Description

Technical Field

[0001] This utility model belongs to the field of faucet technology and relates to an improved faucet. Background Technology

[0002] Faucets are ubiquitous water control devices in modern buildings. Some existing faucets are usually connected to multiple water outlet devices, such as shower heads, faucets, and spray nozzles. During long-term use, these water outlet devices often accumulate impurities that can pollute tap water. When the faucet is turned off, because there is still tap water remaining in the water outlet devices, the water pressure at the outlet end of the faucet is likely to be higher than the water pressure at the inlet end. This can lead to backflow of tap water into the water outlet devices and faucet. During the backflow, the tap water may carry the impurities attached to the water outlet devices into the inlet end, ultimately causing contamination of the tap water. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an improved faucet with filtration and backflow prevention functions.

[0004] The objective of this utility model can be achieved through the following technical solution: An improved faucet includes a faucet body, which has an inlet pipe and an outlet pipe. A valve core is disposed within the faucet body, and a valve stem is connected to the valve core to control its up and down movement. The faucet body has a fixing part with a water passage hole. The front end of the valve core passes through the fixing part and is a closed structure. A water inlet is provided on the side wall of the front end of the valve core. A check valve assembly is disposed within the valve core, comprising a check element, a sliding part, a connecting rod, and a connecting spring. The valve core has a water passage connected to the outlet pipe. A sliding groove is provided within the valve core for the sliding part to slide. A filter screen for filtration is fixedly disposed at the front end of the sliding part.

[0005] In the aforementioned improved faucet, the check valve is located inside the valve core and is connected to the sliding part inside the valve core via a connecting rod. The connecting spring is sleeved on the connecting rod, and the sliding part returns to its original position through the action of the connecting spring.

[0006] Compared with existing technologies, this improved faucet has improved the valve core structure by installing a check valve component inside the valve core and a filter screen at the front end of the sliding part, so that the valve core has the effects of filtering and check valve.

[0009] In the diagram, 1. Faucet body; 2. Inlet pipe; 3. Outlet pipe; 4. Valve core; 5. Valve stem; 6. Fixing part; 7. Check valve assembly; 8. Check valve component; 9. Sliding part; 10. Connecting rod; 11. Connecting spring; 12. Water passage; 13. Filter screen. Detailed Implementation

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0011] like Figure 1 , Figure 2 As shown, this improved faucet includes a faucet body 1, which has an inlet pipe 2 and an outlet pipe 3. A valve core 4 is installed inside the faucet body 1, and a valve stem 5 is connected to the valve core 4 to control its up-and-down movement. A fixing part 6 is installed inside the faucet body 1, and a water passage hole is provided on the fixing part 6. The front end of the valve core 4 passes through the fixing part 6 and is a closed structure. A water inlet is provided on the side wall of the front end of the valve core 4. A check valve assembly 7 is installed inside the valve core 4, consisting of a check valve 8, a sliding part 9, a connecting rod 10, and a connecting spring 11. A water passage 12 connected to the outlet pipe 3 is provided inside the valve core 4. A sliding groove is provided inside the valve core 4 for the sliding part 9 to slide. A filter screen 13 for filtering is fixedly installed at the front end of the sliding part 9.

[0012] To elaborate further on the flow of liquid, by rotating the valve stem 5, the valve core 4 is lowered, extending the water outlet out of the fixed part 6. Liquid flows into the valve core 4, and the water pressure pushes the sliding part 9 upward, compressing the return spring and causing the check element 8 to move upward. At this time, the valve core 4 is in the water-passing state. When the valve stem 5 is rotated, the valve core 4 rises, re-closing the water outlet. The sliding part 9 is no longer under pressure, the return spring rebounds, and the sliding part 9 returns to its original position. The check element 8 returns to its original position, and the valve core 4 is in the closed state.

[0013] To elaborate further, when the liquid passes through the sliding part 9, it can be filtered by the filter screen 13 at the front end of the sliding part 9 to remove impurities, thus giving the valve a filtering effect.

[0014] To elaborate further, the check valve 8 is located inside the valve core 4 and is connected to the sliding part 9 inside the valve core 4 via the connecting rod 10. The connecting spring 11 is sleeved on the connecting rod 10, and the sliding part 9 returns to its original position through the action of the connecting spring 11.

[0015] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0016] Although this document frequently uses terms such as faucet body 1, inlet pipe 2, outlet pipe 3, valve core 4, valve stem 5, fixing part 6, check valve assembly 7, check valve element 8, sliding part 9, connecting rod 10, connecting spring 11, water passage 12, and filter screen 13, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.
