[0036] Figure 1 FIG. 1 shows a basin faucet 100 in one embodiment of the present invention. Figure 1 and Figure 2 As shown, in one embodiment, the basin faucet 100 includes a water outlet body 101 and a valve assembly 102. The water outlet body 101 includes a flow channel 201, and the flow channel 201 includes a water inlet 202 and a water outlet 203 (such as Figure 4 ). The valve assembly 102 includes a valve seat 304 and a valve core 303. The valve core 303 can move relative to the valve seat 304 to switch between an open state and a closed state. When the valve core 303 is in the open state (as shown in FIG. Figure 6 As shown in FIG. 1 ), the water inlet 202 and the water outlet 203 are connected (directly or indirectly). Assuming that water enters the water outlet body 101 from the water inlet 202, the water outlet 203 can discharge water. Figure 5 or Figure 7 As shown in FIG. 1 , the water inlet 202 and the water outlet 203 are separated from each other, and the water outlet 203 of the water outlet body 101 cannot discharge water. The specific structure and working principle of the valve assembly 102 will be described below.

[0037] like Figure 2 As shown, the basin faucet 100 further includes a joint assembly 103, through which the water outlet body 101 and the valve assembly 102 are connected. The joint assembly 103 further includes a first joint 104 and a second joint 105, which are threadedly connected. Figure 2 As shown, the first joint 104 is provided with an external thread 502, and the second joint 105 is provided with an internal thread 501, and the external thread 502 and the internal thread 501 are connected to each other (interlocked). Alternatively, in other embodiments not shown in the figure, the first joint 104 is provided with an internal thread 501, and the second joint 105 is provided with an external thread 502. The second joint 105 is fixedly connected to the water outlet body 101, the first joint 104 is connected to the valve seat 304, the first joint 104 and the second joint 105 are threadedly connected, and at least one of the first joint 104 and the second joint 105 is made of metal. In the utility model, the joint is made of metal, which means that any part of the joint is made of metal. Accordingly, at least one of the external thread 502 and the internal thread 501 is made of metal.

[0038] In the prior art, a set of external threads and a set of internal threads used to achieve the connection between the water outlet body and the valve assembly are both made of plastic. The structural strength of the plastic threads themselves is not high, and the connection strength or locking force of the plastic threads is not high, which makes the valve assembly easy to loosen. For example, after a frozen basin faucet is thawed, the connection of the plastic threads is easy to loosen under the water pressure inside the flow channel, thereby causing the valve assembly to loosen, and may even cause water seepage at the plastic threads.

[0039] In the basin faucet 100 of the present invention, the internal thread 501 and the external thread 502 are used to achieve the connection between the water outlet body 101 and the valve assembly 102, and at least one of the two sets of threads is made of metal. Compared with plastic threads, metal threads have higher structural strength and connection strength. Therefore, the internal thread 501 and the external thread 502 of the joint assembly 103 of the present invention are connected more tightly, and the risk of the valve assembly 102 loosening relative to the water outlet body 101 is lower.

[0040] In some embodiments, in order to further improve the connection strength between the internal thread 501 and the external thread 502 and reduce the risk of loosening of the valve assembly 102, the first connector 104 and the second connector 105 can both be made of metal, that is, the internal thread 501 and the external thread 502 can both be made of metal.

[0041] In some embodiments, the material of the first connector 104 can be copper or stainless steel. Copper and stainless steel have good rust resistance, so the first connector 104 made of copper or stainless steel has a longer service life. Similarly, in order to improve the rust resistance and service life of the second connector 105, the second connector 105 can also be made of copper or stainless steel.

[0042] like Figure 2 As shown, in some embodiments, the water outlet body 101 includes an outer shell 106 and an inner core 107, the inner core 107 is arranged inside the outer shell 106, and the flow channel 201 is arranged inside the inner core 107. Among them, the inner core 107 is made of metal, and the outer shell 106 is made of plastic. Such a configuration can improve the rust resistance of the outer surface of the water outlet body 101. More specifically, the inner core 107 can be made of copper or stainless steel, and the outer shell 106 can be made of ABS (Acrylonitrile Butadiene Styrene), PVC (Polyvinyl chloride) or other types of plastics. In other embodiments, the water outlet body 101 may also only include the inner core 107. As shown Figure 4 As shown, in some embodiments, the water outlet body 101 may further include a water outlet nozzle 108 , and the water outlet nozzle 108 is installed at the water outlet 203 .

[0043] like Figure 3 As shown, in addition to the water inlet 202 and the water outlet 203, the flow channel 201 also includes a valve installation section 206, a water outlet section 205 and a process port 204. The top end of the valve installation section 206 is open, and the valve installation section 206 is used to accommodate a part of the valve assembly 102. One end of the water outlet section 205 is arranged on the side wall of the valve installation section 206, and the other end of the water outlet section 205 is connected to the water outlet 203. Therefore, the valve installation section 206 is connected to the water outlet 203 (the two are connected through the water outlet section 205). The water outlet section 205 is also connected to the process port 204, and the top end of the process port 204 is located on the top surface of the inner core 107. The process port 204 is provided to facilitate the processing of the flow channel 201 in the inner core 107, and the process port 204 is blocked by a plug 209 (the plug 209 is as shown in FIG. Figure 5 As shown), no water comes out of process port 204.

[0044] The working principle of the valve assembly 102 is introduced below. Figure 5 and Figure 6 In the figure, the dashed line with arrows indicates the flow path of water.

[0045] like Figure 5 As shown, the valve seat 304 of the valve assembly 102 is disposed in the valve mounting section 206, and the valve core 303 is disposed in the valve seat 304. The valve seat 304 includes a valve inlet 309 and a valve outlet 308, the valve inlet 309 is communicated with the water inlet 202, and the valve outlet 308 is communicated with the valve mounting section 206. More specifically, in some embodiments, the valve seat 304 includes an outer tube 310, a connecting sleeve 306 and a bottom cover 307, the bottom cover 307 and the connecting sleeve 306 are both disposed inside the outer tube 310, and the valve inlet 309 and the valve outlet 308 are both disposed in the bottom cover 307. The valve core 303 is also located inside the outer tube 310, and the valve core 303 is located between the connecting sleeve 306 and the bottom cover 307. Please refer to Figure 5 and Figure 6 , the valve core 303 can move back and forth in the valve seat 304.

[0046] like Figure 5 As shown, the valve core 303 of the valve assembly 102 also includes a water outlet 311. When the valve core 303 is in a closed state, the valve core 303 blocks the valve inlet 309; at this time, after water flows from the water inlet 202 to the valve inlet 309, the water cannot completely pass through the valve inlet 309, and the water cannot continue to flow to the water outlet 203, and the water outlet body 101 cannot discharge water. Figure 6 As shown, when the valve core 303 is in the open state, the valve inlet 309, the water outlet 311 and the valve outlet 308 are connected in sequence; accordingly, water can flow through the water inlet 202, the valve inlet 309, the water outlet 311, the valve outlet 308, the valve installation section 206, the water outlet section 205 and the water outlet 203 in sequence, and the water outlet body 101 can discharge water.

[0047] It should be noted that, in other embodiments, when the valve core 303 is in the closed state, the valve core 303 may only block the valve inlet 309, or the valve core 303 may simultaneously block the valve inlet 309 and the valve outlet 308, and such a setting may also prevent water from flowing to the water outlet 203. The movement of the valve core 303 is not limited to forward and backward movement. In other embodiments, the movement of the valve core 303 may also be set to rotation, left and right movement, etc. (the positions of the valve inlet 309, the valve outlet 308 and the water outlet 311 may be adjusted accordingly), as long as the movement of the valve core 303 can switch the valve core 303 between the open state and the closed state.

[0048] In addition, if Figure 6 As shown, there is a gap between the bottom end of the valve outlet 308 and the bottom wall of the valve installation section 206, and there is also a gap between the outer peripheral surface of the outer cylinder 310 and the side wall of the valve installation section 206, and the water outlet section 205 is actually not blocked by the outer cylinder 310. Therefore, the water flowing out of the valve outlet 308 will enter the valve installation section 206, and the water in the valve installation section 206 can flow to the water outlet section 205.

[0049] like Figure 4 As shown, in some embodiments, the valve assembly 102 further includes a handle 301 and a connecting rod 302, and the handle 301 and the top end of the connecting rod 302 are fixed to each other. Figure 5 As shown, the connecting rod 302 is rotatably connected to the connecting sleeve 306 of the valve seat 304, and the bottom end of the connecting rod 302 is rotatably connected to the top end of the valve core 303. Assuming that the valve core 303 is initially in a closed state, if the user lifts the front end of the handle 301 upward, the bottom end of the connecting rod 302 rotates forward to drive the valve core 303 to move forward, thereby switching the valve core 303 from a closed state to an open state. Conversely, assuming that the valve core 303 is initially in an open state, if the user presses the front end of the handle 301 downward, the bottom end of the connecting rod 302 rotates backward to drive the valve core 303 to move backward, thereby switching the valve core 303 from an open state to a closed state.

[0050] like Figure 8 As shown, the valve assembly 102 also includes a first shaft 305 and a second shaft 312, and a mounting groove 313 is provided at the top of the valve core 303. The first shaft 305 and the second shaft 312 pass through the connecting rod 302, and the first shaft 305 is plugged into the connecting sleeve 306 (as shown in FIG. Figure 7 As shown in FIG. 3 , the second shaft 312 is rotatably inserted into the mounting groove 313. In this way, the rotational connection between the connecting rod 302 and the connecting sleeve 306 and the rotational connection between the connecting rod 302 and the valve core 303 can be achieved.

[0051] like Figure 3As shown, the water outlet body 101 further includes a buffer chamber 207, one end of which is provided with an opening 208, and the opening 208 is located on the wall surface of the valve installation section 206. Figure 3 In the illustrated embodiment, the opening 208 is located at the top of the buffer chamber 207, and the opening 208 is located at the bottom wall of the valve mounting section 206. Figure 5 As shown, the basin faucet 100 further includes a piston 401 and an elastic member 403. The piston 401 is movably disposed in the buffer chamber 207, and the piston 401 is sealedly connected to the side wall of the buffer chamber 207. The two ends of the elastic member 403 are respectively connected to the piston 401 and the wall surface of the buffer chamber 207, and the water and / or ice in the flow channel 201 can drive the piston 401 to move so that the piston 401 gradually moves away from the valve installation section 206 (for example, the piston 401 moves downward), and the elastic force of the elastic member 403 is used to drive the piston 401 to move toward the valve installation section 206 to reset the piston 401 (for example, the piston 401 moves upward).

[0052] When the basin faucet 100 is used in a low temperature environment, the water remaining in the flow channel 201 (the valve core 303 is in a closed state) may freeze. Since the volume of water increases after freezing, the pressure of the ice on the valve seat 304 will eventually be transmitted to the internal thread 501 and the external thread 502, which may cause the threaded connection to loosen. In the case where the piston 401 and the buffer chamber 207 are provided, the piston 401 will move downward after the water freezes (such as Figure 7 As shown in FIG. 4 , the buffer chamber 207 can provide space for water and ice, thereby reducing the force of ice on the valve seat 304, thereby reducing the risk of the valve assembly 102 loosening. In addition, even if the water is not frozen, the water pressure may fluctuate during the water discharge process of the basin faucet 100. Under the action of the elastic member 403, the piston 401 can adaptively move according to the change of water pressure, thereby reducing the influence of the water pressure fluctuation on the water discharge effect.

[0053] The following will introduce the connection method between the first joint 104 and the valve seat 304 , and the connection method between the second joint 105 and the water outlet body 101 .

[0054] like Figure 5As shown, in some embodiments, the bottom end surface of the first joint 104 abuts against the valve seat 304, and the first joint 104 and the water outlet body 101 jointly clamp the valve seat 304, so that the valve seat 304 is fixed in the valve installation section 206. More specifically, the bottom end surface of the first joint 104 abuts against a stepped surface of the outer tube 310, and the bottom wall of the valve installation section 206 abuts against the bottom surface of the bottom cover 307. The first joint 104 is equivalent to pressing the valve seat 304 into the valve installation section 206. In addition, since the first joint 104 abuts against the valve seat 304 through its bottom end surface, the first joint 104 does not need to be connected to the valve seat 304 through its surface with the external thread 502, and the matching relationship of each component in the basin faucet 100 is reasonable and does not cause conflict.

[0055] In some embodiments, the outer circumferential surface of the second joint 105 is provided with a groove, and a portion of the water outlet body 101 is embedded in the groove, thereby achieving a fixed connection between the second joint 105 and the water outlet body 101. Since the second joint 105 abuts against the valve seat 304 through its outer circumferential surface, the second joint 105 does not need to be connected to the water outlet body 101 through its surface provided with the internal thread 501, and the matching relationship of the various components in the basin faucet 100 is reasonable and does not cause conflict.

[0056] like Fig. 9 As shown, in some embodiments, the second joint 105 is annular, and the groove may include an annular groove 506, which surrounds the central axis 503 of the joint, and a part of the water outlet body 101 is embedded in the annular groove 506. The groove may also include an axial groove 505, which extends along the axial direction of the joint, and a part of the water outlet body 101 is embedded in the axial groove 505. The shapes of the axial groove 505 and the annular groove 506 are simple and easy to process. In order to improve the connection strength between the water outlet body 101 and the second joint 105, a plurality of axial grooves 505 may be provided. Specifically, the second joint 105 includes a plurality of teeth 504, and an axial groove is formed between every two adjacent teeth 504. In addition, the teeth 504 may be arranged in two rows, and the two rows of teeth 504 are respectively located above and below the annular groove 506. In other embodiments, in order to reduce the difficulty of processing the second joint 105, the groove may also be provided with only an annular groove 506 or only an axial groove 505.

[0057] In some embodiments, a portion of the plastic shell 106 is embedded in the groove, so that the second joint 105 and the water outlet body 101 are fixed to each other. By embedding the plastic shell 106 in the groove, the manufacturing difficulty of the basin faucet 100 can be reduced and the manufacturing efficiency of the basin faucet 100 can be improved. Specifically, in the process of manufacturing the shell 106 by injection molding, the processed second joint 105 can be placed in the mold, and during the injection molding process, the plastic will be embedded in the groove of the second joint 105. This configuration does not require additional protrusions to be processed on the shell 106 of the water outlet body 101 for matching with the groove.
