[0048] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0049] As people's living standards gradually improve and water quality problems become increasingly serious, the water purification function of faucets, as the direct outlet for daily water use, is receiving more and more attention.

[0050] Currently, most faucets do not have the function of filtering or purifying water. Usually, a filter device is installed in the pipe connected to the faucet's liquid path, or an external filter device is hung at the faucet's outlet to filter domestic water. However, external filter devices not only take up a lot of space, but also require disassembly of the filter device and then removal of the filter element for replacement, resulting in low convenience of filter element disassembly and assembly.

[0051] Based on the above-mentioned technical problems, this utility model embodiment is proposed. This utility model embodiment may include a shell 1, a main body 2, and a screw 3. The shell 1 has a receiving cavity 101, and the main body 2 is embedded in the receiving cavity 101. The main body 2 has a first receiving groove and a water outlet channel 201 communicating with the liquid passage of the first receiving groove. A portion of the screw 3 is embedded in the receiving cavity 101 and threadedly connected to the shell 1. The end face of the screw 3 near the main body 2 has a second receiving groove. The screw 3 also has a water inlet channel 301 communicating with the liquid passage of the second receiving groove. The first receiving groove and the second receiving groove cooperate to form a filter cavity 202, which is used to assemble a filter device. Thus, the cooperation of the main body 2 and the screw 3 forms a filter cavity 202 for installing a filter element, which can significantly reduce the space occupied by the externally mounted filter device and greatly improve the convenience of filter element replacement.

[0052] Reference Figures 1-8 This utility model provides a faucet, which may include a housing 1, a body 2, and a screw 3. The housing 1 has a receiving cavity 101, and the body 2 is embedded in the receiving cavity 101. The body 2 has a first receiving groove and a water outlet channel 201 communicating with the liquid passage of the first receiving groove. A portion of the screw 3 is embedded in the receiving cavity 101 and is threadedly connected to the housing 1. The end face of the screw 3 near the body 2 has a second receiving groove, and the screw 3 also has a water inlet channel 301 communicating with the liquid passage of the second receiving groove. The first receiving groove and the second receiving groove cooperate to form a filter cavity 202, which is used to assemble a filter device.

[0053] In this embodiment of the utility model, the faucet may include at least a shell 1, a body 2, and a screw 3. The shell 1 provides structural support for the installation of the body 2. The shell 1 has an accommodating cavity 101 inside. The accommodating cavity 101 has at least one downward opening, so that the body 2 can be assembled into the accommodating cavity 101 from the opening.

[0054] The main body 2 has a first receiving groove and a water outlet channel 201 inside, wherein the first receiving groove and the water outlet channel 201 are in liquid communication. For example, the water outlet channel 201 is opened in a vertical direction, and the opening of the first receiving groove is set downward. The portion of the screw 3 near the main body 2 is embedded in the receiving cavity 101, and the external thread of the screw 3 can engage with the internal thread at the opening of the receiving cavity 101 to form a threaded connection between the screw 3 and the outer shell 1. Thus, when the main body 2 is assembled into the receiving cavity 101, the position of the main body 2 is defined by the threaded connection between the screw 3 and the outer shell 1.

[0055] A second receiving groove is formed on the end face of the screw 3 near the main body 2, with the opening of the second receiving groove facing upwards. This allows the first and second receiving grooves to cooperate to form a filter chamber 202 for housing the filter device. Therefore, when the user needs to use the filter device, they can first assemble the main body 2 into the receiving chamber 101, then install the filter device in the first receiving groove, which limits the position of the filter device. Next, the screw 3 is threadedly connected to the outer shell 1, thus fixing the filter device through the filter chamber 202. The threaded connection between the screw 3 and the outer shell 1 also secures the main body 2. Water flowing into the inlet channel 301 flows to the filter device, is filtered, and then flows out through the outlet channel 201.

[0056] Compared to externally mounting the filter device on the faucet, this embodiment significantly reduces the space occupied by the filter device without requiring additional assembly steps, and improves the ease of assembly and disassembly. For example, when disassembling the filter device is necessary, simply screw the screw 3 to separate it from the housing 1, and then remove the filter device downwards. Specifically, the reduced space occupied by the filter device is mainly reflected in the reduction of the filter housing and filter pipes required for externally mounted filters. This embodiment can partially overlap the water flow path of the faucet itself with the water flow path of the filter device, thereby further reducing the space occupied by the filter device.

[0057] When the user does not need to use the filter device, the main body 2 can be first assembled into the receiving cavity 101, and then the screw 3 can be threadedly connected to the outer shell 1. The main body 2 is fixed through the threaded connection between the screw 3 and the outer shell 1. Thus, the water flowing into the inlet channel 301 flows into the filter cavity 202, and then flows through the filter cavity 202 to the outlet channel 201. This embodiment of the invention increases the applicability of the faucet. For example, when the user does not want to use the filter device, it can be left unassembled in the filter cavity 202. When the user wants to use the filter device, it can be placed in the filter cavity 202. This enriches the faucet's functions, makes it easier for users to choose, and improves the user experience.

[0058] An optional utility model embodiment, referring to... Figure 1 and Figure 3 As shown, the faucet also includes an external pressure filter device 4, which is embedded in the filter chamber 202. Water in the inlet channel 301 flows into the filter chamber 202, then flows from the filter chamber 202 into the interior of the external pressure filter device 4, and then flows through the interior of the external pressure filter device 4 into the outlet channel 201.

[0059] In this embodiment of the present invention, the faucet may further include an external pressure filter device 4. The external pressure filter device 4 can be understood as a filter device in which the water to be filtered flows from the outside of the filter element to the inside of the filter element, and the filtered water flows out from the inside of the filter element. The external pressure filter device 4 is embedded in the filter chamber 202. For example, it can be fixedly connected to the bottom of the first receiving groove of the main body 2, thus limiting the external pressure filter device 4 in the vertical direction. A certain gap exists between the bottom of the external pressure filter device 4 and the screw 3 to ensure that water can enter the filter chamber 202 from the inlet channel 301. The water then flows through the filter chamber 202 to the inside of the external pressure filter device 4, and then through the inside of the external pressure filter device 4 to the outlet channel 201. Therefore, when the faucet is turned on, the water flowing out of the outlet channel 201 is filtered water.

[0060] An optional utility model embodiment, referring to... Figure 3 and Figure 4As shown, the external pressure filtration device 4 may include a first filter element 41, a first upper cover 42, and a first lower cover 43. The first upper cover 42 is located above the first filter element 41, communicating with the interior of the first filter element 41 and with the liquid path of the water outlet channel 201. The first lower cover 43 is located below the first filter element 41 and forms a seal on the bottom of the first filter element 41. Water in the filtration chamber 202 flows into the interior of the external pressure filtration device 4 through the gap between the first upper cover 42 and the first lower cover 43.

[0061] In this embodiment of the invention, the external pressure filter device 4 can be understood as a filter device in which the water to be filtered flows from the outside of the filter element to the inside of the filter element, and the filtered water flows out from the inside of the filter element. The external pressure filter device 4 is embedded in the filter chamber 202. For example, the external pressure filter device 4 can be fixedly connected to the bottom of the first receiving groove of the main body 2 to form a vertical limit on the external pressure filter device 4. A certain gap exists between the bottom of the external pressure filter device 4 and the screw 3 to ensure that the water flow can enter the filter chamber 202 from the water inlet channel 301. Then, the water flows through the filter chamber 202 to the inside of the external pressure filter device 4, and then through the inside of the external pressure filter device 4 to the water outlet channel 201. At this time, when the faucet is turned on, the water flowing out of the water outlet channel 201 is filtered water.

[0062] In some specific embodiments, the external pressure filtration device 4 may include a first filter element 41, a first upper end cap 42, and a first lower end cap 43. For example, the first filter element 41 may be a cylindrical structure with a water passage in the middle. The first upper end cap 42 is located above the first filter element 41 and covers the upper end surface of the first filter element 41, wherein the first upper end cap 42 has a water inlet channel communicating with the water passage. The first lower end cap 43 is located below the first filter element 41 and covers the lower end surface of the first filter element 41, thus sealing the lower end surface of the first filter element 41. The first upper end cap 42 and the first lower end cap 43 cooperate to provide structural support for the first filter element 41 and define the filtration path of the first filter element 41. For example, the second filter element 51 and the second upper end cap 52 may be an interference fit, and the second filter element 51 and the second lower end cap 53 may also be an interference fit.

[0063] Water flows into the filter chamber 202 through the inlet channel 301, passes through the area between the first upper end cover 42 and the first lower end cover 43, flows through the first filter element 41 and enters the water passage of the first filter element 41, completing the filtration of the water. The filtered water flows through the water passage to the water inlet channel of the first upper end cover 42, and then through the water inlet channel to the outlet channel 201, which is connected to the water inlet channel.

[0064] In some embodiments, a limiting protrusion may be provided on the end face of the first upper end cover 42 facing the first filter element 41. The water channel may be opened in the limiting protrusion. The limiting protrusion may extend into the water passage of the first filter element 41 and form a clearance fit with the water passage. Thus, when assembling the first upper end cover 42 and the first filter element 41, the first filter element 41 can be assembled and positioned by the limiting protrusion.

[0065] In other embodiments, an assembly protrusion may be provided on the end face of the first upper cover 42 away from the first filter element 41, and the water channel may pass through the assembly protrusion. The assembly protrusion is used to mate with the shape of the wall of the first receiving groove, so that during the assembly of the external pressure filter device 4, the external pressure filter device 4 can be positioned by the shape of the assembly protrusion mating with the first receiving groove. In other words, the external pressure filter device 4 can be quickly inserted into the main body 2. The limiting protrusion, the assembly protrusion, and the first upper cover 42 can be an integral structure.

[0066] An optional utility model embodiment, referring to... Figure 3 and Figure 4 As shown, the external pressure filter device 4 also includes a first sealing ring 44, which is sleeved on the first upper end cover 42 to form a pressure seal between the main body 2 and the first upper end cover 42.

[0067] In this embodiment of the present invention, the external pressure filter device 4 further includes a first sealing ring 44. Correspondingly, an annular first sealing groove is formed on the mounting protrusion of the first upper end cover 42. The first sealing ring 44 is sleeved on the mounting protrusion of the first upper end cover 42 and embedded in the first sealing groove. When the first upper end cover 42 is assembled onto the main body 2, the first sealing ring 44 is deformed under pressure and forms pressure contact with the groove wall of the first receiving groove. Thus, the relative position of the first upper end cover 42 and the main body 2 can be locked by the pressure contact force. Furthermore, the setting of the first sealing ring 44 can also prevent water flowing into the water outlet channel 201 from flowing back into the filter chamber 202 through the gap between the first upper end cover 42 and the main body 2, ensuring the water passage sealing at the connection between the first upper end cover 42 and the main body 2. In addition, the external pressure filter device 4 is fixed by the deformation force of the first sealing ring 44, which can improve the ease of disassembly and assembly of the external pressure filter device 4. For example, when it is necessary to disassemble the external pressure filter device 4, the screw 3 is pre-tightened to separate it from the main body 2, and then the external pressure filter device 4 can be taken out from the first receiving groove of the main body 2. It does not require any disassembly or assembly tools, and the disassembly and assembly process is simple.

[0068] Those skilled in the art can determine the number of the first sealing rings 44 based on the actual length of the assembly protrusion. For example, the first sealing rings 44 can be set to 1, 2, or 3, without further limitation.

[0069] An optional utility model embodiment, referring to... Figure 6 and Figure 7 As shown, the faucet also includes an internal pressure filter device 5, which is embedded in the filter chamber 202. Water in the inlet channel 301 flows into the internal pressure filter device 5, then flows through the internal pressure filter device 5 into the filter chamber 202, and then flows from the filter chamber 202 into the outlet channel 201.

[0070] In this embodiment of the present invention, the faucet may further include an internal pressure filter device 5. The internal pressure filter device 5 can be understood as a filter device in which the water to be filtered flows from the inside of the filter element to the outside of the filter element, and the filtered water flows out from the outside of the filter element. The internal pressure filter device 5 is embedded in the filter chamber 202. For example, it can be fixedly connected to the bottom of the first receiving groove of the screw 3, thus limiting the internal pressure filter device 5 in the vertical direction. A certain gap exists between the top of the internal pressure filter device 5 and the main body 2 to ensure that the water can flow from the filter chamber 202 out of the outlet channel 201. Therefore, the water in the inlet channel 301 first flows into the interior of the internal pressure filter device 5 for filtration, and the filtered water flows from the interior of the internal pressure filter into the filter chamber 202, and then from the filter chamber 202 into the outlet channel 201. At this time, when the faucet is turned on, the water flowing out of the water outlet channel 201 is filtered water.

[0071] An optional utility model embodiment, referring to... Figure 7 and Figure 8 As shown, the internal pressure filtration device 5 may include a second filter element 51, a second upper end cover 52, and a second lower end cover 53. The second upper end cover 52 is located above the second filter element 51 and has a water passage hole 5201. The second lower end cover 53 is located below the second filter element 51 and is fixedly connected to the second upper end cover 52. The second lower end cover 53 communicates with the interior of the second filter element 51 and with the liquid path of the water inlet channel 301. Water in the water inlet channel 301 flows into the interior of the second filter element 51 and then flows into the filter chamber 202 through the water passage hole 5201.

[0072] In this embodiment of the invention, the internal pressure filter device 5 can be understood as a filter device in which the water to be filtered flows from the inside of the filter element to the outside of the filter element, and the filtered water flows out from the outside of the filter element. The internal pressure filter device 5 is embedded in the filter cavity 202. For example, it can be fixedly connected to the bottom of the first receiving groove of the screw 3 to form a vertical limit on the internal pressure filter device 5. And by having a certain gap between the top of the internal pressure filter device 5 and the main body 2, it is ensured that the water can flow from the filter cavity 202 to the outlet channel 201. Thus, the water in the inlet channel 301 first flows into the inside of the internal pressure filter device 5 for filtration, and the filtered water flows from the inside of the internal pressure filter to the filter cavity 202, and then from the filter cavity 202 to the outlet channel 201. At this time, when the faucet is turned on, the water flowing out of the outlet channel 201 is the filtered water.

[0073] In some optional embodiments of the utility model, the internal pressure filtration device 5 may further include a second filter element 51, a second upper end cover 52, and a second lower end cover 53. For example, the second filter element 51 may have at least one water passage. The second upper end cover 52 is located above the second filter element 51 and covers the upper end surface of the second filter element 51. The second upper end cover 52 has a water passage hole 5201, which communicates with the liquid path of the filtration chamber 202, so that water in the water passage of the second filter element 51 can enter the filtration chamber 202 through the water passage hole 5201.

[0074] The second lower end cap 53 is located below the second filter element 51 and covers the lower end surface of the second filter element 51. The second upper end cap 52 and the second lower end cap 53 can form surface contact, ensuring that water in the second filter element 51 can only flow from the water passage 5201 into the filter chamber 202. The second filter element 51 and the second upper end cap 52 can be interference-fitted, and the second filter element 51 and the second lower end cap 53 can also be interference-fitted. The second lower end cap 53 is provided with a water inlet protrusion that extends downwards along the end surface of the second lower end cap 53 away from the second filter element 51. The water inlet protrusion mates with the shape of the second receiving groove of the screw 3 to assemble and position the internal pressure filter device 5. In other words, the internal pressure filter device 5 can be quickly inserted into the main body 2. The inlet protrusion has a channel connecting the water passage and the inlet channel 301. Water flows from the inlet channel 301 into the water passage of the second filter element 51, then through the water passage hole 5201 of the second upper end cover 52, and into the filter chamber 202. The water flowing into the filter chamber 202 is filtered water, and the filtered water flows into the outlet channel 201. The inlet protrusion and the second lower end cover 53 can be an integral structure.

[0075] In this embodiment of the invention, the first filter element 41 and the second filter element 51 may each include at least one of the following types: polypropylene cotton (PP) filter element, polyamide composite activated carbon (PAC) filter element, carbon rod filter element, carbon fiber filter element, ultrafiltration membrane filter element, resin filter element, and filter media filter element, etc. For example, if the first filter element 41 includes two types, the first filter element 41 can be obtained by stacking the two types of filter elements, so that the water to be filtered can pass through the first filter element 41 in sequence.

[0076] An optional utility model embodiment, referring to... Figure 7 and Figure 8 As shown, the internal pressure filter device 5 also includes a second sealing ring 54, which is sleeved on the second lower end cover 53 to form a pressure seal between the screw 3 and the second lower end cover 53.

[0077] In this embodiment of the present invention, the internal pressure filter device 5 further includes a second sealing ring 54. Correspondingly, an annular second sealing groove is formed on the water inlet protrusion of the second lower end cover 53. The second sealing ring 54 is sleeved on the water inlet protrusion of the second lower end cover 53 and embedded in the second sealing groove. When the second lower end cover 53 is assembled onto the screw 3, the second sealing ring 54 is deformed under pressure and forms pressure contact with the groove wall of the second receiving groove. Thus, the relative position of the second lower end cover 53 and the screw 3 can be locked by the pressure contact force. Furthermore, the setting of the second sealing ring 54 can also prevent water from entering the water inlet channel 301 and flow directly into the filter chamber 202 through the gap between the second lower end cover 53 and the screw 3, ensuring the water passage sealing at the connection between the second lower end cover 53 and the screw 3. In addition, the internal pressure filter device 5 is fixed by the deformation force of the second sealing ring 54, which can improve the ease of disassembly and assembly of the internal pressure filter device 5. For example, when it is necessary to disassemble the internal pressure filter device 5, the screw 3 is pre-tightened to separate it from the main body 2, and then the internal pressure filter device 5 can be taken out from the second receiving groove of the screw 3. It does not require any disassembly or assembly tools, and the disassembly and assembly process is simple.

[0078] Those skilled in the art can determine the number of the second sealing rings 54 based on the actual length of the water inlet protrusion. For example, the second sealing rings 54 can be set to 1, 2, or 3, without further limitation.

[0079] Compared to externally mounting the filter device on the faucet, this embodiment significantly reduces the space occupied by the filter device without requiring additional assembly steps, and improves the ease of assembly and disassembly. For example, when disassembling the filter device is necessary, simply screw the screw 3 to separate it from the housing 1, and then remove the filter device downwards. Specifically, the reduced space occupied by the filter device is mainly reflected in the reduction of the filter housing and filter pipes required for externally mounted filters. This embodiment can partially overlap the water flow path of the faucet itself with the water flow path of the filter device, thereby further reducing the space occupied by the filter device.

[0080] When the user does not need to use the filter device, the main body 2 can be first assembled into the receiving cavity 101, and then the screw 3 can be threadedly connected to the outer shell 1. The main body 2 is fixed through the threaded connection between the screw 3 and the outer shell 1. Thus, the water flowing into the inlet channel 301 flows into the filter cavity 202, and then flows through the filter cavity 202 to the outlet channel 201. This embodiment of the invention increases the applicability of the faucet. For example, when the user does not want to use the filter device, it can be left unassembled in the filter cavity 202. When the user wants to use the filter device, it can be placed in the filter cavity 202. This enriches the faucet's functions, makes it easier for users to choose, and improves the user experience.

[0081] An optional utility model embodiment, referring to... Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 as well as Figure 7 As shown, the faucet may further include a base 6 and a nut 7.

[0082] In this embodiment of the invention, the faucet may further include a base 6 and a nut 7, wherein the base 6 and the nut 7 are respectively sleeved on the screw 3, wherein the top end of the base 6 contacts the bottom of the outer casing 1, and the bottom end of the base 6 is used to contact the mounting surface, for example, the mounting surface may include but is not limited to the countertop of a sink. Thus, the base 6 increases the contact area between the faucet and the mounting surface, improving the installation stability of the faucet. The nut 7 and the base 6 are spaced apart along the axial direction of the screw 3, and the internal thread of the nut 7 engages with the external thread of the screw 3. During the assembly of the faucet, the base 6 can form a surface contact with the upper end surface of the mounting surface, and then the nut 7 is screwed from the lower end surface of the mounting surface, causing the nut 7 to move closer to the base 6. Finally, the nut 7 and the base 6 clamp the mounting surface, and the nut 7 is locked in position through the threaded connection between the nut 7 and the screw 3, completing the fixation of the faucet on the mounting surface.

[0083] An optional utility model embodiment, referring to... Figure 3 and Figure 7As shown, the faucet also includes a first washer 8 and a second washer 9. The first washer 8 is located below the base 6, and the second washer 9 is located above the nut 7.
