Description

Technical Field

[0001] This invention relates to the field of faucet technology, and more particularly to a pressure-bearing faucet. Background Technology

[0002] A faucet is a common name for a water valve, used to control the flow of water and thus saving water. Faucets are constantly being updated and replaced, evolving from old-fashioned cast iron faucets to electroplated knob faucets, and then to stainless steel single-temperature single-control faucets, stainless steel dual-temperature dual-control faucets, and semi-automatic kitchen faucets.

[0003] Although faucets are updated and replaced quickly, and come in a wide variety of types and functions, existing faucets often cannot withstand the impact of high water pressure. To prevent faucets from leaking or being damaged due to high water pressure, existing faucets generally need to first transfer the water source to a water pressure buffer device (such as a transfer storage tank) to reduce the water pressure before the buffered water source is discharged through a pipe connected to the water pressure buffer device. This overcomes the problem that faucets cannot withstand high water pressure, but this makes the faucet easy to be limited by the water supply pressure when in use, which not only limits its applicable range, but also leads to additional costs and workload. Summary of the Invention

[0004] Therefore, it is necessary to provide faucets with simple structures that can withstand greater water pressure in order to expand the faucet's applicability.

[0005] This invention provides a pressure-bearing faucet, the faucet comprising:

[0006] The valve body includes an inlet pipe section and an outlet pipe section, the inlet pipe section being connected to the outlet pipe section, wherein the inlet pipe section is provided with a first stop section;

[0007] A valve core assembly includes a valve core and a first seal. The valve core includes a stop portion and a drive portion. The first seal is sleeved on the stop portion. The drive portion passes through the first stop portion and extends at least partially to the outlet pipe portion. The valve core has an initial position and a drain position. When the valve core is in the initial position, the first seal abuts against the first stop portion and separates the inlet pipe portion from the outlet pipe portion. When the valve core is in the drain position, the first seal separates from the first stop portion.

[0008] A switch assembly includes a push rod disposed on the water outlet pipe. The push rod has a protrusion. When the protrusion abuts against the drive unit, the valve core is in the drain position.

[0009] Furthermore, the first stop portion is provided with a clearance hole, and the valve core also includes a first connecting portion. The first connecting portion is connected between the stop portion and the drive portion and is at least partially located in the clearance hole. The first connecting portion is provided with a clearance structure. When the valve core is in the drainage position, the water source flows to the water outlet pipe portion through the clearance structure.

[0010] Furthermore, the valve core assembly also includes a first reset member and a limiting member. The limiting member is fixed inside the water inlet pipe and located at one end away from the water outlet pipe. The two ends of the first reset member abut against the limiting member and the blocking part, respectively.

[0011] Furthermore, the valve core also includes a guide portion located at the end of the abutment portion away from the drive portion, wherein the limiting member has a guide hole corresponding to the guide portion, and the guide portion is at least partially inserted into the guide hole.

[0012] Furthermore, the valve core also includes two limiting arms, which are connected at a certain distance from the end of the drive unit away from the stop unit, and the push rod is at least partially restricted between the two limiting arms.

[0013] Furthermore, the driving part has a first inclined surface, and the protrusion has a second inclined surface. The slopes of the first inclined surface and the second inclined surface are the same. The amount of drainage flowing through the relief hole per unit time is controlled by changing the contact area between the first inclined surface and the second inclined surface.

[0014] Furthermore, the push rod also includes a guide rod portion and an adjustment portion. The adjustment portion is connected to the protrusion and extends out of the valve body. The guide rod portion is connected to the end of the protrusion away from the adjustment portion. The water outlet portion is provided with a second stop portion. The second stop portion is provided with a limiting water guide hole corresponding to the guide rod portion. When the protrusion abuts against the second stop portion, the valve core is in the initial position.

[0015] Furthermore, the water outlet pipe includes a water outlet end and a control end. The water outlet end is located at one end of the second stop portion away from the protrusion, and the control end is located at the other end of the water outlet pipe. The control end is used to install the switch assembly. The faucet also includes a valve cover, which is detachably connected to the control end. The push rod also includes a second connecting portion, which is located between the adjusting portion and the protrusion. The second connecting portion has an annular connecting groove. The switch assembly also includes a second sealing member, the inner ring of which is sealed and connected in the annular connecting groove, and the outer ring of which is sealed and connected between the valve cover and the control end.

[0016] Furthermore, the switch assembly also includes a second reset member, the two ends of which respectively abut against the valve cover and the second connecting portion.

[0017] Furthermore, a reinforcing rib connects the second stop portion to the water outlet pipe portion.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention achieves the opening and closing of the faucet by setting the first stop part in the water inlet pipe, sleeve the first sealing member on the abutment part of the valve core, passing the drive part through the first stop part and extending at least partially into the water outlet pipe, and setting the protrusion on the push rod to drive the drive part to move the valve core between the initial position and the drain position. When the valve core is in the initial position, the water pressure applied to the abutment part by the water source towards the first stop part causes the abutment part to always tend to move towards the first stop part, tightly squeezing the first sealing member between the abutment part and the first stop part. This allows the faucet to withstand greater water pressure, and as the water pressure increases, the force of the abutment part towards the first stop part will increase synchronously, thereby making the first sealing member seal more tightly between the abutment part and the first stop part.

[0035] Please see Figure 1 A pressure-bearing faucet 100 is characterized in that the faucet 100 includes a valve body 10, a valve core assembly 20 and a switch assembly 30, wherein the valve core assembly 20 is disposed inside the valve body 10, and the switch assembly 30 is used to drive the valve core assembly 20 to open to supply water or close to stop supplying water.

[0036] It should be noted that the water mentioned in this application can be any liquid (e.g., water source, oil, etc.), or a fluid or gas. For ease of description, water source will be used as the subject of this application.

[0037] The valve body 10 includes an inlet pipe section 11 and an outlet pipe section 12. The inlet pipe section 11 is connected to the outlet pipe section 12. The water source enters the valve body 10 through the inlet pipe section 11 and is discharged through the outlet pipe section 12.

[0038] In one embodiment, the valve body 10 is generally T-shaped, wherein the inlet pipe 11 may be vertically connected to the middle of the outlet pipe 12, or it may be connected to the middle of the outlet pipe 12 at other angles. Preferably, the inlet pipe 11 is vertically connected to the middle of the outlet pipe 12.

[0039] Please see Figure 2-7 The water inlet pipe 11 is provided with a first stop 111, which is used to stop the valve core assembly 20 so that when the water supply is stopped, the valve core assembly 20 can be tightly closed with the first stop 111 under the pressure of the water source and can withstand the force exerted on the valve core assembly 20 by the water source.

[0040] In one embodiment, the valve core assembly 20 includes a valve core 21 and a first seal 22. The first seal 22 is sleeved on the valve core 21 and is used to tightly abut against the first stop portion 111 when the water supply is stopped to isolate the water inlet pipe portion 11 from the water outlet pipe portion 12 to prevent the water source from flowing to the water outlet pipe portion 12.

[0041] Furthermore, the valve core 21 includes a stop portion 211 and a drive portion 212, the first sealing member 22 is sleeved on the stop portion 211, and the drive portion 212 passes through the first stop portion 111 and extends at least partially to the water outlet pipe portion 12.

[0042] The valve core 21 has an initial position and a drain position. When the valve core 21 is in the initial position, the first sealing member 22 abuts against the first stop part 111 and separates the water inlet pipe 11 from the water outlet pipe 12. That is, the first sealing member 22 is tightly pressed between the stop part 211 and the first stop part 111 under the force of the water source, so that the water source cannot flow to the water outlet pipe 12.

[0043] When the valve core 21 is in the drain position, the first seal 22 separates from the first stop 111, so that the water source can flow through the first stop 111 to the outlet pipe 12 to supply water.

[0044] Furthermore, the first stop portion 111 is provided with a clearance hole 1111, and the valve core 21 also includes a first connecting portion 213. The first connecting portion 213 is connected between the stop portion 211 and the drive portion 212 and is at least partially located in the clearance hole 1111. The first connecting portion 213 is provided with a clearance structure 2131. When the valve core 21 is in the drainage position, the water source flows to the water outlet pipe portion 12 through the clearance structure 2131.

[0045] Specifically, the abutment portion 211 is provided with an annular groove 2111, and the first sealing member 22 is embedded in the annular groove 2111. The cross-sectional area of ​​the end of the annular groove 2111 near the first connecting portion 213 is not greater than the cross-sectional area of ​​the relief hole 1111, while the cross-sectional area of ​​the end of the annular groove 2111 away from the first connecting portion 213 is greater than the area of ​​the relief hole 1111. That is, the cross-sectional area of ​​the abutment portion 211 is greater than the cross-sectional area of ​​the relief hole 1111. This allows the first sealing member 22 to be compressed and tightly connected between the abutment portion 211 and the first stop portion 111 when the valve core 21 moves towards the first stop portion 111 under the action of the water source.

[0046] Furthermore, the first stop portion 111 is also provided with an annular protrusion 1112 in the direction away from the water outlet portion 12. A relief groove 1113 is formed between the annular protrusion 1112 and the inner wall of the water inlet portion 11 at a certain distance. By providing the relief groove 1113, the first sealing member 22 can be at least partially deformed into the relief groove when subjected to a large force.

[0047] Furthermore, the first sealing element 22 is a sealing ring, which can be made of silicone or other materials and can be deformed by compression.

[0048] In one embodiment, along the movement direction of the valve core 21, the clearance structure 2131 can be an elongated drainage channel, wherein the length of the drainage channel is greater than the width of the first stop portion 111, so that when the valve core 21 is in the drainage position, the water source can flow through the drainage channel to the water outlet pipe portion 12.

[0049] In another embodiment, along the movement direction of the valve core 21, the clearance structure 2131 can also be an elongated drain hole, wherein the drain hole penetrates the first connecting portion 213, and the length of the drain hole is greater than the width of the first stop portion 111, so that when the valve core 21 is in the drain position, the water source can flow to the water outlet pipe portion 12 through the drain hole.

[0050] In other embodiments, the clearance structure 2131 may include both the drainage groove and the drainage hole.

[0051] Please see Figure 8-11 and combined Figure 1-7The switch assembly 30 includes a push rod 31, which is located on the water outlet pipe 12. The push rod 31 drives the valve core 21 to switch between the initial position and the drainage position by driving the drive unit 212. That is, the push rod 31 is used to control the faucet 100 to open to supply water or close to stop the water supply.

[0052] In one embodiment, the push rod 31 is provided with a protrusion 311, which is used to drive the drive unit 212 to switch the valve core 21 between the initial position and the drainage position.

[0053] When the protrusion 311 abuts against the drive part 212, the valve core 21 is in the drain position. When the position of the protrusion 311 and the drive part 212 abuts changes, the amount of water flowing through the relief structure 2131 will also change accordingly. That is, the water output of the faucet 100 can be adjusted and controlled by changing the position of the protrusion 311 and the drive part 212 abutting.

[0054] In one embodiment, the driving part 212 has a first inclined surface 2121 that is inclined downward, and the protrusion 311 has a second inclined surface 3111 that is inclined upward, wherein the first inclined surface 2121 and the second inclined surface 3111 have the same slope, so that the first inclined surface 2121 and the second inclined surface 3111 are in surface contact.

[0055] By changing the contact area between the first inclined surface 2121 and the second inclined surface 3111, the amount of drainage flowing through the relief hole 1111 per unit time can be controlled. At the same time, by making the first inclined surface 2121 and the second inclined surface 3111 in surface contact, the contact area between the push rod 31 and the valve core 21 can be relatively larger, so that the push rod 31 can drive the valve core 21 more stably.

[0056] As the contact area between the first inclined surface 2121 and the second inclined surface 3111 gradually decreases, the blocking part 211 gradually moves away from the first stop part 111, so that the drain hole and / or the drain groove can pass through the clearance hole 1111 more and be located in the water inlet pipe part 11, thereby gradually increasing the water supply.

[0057] As the contact area between the first inclined surface 2121 and the second inclined surface 3111 gradually increases, the blocking part 211 gradually moves closer to the first stop part 111, causing the portion of the drain hole and / or the drain groove that passes through the clearance hole 1111 and is located inside the water inlet pipe part 11 to gradually decrease, thereby gradually reducing the water supply.

[0058] In another embodiment, the drive unit 212 has a first inclined surface 2121, which is arranged obliquely downward. The protrusion 311 is a protrusion. The push rod 31 moves along its axial direction to change the position of the protrusion on the first inclined surface 2121, thereby driving the valve core 21 to the position of the water inlet pipe 11. This causes the position of the drain hole and / or the drain groove to change accordingly as it passes through the relief hole 1111 and extends into the water inlet pipe 11, thereby achieving control of the drainage volume.

[0059] Furthermore, the valve core assembly 20 also includes a first reset member 23 and a limiting member 24. The limiting member 24 is fixed inside the water inlet pipe 11 and located at one end away from the water outlet pipe 12. The two ends of the first reset member 23 respectively abut against the limiting member 24 and the blocking part 211.

[0060] By setting the limiting member 24 and the first reset member 23, the first reset member 23 can always provide a reset force to the valve core 21, so that the valve core 21 tends to move to the initial position.

[0061] Specifically, the main function of the first reset member 23 is to quickly drive the valve core 21 toward the water outlet pipe 12 when the water supply is stopped, so that the first seal member 22 is held between the stop part 211 and the first stop part 111.

[0062] It should be noted that the first reset member 23 may be, but is not limited to, a compression spring, a tower spring, or other elastic member that can both drive the valve core 21 to move toward the water outlet pipe 12 and allow the water source to pass through.

[0063] Furthermore, the valve core 21 also includes a guide portion 214, which is located at the end of the abutment portion 211 away from the drive portion 212. The limiting member 24 is provided with a guide hole 241 corresponding to the guide portion 214, and the guide portion 214 is at least partially inserted into the guide hole 241.

[0064] By setting the guide hole 241 and the guide portion 214, the valve core 21 can achieve dual guidance and limiting under the action of the relief hole 1111 and the guide hole 241, thereby ensuring that the valve core 21 can move stably along its axial direction. When the valve core 21 is in the initial position, the first sealing member 22 can be uniformly squeezed and tightly sealed between the abutment portion 211 and the first stop portion 111. This can reduce the friction between the valve core 21 and the relief hole 1111, improve the service life of the valve core 21, and prevent the first sealing member 22 from being easily damaged due to uneven force. This can simultaneously improve the service life of the first sealing member 22 and prevent water leakage.

[0065] In one embodiment, the guide portion is cylindrical, and the guide hole 241 is adapted to the outer surface of the guide portion 214. Along the direction of movement of the valve core 21, the limiting member 24 is provided with a plurality of water guide holes or water guide grooves 242, so that the limiting member 24 can not only support the first reset member 23 and limit and guide the guide portion 214, but also ensure that the water source can flow through the limiting member 24 to the blocking portion 211.

[0066] Furthermore, the inner side of the water inlet pipe 11 is provided with an annular stepped surface 112 corresponding to the limiting member 24. One end of the limiting member 24 abuts against the stepped surface 112. By setting the stepped surface 112, the limiting member 24 can be positioned and the limiting member 24 can also play a certain buffering role on the water source, avoiding the water source from directly impacting the blocking part 211, thereby reducing the force of the water source borne by the valve core 21.

[0067] Furthermore, the valve core 21 also includes two limiting arms 215, which are connected at a certain distance to one end of the drive part 212 away from the stop part 211, and the push rod 31 is at least partially restricted between the two limiting arms 215.

[0068] In one embodiment, the protrusion 311 is generally flat, and the two limiting arms 215 are respectively at least partially restricted on opposite sides of the protrusion 311. By setting the two limiting arms 215, not only can the push rod 31 be limited so that the push rod 31 is always restricted on the valve core 21, but the push rod 31 can also limit the valve core 21, further increasing the stability when the push rod 31 drives the valve core 21 to move.

[0069] Furthermore, the push rod 31 also includes a guide rod portion 312 and an adjustment portion 313. The adjustment portion 313 is connected to the protrusion 311 and extends out of the valve body 10. It is used to adjust the position of the push rod 31 in the water outlet pipe portion 12, thereby changing the position of the protrusion 311, and thus changing the position of the valve core 21 in the water inlet pipe portion 11 so that the valve core 21 switches between the initial position and the drainage position.

[0070] The guide rod portion 312 is connected to the end of the protrusion 311 away from the adjusting portion 313. The water outlet pipe portion 12 is provided with a second stop portion 121, which is used to stop the bottom end of the protrusion 311. When the protrusion 311 abuts against the second stop portion 121, the valve core 21 is in the initial position, and the driving portion 212 is separated from the protrusion 311.

[0071] Furthermore, the second stop portion 121 is provided with a limiting water guide hole 1211 corresponding to the guide rod portion 312, and the guide rod portion 312 passes through the limiting water guide hole 1211.

[0072] The guide rod 312 and the limiting water guide hole 1211 are provided with a gap 13 for the water source to flow through. When the valve core 21 is in the drainage position, the water source passes through the second stop part 121 through the gap 13.

[0073] Furthermore, a third sealing member 14 may be provided at the bottom end of the protrusion 311. When the protrusion 311 abuts against the second stop portion 121, the third sealing member 14 is squeezed and sealed between the protrusion 311 and the second stop portion 121, thereby preventing water droplets remaining in the water outlet pipe portion 12 from falling.

[0074] Furthermore, the water outlet pipe section 12 includes a water outlet end 122 and a control end 123. The water outlet end 122 is located at one end of the second stop portion 121 away from the protrusion 311, and the control end 123 is located at the other end of the water outlet pipe section 12. The control end 123 is used to install the switch assembly 30.

[0075] The faucet 100 also includes a valve cover 40, which is detachably connected to the control terminal 123, and the push rod 31 passes through the valve cover 40 so that the adjustment part 313 extends out of the valve body 10.

[0076] In one embodiment, the valve cover 40 is provided with an internal thread 41, and the control end 123 is provided with an external thread 1231 that is adapted to the internal thread 41, and the valve cover 40 is threadedly connected to the control end 123.

[0077] In another embodiment, the valve cover 40 and the control terminal 123 can also be detachably connected by tightening screws.

[0078] Furthermore, the push rod 31 also includes a second connecting portion 314, which is disposed between the adjusting portion 313 and the protrusion 311. The second connecting portion 314 has an annular connecting groove 3141. The switch assembly 30 also includes a second sealing member 32, the inner ring portion 321 of the second sealing member 32 is sealed and connected in the annular connecting groove 3141, and the outer ring portion 322 of the second sealing member 32 is sealed and connected between the valve cover 40 and the control end 123.

[0079] Specifically, the second connecting part 314 includes two annular limiting arms 3142, which are spaced a certain distance apart to form the annular connecting groove 3141, and the inner ring part 321 of the second sealing member 32 is embedded in the annular connecting groove 3141.

[0080] The inner surface of the valve cover 40 is provided with a first limiting ring 42, and a first limiting groove 43 is formed between the first limiting ring 42 and the internal thread 41. The second sealing member 32 also includes a first ring portion 323 connected between the outer ring portion 322 and the inner ring portion 321. When the second sealing member 32 is installed in the valve body 10, the first ring portion 323 is restricted between the first limiting ring 42 and the inner wall of the water outlet pipe portion 12 corresponding to the control end 123, and the outer ring portion 322 is pressed between the valve cover 40 and the end face of the control end 123.

[0081] By setting the annular connecting groove 3141 to seal the inner ring, and by setting the valve cover 40 to cooperate with the control end 123 to seal the outer ring and the first ring portion 323, the second sealing member 32 is sealed between the push rod 31 and the control end 123, thereby preventing the water source from leaking out from the control end 123 when water is supplied.

[0082] Furthermore, the switch assembly 30 also includes a second reset member 33, the two ends of which abut against the valve cover 40 and the second connecting portion 314 respectively.

[0083] Specifically, the inner surface of the valve cover 40 is also provided with a second limiting ring 44. The second limiting ring 44 is located inside the first limiting ring 42 and is spaced a certain distance from the first limiting ring 42 to form a second limiting groove 45. One end of the second reset member 33 abuts against the inner surface of the valve cover 40 and is limited in the second limiting groove 45. The other end of the second limiting member 24 abuts against the annular limiting arm 3142 near one end of the adjusting part 313.

[0084] Furthermore, the second reset member 33 may be, but is not limited to, a compression spring, disc spring, tower spring, metal spring, silicone sleeve, or other elastic member that can drive the push rod 31 to move toward the water outlet 122.
