively sleeves the first pipe diameter joint member 11 with the water inlet end 51 of the water supply device through the connecting hole 131, the hook portion 231 of each hook claw 23 of the elastic fastener 21 can be relatively hooked on a groove portion 52 of the water inlet end 51 of the water supply device, and the position of the ring 12 is maintained through the elastic resistance of the elastic member 31, so that the protruding portion 124 of the ring 12 can be relatively pressed against the hook claws 23, thereby making the first pipe diameter joint member 11 firmly fixed. The valve 14 in the connecting pipe 134 is relatively pushed away from the end of the connecting pipe 134 by the water inlet 51 of the water supply device, so that the connecting pipe 134 is in a conducting state, so that the water source entering the second pipe joint 41 through the water injection pipeline 61 can pass through the filtration of the filter element 44, and then enter the connecting pipe 134 and the connecting hole 131 of the first pipe joint 11 through the channel 423 in sequence, and finally enter the water inlet 51 of the water supply device to provide pure drinking water.

Furthermore, when the water injection line connector 10 provided by the present invention is to be disassembled from the water inlet end 51 of the water supply device, as shown in FIG. 5 , the user only needs to directly push the collar 12 by hand to compress the elastic member 31, so that the collar 12 can move axially relative to the joint 13, and then when the protruding portion 124 is no longer pressed against the hooks 23, the clamping state of the first pipe diameter joint 11 can be released. Then, the user only needs to directly pull out the water injection line connector 10 provided by the present invention to quickly complete the work of disassembling the water injection line 61, which is beneficial to the subsequent cleaning of the water supply device, and the water injection line provided by the present invention can be easily removed. During the process of the connector 10 being pulled out, the water inlet end 51 of the water supply device will be relatively pulled away from the connecting hole 131 of the first pipe diameter connector 11 and will not push the valve 14 located in the connecting pipe 134. At this time, the water pressure continuously input through the water injection pipeline 61 and the joint 431 will push the valve 14 in the opposite direction, so that the valve 14 will relatively close the port of the connecting pipe 134, and the connecting pipe 134 can be automatically put into a water-stopping state without closing the water source separately. In this way, the water injection pipeline connector 10 provided by the invention not only has the effect of quick assembly and disassembly, but also can provide a reliable water-stopping effect when dismantling. Please continue to refer to Figure 6. The water injection pipeline connector 10 provided by the present invention can also be assembled on each water outlet 631 of the water injection branch pipeline 63. By connecting the water injection pipeline connector 10 provided by the present invention to each water outlet 631 of the water injection branch pipeline 63, each water outlet 631 can not only be quickly connected to the required water supply device to provide additional filtering function, but also during use, if part of the water supply device must be detached from the corresponding water outlet 631 (for example, when it needs to be cleaned or repaired), the water injection pipeline connector 10 of the present invention also has the function of providing a reliable water stop in the detached state. Therefore, even if part of the water outlet 631 is detached from the corresponding water supply device, it will not affect the normal use of other water supply devices, and it is very practical.

As shown in FIGS. 4 and 7, the second diameter joint member 41 is provided with a second valve member 433 in the joint member 431 formed by the outward extension of the other end of the barrel 43. The second valve member 433 is used to control the conduction state between the joint member 431 and the inside of the barrel 43. When the filter element 44 is assembled in the barrel 43, the filter element 44 will push against the second valve member 433 to make the joint member 431 and the inside of the barrel 43 in a conduction state. Through this structure, when the filter element 44 in the barrel 43 of the second diameter joint member 41 needs to be replaced, the user only needs to replace the second diameter joint member 41. By removing the cover 42 of the component 41 from the barrel 43 and directly taking out the filter element 44 from the barrel 43, the pushing restriction of the filter element 44 on the second valve component 433 can be released. At this time, the water pressure continuously input through the water injection pipeline 61 pushes the second valve component 433 in the reverse direction, so that the second valve component 433 can relatively close the port of the joint 431, and thereby automatically generate a water-stopping effect without shutting off the water source separately, so that the water injection pipeline connector 10 provided by the present invention can provide a reliable water-stopping effect when replacing the filter element 44, thereby greatly improving the convenience of replacing the filter element 44. However, the disclosure of the above embodiments is only used to illustrate the present invention, and is not used to limit the present invention. Any replacement of equivalent components should still fall within the scope of the present invention.

In summary, those familiar with the technology in this field can understand that this creation can indeed achieve the above-mentioned purpose and has actually complied with the provisions of the Patent Law, so an application is filed in accordance with the law.
