Description

Water control valve with hook structure

The present invention relates to a valve for controlling water flow interruption or changing flow rate; in particular, it relates to an innovative structural type of a water control valve with a hook structure.

A water control valve is a kind of water control valve used to control the water flow or change the water flow rate. It is often seen in the application of water spray guns or other devices.

Patent document US11719346 discloses a water control valve, comprising a main body, a valve core and a dial control, wherein a through-flow groove is formed inside the main body, and the through-flow groove extends to the outside of the main body to form a water inlet and a water outlet. The valve core is arranged in the through-flow groove, and the valve core can be a sphere or a cylinder. The valve core can be in the through-flow groove. The valve core passes through a channel when the valve core rotates inwardly. The dial control has two legs, two shafts and a bridge portion. Each leg is adjacent to two sides of the exterior of the main body respectively. Each shaft is connected to each leg respectively. Each shaft is coaxially opposed to each other. Each shaft penetrates into the main body and is connected to the valve core respectively. Two ends of the bridge portion are connected to each leg respectively.

The bridge part is operated to rotate around the main body according to the axis of each shaft rod. The bridge part drives the valve core to rotate according to the axis of each shaft rod through each shaft rod, thereby changing the relative position of the channel and the flow groove in space, controlling whether the channel is connected to the flow groove or not, thereby controlling whether water flows through the valve core. When the channel is connected to the flow groove, the bridge part is operated to rotate, which can also change the radial area of the channel and the flow groove connected to each other, thereby changing the flow rate of water flowing through the channel and the flow groove.

In order to make the valve core easily inserted into the flow groove and the dial control unit easily connected to the valve core through the shafts, the main body and the dial control unit are selected to be pre-formed with a plurality of different components. When the assembly process is subsequently performed, the main body and the dial control unit are combined in conjunction with the valve core, making the specific structure of the known water control valve complex and the assembly process cumbersome.

The main purpose of the present invention is to provide a water control valve with a hook structure. The technical problem it aims to solve is to explore and innovate a new water control valve that is more ideal and practical.

Based on the above purpose, the technical features of the present invention for solving the problem mainly lie in the water control valve with a hook structure, including:

A valve shell, the valve shell has a first end and a second end along the axial direction, a chamber is formed inside the valve shell, the chamber extends to the first end, a through hole is formed at the second end to connect with the chamber, and a water inlet and a water outlet are formed along the radial direction of the valve shell to connect with the chamber respectively;

A valve core is axially arranged in the chamber, and the valve core passes through a channel, and two ends of the channel extend to the radial outside of the valve core respectively, so that the water inlet and the water outlet can be connected through the channel;

An operating member is connected to the valve core, and the operating member has an operating portion, and the valve core is operated to reciprocate and rotate, thereby controlling the communication relationship between the channel and the water inlet and the water outlet;

A hook structure is connected to one axial end of the valve core, and the hook structure abuts against the second end through the through hole, thereby limiting the axial positioning of the valve core.

The overall structure of the present invention and the process of arranging the valve core assembly on the valve housing are simplified, and the process of arranging the valve core assembly on the valve housing is easy to perform.

The drawings show an embodiment of the water control valve with a hooking structure of the present invention, but these embodiments are for illustrative purposes only and are not limited to this structure in patent applications.

As shown in Figures 1 to 6, the first embodiment of the water control valve with a hooking structure includes a valve shell 10, a valve core 20, an operating member 30 and a hooking structure 40, wherein the valve shell 10 has a first end 11 and a second end 12 along the axial direction, and a chamber 13 is formed inside the valve shell 10, and the chamber 13 extends to the first end 11, and a through hole 14 is formed at the second end 12 to connect to the chamber 13, and the valve shell 10 forms a water inlet 15 and a water outlet 16 along the radial direction to connect to the chamber 13 respectively.

The valve core 20 is axially disposed in the chamber 13 , and passes through a channel 21 . Both ends of the channel 21 extend radially outward of the valve core 20 , respectively, so that the water inlet 15 and the water outlet 16 are connected through the channel 21 .

The operating member 30 is connected to the valve core 20 . The operating member 30 has an operating portion 31 . The operating portion 31 is controlled to operate the valve core 20 to reciprocate, thereby controlling the communication relationship between the channel 21 and the water inlet 15 and the water outlet 16 .

The hook structure 40 is connected to one axial end of the valve core 20 , and the hook structure 40 abuts against the second end 12 through the through hole 14 , thereby limiting the axial positioning of the valve core 20 , so that the valve core 20 can remain disposed in the chamber 13 , and prevent the valve core 20 from leaving the chamber 13 through the first end 11 .

The valve housing 10 is selectively connected to a first connecting pipe 52 and a second connecting pipe 54, wherein the first connecting pipe 52 is connected to the water inlet 15, and the second connecting pipe 54 is connected to the water outlet 16. Accordingly, in the first embodiment, the first connecting pipe 52 can be connected to a water source end (not shown), and the second connecting pipe 54 can be connected to a water use end (not shown).

The valve core 20 is arranged in the outer space of the valve housing 10 and opposite to the containing chamber 13, and one end of the valve core 20 connected to the hook structure 40 faces the first end 11, the valve core 20 is moved to enter the containing chamber 13, and the valve core 20 is pressed away from one end of the hook structure 40, forcing the hook structure 40 to further protrude from the containing chamber 13 through the through hole 14 to the outside of the valve housing 10 and abut against the second end 12, the hook structure 40 is hooked to the valve housing 10, and the second end 12 forms an obstruction to the hook structure 40, limiting the axial positioning of the valve core 20, and completing the operation of assembling the valve core 20 on the valve housing 10.

As shown in Figures 4 and 5, when the two ends of the channel 21 are connected to the water inlet 15 and the water outlet 16 respectively, water can flow from the first connecting pipe 52 through the water inlet 15, the channel 21 and the water outlet 16 in sequence into the second connecting pipe 54. As shown in Figure 6, the operating part 31 is controlled so that the operating member 30 drives the valve core 20 to rotate, so that the channel 21 is not connected to the water inlet 15 and the water outlet 16, and the valve core 20 blocks the connection between the water inlet 15 and the water outlet 16.

Compared with the prior art, the overall structure of the first embodiment and the process of assembling the valve core 20 to the valve housing 10 are simplified, and the process of assembling the valve core 20 to the valve housing 10 is easy to perform.

The hook structure 40 includes two hooks 42, each of which is laterally opposite to each other and forms a gap 44 therebetween. Each of the hooks 42 includes a connecting portion 422 and a supporting portion 424. Each of the connecting portions 422 is connected to the valve core 20 and is located in the through hole 14. Each of the supporting portions 424 is connected to each of the connecting portions 422, and each of the supporting portions 424 is against the second end 12.

When the valve core 20 is assembled in the valve housing 10, the hook structure 40 enters the chamber 13 and moves toward the through hole 14. Each of the hooks 42 is respectively pressed by the valve housing 10. The gap 44 allows each of the abutting portions 424 to be relatively close to each other and protrude from the outside of the valve housing 10 through the through hole 14. Each of the abutting portions 424 then moves away from each other in the opposite direction and abuts against the second end 12 respectively. The second end 12 restricts each of the abutting portions 424. Each of the abutting portions 424 cannot easily pass through the through hole 14 into the chamber 13, thereby limiting the axial positioning of the valve core 20.

Specifically, each of the abutting portions 424 forms a slope 426, whereby, during the process of assembling the valve core 20 in the valve housing 10, each of the slopes 426 can guide each of the abutting portions 424 to be relatively close to each other, so that each of the abutting portions 424 can more easily enter the through hole 14, which is a better implementation choice.

The valve housing 10 forms a long groove 17 connecting the chamber 13 and the outer portion of the valve housing 10 along its radial direction. The long groove 17 extends in a direction toward the water inlet 15 and the water outlet 16. The valve housing 10 forms a stopper on the side of the long groove 17 facing the first end 11 and the second end 12.

The valve core 20 forms two slide grooves 22 laterally opposite to each other, and each of the slide grooves 22 extends to one end of the valve core 20 to form the hook structure 40. The operating member 30 further includes two slide blocks 32 respectively coupled to the operating portion 31, and each of the slide blocks 32 is slidably inserted into each of the slide grooves 22. The operating portion 31 extends to the outside of the valve housing 10 through the long slot 17.

When the valve core 20 is assembled in the valve housing 10, the operating member 30 is first inserted into the chamber 13 through the long slot 17, and each of the slide blocks 32 enters the chamber 13 respectively, and the operating portion 31 protrudes from the outside of the valve housing 10 through the long slot 17. Then, during the process of the valve core 20 entering the chamber 13 through the first end 11, each of the slide blocks 32 slides into each of the slide blocks 32. The slide groove 22 connects the valve core 20 and the operating member 30 by means of the slide blocks 32 and the slide grooves 22. The valve housing 10 forms a stopper for the operating portion 31 in the direction facing the first end 11 and the second end 12. Accordingly, the operating member 30 is operated to move the operating portion 31 along the elongated extension direction of the long groove 17, thereby controlling the valve core 20 to rotate.

The valve housing 10 does not need to cooperate with the operating portion 31 protruding from the valve housing 10 on the path of the reciprocating movement of the operating portion 31 to form avoidance or retraction. Compared with the prior art, the operating member 30 will not limit the variability of the external shape of the valve housing 10.

The operating portion 31 includes two side pieces 33, each of which is laterally opposite to each other, and each of the sliders 32 is coupled to each of the side pieces 33. The operating member 30 further includes two connecting pieces 34, each of which is connected to each of the side pieces 33, and each of the sliders 32 is connected to each of the connecting pieces 34, so that each of the sliders 32 is coupled to the operating portion 31 through each of the connecting pieces 34. The operating portion 31 optionally has a middle piece 35 connected to each of the side pieces 33.

The side pieces 33 that are laterally opposite to each other can be elastically deformed laterally, respectively, so as to provide elastic forces respectively, so as to enable the slide blocks 32 to clamp the valve core 20 relative to each other.

The figure shows that each of the side panels 33 is a straight sheet. Each of the side panels 33 can be replaced with an arc-shaped sheet, thereby forming a replacement embodiment not shown in the figure.

In this example, each of the connecting pieces 34 is arc-shaped and can be elastically deformed to provide elastic force, so as to enable each of the sliding blocks 32 to clamp the valve core 20 relative to each other.

In conjunction with the arc-shaped connecting pieces 34, the operating portion 31 can be simply replaced with a columnar structure or a frame structure, thereby forming another replacement embodiment and yet another replacement embodiment not shown in the drawings.

The valve core 20 is radially expanded at one end thereof axially away from the hook structure 40 to form a ring portion 23. The ring portion 23 radially corresponds to the radial portion of the valve housing 10 surrounding the chamber 13, thereby causing the valve core 20 to be centered inside the chamber 13. When the hook structure 40 is hooked to the valve housing 10, it helps to avoid possible deflection of the valve core 20.

Two first leak-proof rings 62 are embedded on one side of the valve housing 10 facing the chamber 13. Each of the first leak-proof rings 62 surrounds the water inlet 15 and the water outlet 16 respectively. The radial periphery of the valve core 20 presses each of the first leak-proof rings 62. Accordingly, water flows through the water inlet 15, the channel 21 and the water outlet 16. Each of the first leak-proof rings 62 can prevent water from leaking to both sides of the flow direction.

The formation of the ring portion 23 can further promote each of the first anti-leakage rings 62 to bear the same force from the valve housing 10 and the valve core 20, which helps to improve the effect of preventing water leakage.

Two second anti-leakage rings 64 are embedded in the inner side of the valve housing 10 facing the chamber 13. Each of the second anti-leakage rings 64 surrounds each of the first anti-leakage rings 62. The radial outer periphery of the valve core 20 presses each of the second anti-leakage rings 64.

As shown in FIG. 6 , the second anti-leakage rings 64 are disposed so that when the valve core 20 rotates and the channel 21 is not connected to the water inlet 15 and the water outlet 16 , the two ends of the channel 21 are able to correspond to between the first anti-leakage rings 62 and the second anti-leakage rings 64 .

As shown in FIG. 7 and FIG. 8 , the structure of the second embodiment is mainly different from that of the first embodiment in that each of the slide grooves 22 is mainly composed of a first groove section 222 and a second groove section 224 connected to each other, each of the first groove sections 222 extends to one end of the valve core 20, each of the second groove sections 224 is closed at one end far away from each of the first groove sections 222, the distance between each of the first groove sections 222 is greater than the distance between each of the slide blocks 32, and the distance between each of the second groove sections 224 is less than the distance between each of the first groove sections 222.

The operating member 30 is deformed so that each slider 32 can move away from the opposite direction and slide into each first slot section 222. Then, each slider 32 slides along each first slot section 222 and enters each second slot section 224. The elastic restoring force of the deformed operating member 30 causes each slider 32 to move closer to each other and clamp the valve core 20. At this time, the valve core 2 0 constitutes the portion where each second groove section 224 is connected to each first groove section 222, and forms a stop for each slide block 32, so that each slide block 32 is difficult to slide reversely from each second groove section 224 into each first groove section 222 without external force operation control, thereby indirectly further improving the stability of the combination of the valve core 20 and the valve housing 10.

As shown in Figures 9 and 10, the structure of the third embodiment is mainly different from that of the second embodiment in that the valve core 20 is further formed with two guide portions 24, each of the guide portions 24 is respectively formed with a groove wall on the side of each first groove section 222 facing the direction of each connecting piece 34, each of the guide portions 24 is respectively formed with an oblique guide edge 242 on the side away from the operating portion 31, and the distance between each of the guide edges 242 increases from each of the first groove sections 222 extending to one end of the valve core 20 toward the direction where each of the first groove sections 222 connects to one end of each of the second groove sections 224.

When each slider 32 slides into each chute 22, each guide edge 242 pushes against each connecting piece 34, thereby guiding each connecting piece 34 or each side piece 33 to elastically deform, so that each slider 32 can move away from the opposite direction and slide into each first slot section 222, and then when each slider 32 enters each second slot section 224, each slider 32 approaches each other to clamp the valve core 20.

The distance between each first groove section 222 increases from one end of each first groove section 222 away from each second groove section 224 toward each second groove section 224. Accordingly, in the process of each slider 32 sliding through each first groove section 222 and entering each second groove section 224, the valve core 20 is located between each first groove section 222 to form a portion with increasing width, which can also guide each slider 32 to gradually move away in the opposite direction.

By selecting the size of the distance between each guide edge 242 and the distance between each first groove section 222, the second embodiment can choose to use each guide edge 242 to guide each slider 32, or can choose to use the portion of the valve core 20 located between each first groove section 222 to guide each slider 32, or can choose to use both each guide edge 242 and the portion of the valve core 20 located between each first groove section 222 to guide each slider 32.
