Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically a faucet designed to prevent accidental opening. 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] The prior art disclosure number CN217130492U discloses a faucet designed to prevent accidental opening, including a water outlet pipe, a faucet base, and a rotary valve core placed inside the faucet base. The outer surface of the faucet base has a stepped groove. The upper end of the stepped groove has a handle connected to the valve core, and the lower end has a press-lock assembly. The press-lock assembly includes a press plate and a spring switch. The outer side of the non-moving end of the spring switch is fixed inside the stepped groove. The press plate is snapped into the lower end of the stepped groove and fixed to the moving end of the spring switch. The press plate works in conjunction with the spring switch and can move horizontally within the stepped groove as the moving end of the spring switch moves. When the press plate has no relative movement, the handle is in a safety locked state. When the press plate is pressed, the spring switch is locked, and the handle can be rotated to open the faucet. This utility model places the press-lock assembly inside the faucet base, resulting in an aesthetically pleasing design and convenient use.

[0004] With the above configuration, the existing faucet, through its self-locking structure, allows the press plate and spring switch to move horizontally within a stepped groove. When the press plate is pressed, the spring switch locks itself, allowing the handle to rotate freely to open the faucet. When water is no longer needed, the handle rotates back to its original position, and pressing the press plate again causes the spring switch to reset the press plate, making it flush with the side of the faucet base. At this point, the handle is in a safe locked state. However, the existing faucet design has the following drawbacks during operation:

[0005] The faucet described in the prior art requires pressing a pressure plate to use it, but after use, the pressure plate needs to be pressed again to lock the faucet via a spring switch. Most people forget to press the pressure plate again after use to turn the handle, and simply turn the handle and walk away. In this case, the faucet is not locked to turn off the water, resulting in water waste. Utility Model Content

[0006] This utility model aims to provide a faucet that prevents accidental activation. It mainly addresses the technical problem that, after using the faucet, most people forget to press the pressure plate and turn the handle again, only resetting the handle without locking the faucet, which easily leads to water waste.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A faucet designed to prevent accidental opening includes a water outlet pipe and a faucet base. The water outlet pipe is fixedly connected to the upper surface of the faucet base. A valve core is installed inside the faucet base and is connected to the water outlet pipe. An annular cavity is formed on one side of the faucet base. Symmetrical snap-fit ​​grooves are formed on the inner wall of the annular cavity. A sliding groove and a compression groove are formed on the bottom surface of the annular cavity. A valve stem is installed inside the valve core. A handle is rotatably connected to the inner wall of the annular cavity. A valve cylinder is fixedly connected to one end of the handle. The valve cylinder is sleeved on the outer wall of the valve stem and is slidably connected to the sliding groove. A protective component is installed inside the compression groove.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When the faucet needs to be used, first press the handle to move the protective component, causing the locking block to disengage from the locking groove. Then turn the handle to rotate the valve stem, which in turn drives the valve core to deliver water to the outlet pipe. After use, push the handle upward to reset the handle under the action of the protective component.

[0011] 2. Beneficial effects:

[0012] This solution incorporates an annular cavity, a snap-fit ​​groove, a valve stem, a handle, and a protective assembly. Pressing the handle causes the protective plate on the protective assembly to compress the compression ring, which in turn compresses the spring. At this point, the snap-fit ​​block disengages from the snap-fit ​​groove. Rotating the handle then causes the valve cylinder to rotate via the protective plate, which in turn rotates the valve stem, allowing water to flow. Turning the handle back to its original position causes the snap-fit ​​block to engage with the snap-fit ​​groove under the pressure of the compression spring. This effectively prevents forgetting to turn off the water. After use, simply turning the handle is all that's needed, making it very convenient. It also prevents accidental handle contact that could cause the valve core to jam, resulting in water waste.

[0013] Preferably, the protective component includes a compression ring that is slidably connected to the inner wall of the compression groove. One end of the compression ring is fixedly connected to a compression spring, and the other end of the compression spring is fixedly connected to the compression groove. A protective plate is rotatably connected to the other end of the compression ring. The other side of the protective plate is fixedly connected to the handle. Symmetrical locking blocks are fixedly connected to one side of the protective plate near the handle, and these locking blocks engage with locking grooves. By providing this protective component, the faucet can be protected, preventing it from being turned on without pressing the handle.

[0014] Preferably, one side of the protective plate near the compression ring has an annular groove, and a first ball bearing is rotatably connected to the inner wall of the groove. This reduces the friction between the protective plate and the annular cavity.

[0015] Preferably, a groove is formed on the side of the snap-fit ​​block away from the protective plate, and a second rotating ball is rotatably connected to the inner wall of the groove, with the second rotating ball contacting the snap-fit ​​groove. This reduces the friction between the snap-fit ​​block and the annular cavity.

[0016] Preferably, a baffle is fixed to the outer wall of the faucet base near the handle. The baffle allows the handle to be pushed and moved after use, preventing excessive movement of the handle and ensuring that the locking block can be properly inserted into the locking groove.

[0017] Preferably, a limiting plate is fixed to the outer wall of the faucet base. By setting the limiting plate, it is possible to prevent the handle from being opened excessively.

[0018] Preferably, both the valve stem and the valve cylinder are convex in shape, and the valve stem and valve cylinder are matched. This allows the valve cylinder to drive the valve stem to move, facilitating the opening of the valve core. Attached Figure Description

[0025] like Figure 1-4 As shown, a faucet designed to prevent accidental opening includes a water outlet pipe 1 and a faucet base 2. The water outlet pipe 1 is fixedly connected to the upper surface of the faucet base 2. A valve core 3 is installed inside the faucet base 2 and is connected to the water outlet pipe 1. An annular cavity 4 is provided on one side of the faucet base 2. Symmetrical snap-fit ​​grooves 5 are provided on the inner wall of the annular cavity 4. A sliding groove 6 and a compression groove 7 are provided on the bottom surface of the annular cavity 4. A valve stem 8 is installed inside the valve core 3. A handle 9 is rotatably connected to the inner wall of the annular cavity 4. A valve cylinder 10 is fixedly connected to one end of the handle 9. The valve cylinder 10 is sleeved on the outer wall of the valve stem 8 and is slidably connected to the sliding groove 6. A baffle 19 is fixedly connected to the outer wall of the faucet base 2 near the handle 9. A limiting plate 20 is fixedly connected to the outer wall of the faucet base 2.

[0026] More specifically, the valve cylinder 10 and handle 9 are designed so that when the faucet needs to be used, the handle 9 needs to be pressed first to release the limit on the handle 9, and then the handle 9 can be turned for easy use. The baffle 19 and the limiting plate 20 are designed so that the baffle 19 can block the handle 9 to prevent the handle 9 from being unable to be limited, and the limiting plate 20 can prevent the water flow from being too large.

[0027] The compression groove 7 is equipped with a protective component, which includes a compression ring 11. The compression ring 11 is slidably connected to the inner wall of the compression groove 7. One end of the compression ring 11 is fixedly connected to a compression spring 12. The other end of the compression spring 12 is fixedly connected to the compression groove 7. The other end of the compression ring 11 is rotatably connected to a protective plate 13. The other side of the protective plate 13 is fixedly connected to the handle 9. One side of the protective plate 13 is fixedly connected to a symmetrical snap-fit ​​block 14 near the handle 9. The snap-fit ​​block 14 snaps into the snap-fit ​​groove 5.

[0028] More specifically, through the protective component, the protective plate 13 on the protective component can drive the snap-fit ​​block 14 to insert or disengage from the snap-fit ​​groove 5. When the snap-fit ​​block 14 is inserted into the snap-fit ​​groove 5, it can protect the faucet. When the snap-fit ​​block 14 is disengaged from the snap-fit ​​groove 5, the faucet can be used by turning the handle 9.

[0029] A circular groove 15 is provided on one side of the protective plate 13 near the compression ring 11, and a first rotating ball 16 is rotatably connected to the inner wall of the groove 15.

[0030] More specifically, this reduces the friction between the protective plate 13 and the annular cavity 4.

[0031] The side of the snap-fit ​​block 14 away from the protective plate 13 has a rotating groove 17. The inner wall of the rotating groove 17 is rotatably connected to a second rotating ball 18, which is in contact with the snap-fit ​​groove 5.

[0032] More specifically, this reduces the friction between the snap-fit ​​block 14 and the annular cavity 4.

[0033] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0034] When the faucet needs to be used, first press the handle 9, causing the handle 9 to slide the protective plate 13 inside the annular cavity 4. This causes the protective plate 13 to push the compression ring 11 to move, causing the compression ring 11 to squeeze the compression spring 12. This causes the valve cylinder 10 to slide inside the slide groove 6 and engage with the valve stem 8. At this time, the protective plate 13 causes the locking block 14 to disengage from the locking groove 5. Then, rotate the handle 9, causing the handle 9 to rotate the protective plate 13. The protective plate 13 then rotates the valve cylinder 10 and the valve stem 8, causing the valve stem 8 to open the valve core 3. When the handle 9 abuts against the limiting plate 20, the water flow is at its maximum. After use, push the handle 9 to move, causing the valve stem 8 to close the water flow with the valve core 3. When one side of the handle 9 abuts against the baffle 19, the locking block 14 is inserted into the locking groove 5 under the action of the rebound force of the compression spring 12. Then, release the handle 9 to complete the use.

[0035] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.
