[0019] Compared with the prior art, the technical solution of this utility model embodiment has the following beneficial effects:

[0020] The faucet provided by this utility model effectively purifies and filters impurities, residual chlorine, heavy metals, and other substances in the water by adding the filter element assembly inside the main body tube, thereby improving water quality. The filter element assembly and the water outlet pipe are detachably connected, and the main body tube and the water outlet pipe are also detachably connected. Therefore, the filter element assembly can be removed and replaced easily by disassembling the main body tube and the water outlet pipe. Furthermore, the water outlet head and the water outlet pipe are rotatably connected, and the water outlet head rotates around the second direction. Therefore, the water outlet head can be rotated to allow water to flow upwards, facilitating users' needs for rinsing their mouths and washing their faces.

[0021] Furthermore, it also includes an aerator, which is fixedly connected to the outlet of the water outlet head. The aerator creates a foaming effect by fully mixing the water flow with air, thereby increasing the flushing force of the water and reducing water consumption. In addition, the water flow after mixing with air becomes gentler, reducing the impact force of the water, thus preventing water splashing and reducing noise.

[0022] Furthermore, the water outlet pipe is rotatably connected to the main pipe, and the water outlet pipe rotates around the first direction. By rotating the water outlet pipe, the water demand of different areas can be met.

[0023] Furthermore, it also includes: a first functional tube, which is fixedly connected to the main body tube; a thermostatic valve, the thermostatic valve core of which is disposed within the first functional tube, and the thermostatic valve is used to regulate the water temperature; a second functional tube, which is fixedly connected to the main body tube, and the first functional tube and the second functional tube are respectively disposed on different sides of the main body tube; and a push-button valve, the push-button valve core of which is disposed within the second functional tube, and the push-button valve is used to regulate the water flow rate. By disposing the thermostatic valve and the push-button valve on different sides of the main body tube, it is convenient for the user to operate with both hands simultaneously, thereby improving the efficiency of water flow regulation.

[0024] Furthermore, the thermostatic valve also includes a thermostatic locking key, which is correspondingly configured with the thermostatic control sleeve and fixedly connected to it. The thermostatic locking key is used to lock the thermostatic control sleeve. After the thermostatic control sleeve has adjusted the water temperature, pressing the thermostatic locking key locks the sleeve. When the user needs to adjust the temperature again, pressing the thermostatic locking key unlocks the sleeve. The added thermostatic locking key prevents accidental changes to the water temperature due to accidental contact with the thermostatic control sleeve after the user has adjusted the water temperature.

[0032] As described in the background section, existing faucets still have many problems. These will be explained in detail below.

[0033] Existing faucets have limited functionality and cannot meet many daily needs. For example, many faucets lack filters, failing to remove impurities, residual chlorine, heavy metals, and other substances from the water. Furthermore, the water flow from current faucets is always downward, making it extremely inconvenient for everyday activities such as rinsing the mouth and washing the face.

[0034] Based on this, the present invention provides a faucet that, by adding the filter element assembly inside the main body tube, can effectively purify and filter impurities, residual chlorine, heavy metals, and other substances in the water, thereby improving water quality. The filter element assembly and the water outlet pipe are detachably connected, and the main body tube and the water outlet pipe are also detachably connected. Therefore, by disassembling the main body tube and the water outlet pipe, the filter element assembly can be removed and replaced, making operation convenient. Furthermore, the water outlet head and the water outlet pipe are rotatably connected, and the water outlet head rotates around the second direction. Therefore, the water outlet head can be rotated to allow water to flow upwards, facilitating users' needs for rinsing their mouths and washing their faces.

[0037] Figure 1 is an exploded view of the faucet according to an embodiment of the present invention; Figure 2 is an overall appearance view of the assembled faucet according to an embodiment of the present invention; Figure 3 is a cross-sectional view along line AA in Figure 2; Figure 4 is a cross-sectional view along line BB in Figure 2; Figure 5 is a structural schematic diagram of the locking ring in the faucet according to an embodiment of the present invention; Figure 6 is a structural schematic diagram of the locking inner ring of the locking ring in the faucet according to an embodiment of the present invention; Figure 7 is a structural schematic diagram of the locking button of the locking ring in the faucet according to an embodiment of the present invention.

[0038] Please refer to Figures 1 and 2. A faucet includes: a main body pipe 100 extending along a first direction X; a water outlet pipe 200 extending along a second direction Y, wherein the first direction X is different from the second direction Y, and the main body pipe 100 and the water outlet pipe 200 are detachably connected; a filter element assembly 300 detachably connected to the water outlet pipe 200 and assembled inside the cavity of the main body pipe 100; and a water outlet head 400 rotatably connected to the water outlet pipe 200 and rotating around the second direction Y.

[0039] By adding the filter element assembly 300 inside the main tube 100, impurities, residual chlorine, heavy metals, and other substances in the water can be effectively purified and filtered, thereby improving water quality. The filter element assembly 300 and the water outlet pipe 200 are detachably connected, and the main tube 100 and the water outlet pipe 200 are also detachably connected. Therefore, by disassembling the main tube 100 and the water outlet pipe 200, the filter element assembly 300 can be removed and replaced, making the operation convenient. Furthermore, the water outlet head 400 is rotatably connected to the water outlet pipe 200, and the water outlet head 400 rotates around the second direction Y. Therefore, the water outlet head 400 can be rotated to allow water to flow upwards, facilitating users' needs for rinsing their mouths and washing their faces.

[0040] In this embodiment, the first direction X is perpendicular to the second direction Y.

[0041] In other embodiments, the first direction X and the second direction Y may also be other obtuse angles that are not perpendicular.

[0042] Please continue referring to Figure 1 and, in conjunction with Figures 3 to 6, in this embodiment, the filter element assembly 300 includes: a filter element base 3001, which is fitted inside the receiving portion 2001 of the water outlet pipe 200, and the receiving portion 2001 extends along the first direction X; a filter element 3002, which is fitted inside the filter element base 3001, and the filter element 3002 extends along the first direction X; a filter element connecting sleeve 3003, which is fitted outside the receiving portion 2001; and a locking ring 3004, which includes a locking inner ring 3004a and a locking outer ring 3004b concentrically arranged, the locking outer ring 3004b being fixedly connected to the main body pipe 100, and the locking inner ring 3004a being fitted outside the filter element connecting sleeve 3003.

[0043] Please refer to Figure 7. In this embodiment, the locking inner ring 3004a is an elastic element; the locking ring 3004 further includes a locking button 3004c, which is connected to the locking inner ring 3004a. When the locking button 3004c is pressed, the locking inner ring 3004a expands circumferentially.

[0044] It should be noted that the locking button 3004c is located on the outside of the main body tube 100 for easy pressing and disassembly by the user. When the locking ring 3004 is in the locked state, the diameter of the locking inner ring 3004b is small, and the filter element connecting sleeve 3003, the filter element base 3001, and the filter element 3002 cannot pass through the diameter of the locking inner ring 3004a, thus being locked within the cavity of the main body tube 100. When the locking inner ring 3004a is pressed, the diameter of the locking inner ring 3004a expands circumferentially, allowing the filter element connecting sleeve 3003, the filter element base 3001, and the filter element 3002 to be pulled out from the diameter of the locking inner ring 3004a, thereby enabling the replacement of the filter element 3002.

[0045] Please continue to refer to Figure 1. In this embodiment, the outer wall of the filter element connecting sleeve 3003 is provided with a limiting groove 3003a, and the locking inner ring 3004a is fitted into the limiting groove 3003a.

[0046] In this embodiment, the filter material in the filter element 3002 includes: PP cotton, activated carbon, ceramics, or other microfiltration and ultrafiltration materials.

[0047] Please continue to refer to Figure 4. In this embodiment, the faucet further includes: a water outlet connecting sleeve 2002, which is fixed inside the water outlet pipe 200; and a water outlet connector 2003, one end of which is fitted inside the water outlet connecting sleeve 2002, and the other end of which is fixedly connected to the water outlet head 400.

[0048] The water outlet head 400 and the water outlet pipe 200 are connected via the water outlet connector 2003. One end of the water outlet connector 2003 is threaded to the water outlet head 400, and the other end is connected to the water outlet pipe 200 via a set screw (not shown). The water outlet connector 2003 has sealing rings (not shown) at the cross-sections between the water outlet pipe 200 and the water outlet head 400 to achieve a sealing function. The water outlet connecting sleeve 2002 is fixedly connected to the water outlet pipe 200 via a locking screw (not shown).

[0049] Please continue referring to Figures 1 and 4. In this embodiment, the faucet further includes an aerator 500, which is fixedly connected to the outlet of the water outlet 400. The aerator 500 creates a foaming effect by fully mixing the water flow with air, thereby increasing the water's flushing force and reducing water consumption. Furthermore, the water flow after mixing with air becomes gentler, reducing the water's impact force, thus preventing splashing and reducing noise.

[0050] In this embodiment, the aerator 500 and the water outlet 400 are fixedly connected by threads.

[0051] Please continue referring to Figure 1. In this embodiment, the water outlet pipe 200 is rotatably connected to the main body pipe 100, and the water outlet pipe 200 rotates around the first direction X. The rotation of the water outlet pipe 200 can meet the water needs of different areas.

[0052] It should be noted that the rotatable connection between the water outlet pipe 200 and the main body pipe 100 relies on the locking inner ring 3004a and the filter element connecting sleeve 3003 as intermediate rotating components. Since the receiving part 2001 of the water outlet pipe 200 is fitted into the filter element connecting sleeve 3003 when the locking ring is in the locked state, and the filter element connecting sleeve 3003 is fitted into the locking inner ring 3004a, the rotatable connection between the water outlet pipe 200 and the main body pipe 100 can be achieved based on the locking inner ring 3004a and the filter element connecting sleeve 3003.

[0053] Please continue referring to Figures 1 and 3. In this embodiment, the faucet further includes: a first functional tube 101, which is fixedly connected to the main body tube 100; a thermostatic valve 600, the core of which is disposed within the first functional tube 101, and used to regulate water temperature; a second functional tube 102, which is fixedly connected to the main body tube 100, and the first functional tube 101 and the second functional tube 102 are respectively disposed on different sides of the main body tube 100; and a push-button valve 700, the core of which is disposed within the second functional tube 102, and used to regulate water flow speed. By disposing the thermostatic valve 600 and the push-button valve 700 on different sides of the main body tube 100, it is convenient for the user to operate with both hands simultaneously, thereby improving the efficiency of water flow regulation.

[0054] In this embodiment, specifically, the first functional tube 101 and the second functional tube 102 are respectively disposed on opposite sides of the main tube 100.

[0055] Please continue to refer to Figures 1 and 3. In this embodiment, the thermostatic valve 600 includes: a thermostatic connector 6001, which is fixedly connected to the inner wall of the first functional tube 101; a thermostatic valve core assembly 6002, which is fitted inside the thermostatic connector 6001; a thermostatic control sleeve 6003, which is fitted outside the thermostatic valve core assembly 6002; and a thermostatic end cap 6004, which is fitted outside the thermostatic control sleeve 6003.

[0056] In this embodiment, cold tap water and hot tap water after heating enter through independent water paths. After being mixed by the thermostatic valve core assembly 6002, the water temperature reaches a suitable temperature for use. The thermostatic valve core assembly 6002 has a default set output temperature (e.g., 38°C). If it is necessary to adjust the default temperature of warm water, rotate the thermostatic end cap 6004, which in turn drives the thermostatic control sleeve 6003 to rotate, thereby adjusting the output temperature of warm water.

[0057] Please continue to refer to Figures 1 and 3. In this embodiment, the thermostatic valve 600 further includes a thermostatic locking key 6005, which is correspondingly provided with the thermostatic control sleeve 6003. The thermostatic locking key 6005 is fixedly connected to the thermostatic sleeve and is used to lock the thermostatic control sleeve 6003.

[0058] After the thermostat control sleeve 6003 has adjusted the water temperature, the thermostat control sleeve 6003 can be locked by pressing the thermostat lock button 6005. When the user needs to adjust the temperature again, the thermostat control sleeve 6003 can be unlocked by pressing the thermostat lock button 6005 again. The added thermostat lock button 6005 can prevent accidental operation that would change the water temperature after the user has adjusted the water temperature by touching the thermostat control sleeve 6003 again.

[0059] Please continue to refer to Figures 1 and 3. In this embodiment, the press valve 700 includes: a press flow valve core assembly 7001, which is fixedly connected to the inside of the second functional tube 102; and a press end cap 7002, which is fitted onto the outside of the press flow valve core assembly 7001.

[0060] In this embodiment, the water flow after temperature adjustment flows through the press flow valve core assembly 7001. The press flow valve core assembly 7001 has the function of being able to rotate and adjust the water flow to achieve a suitable water flow speed. It also has a switching function. By axially pressing the press end cover 7002, the press flow valve core assembly 7001 can be driven to realize the switching of water flow.

[0061] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
