Description

Technical Field

[0001] This utility model relates to the technical field of water purifier faucets, and more specifically to a water purifier faucet with a three-speed switching function. Background Technology

[0002] In recent years, with the popularization of water purification technology and the expansion of users' water usage methods, faucets with integrated water purification functions have gradually become a market hotspot. These faucets are typically equipped with a water purifier, thus providing purified water output. Beyond this, they can also be expanded to include showerhead and foam spray functions. To achieve multi-level adjustment, existing technologies mostly employ a rotary valve structure. This structure mainly includes a baffle plate for separating flow channels and a sealing ring. The baffle plate has multiple water distribution holes, which connect to different flow channels. By moving the sealing ring, the opening and closing of different water distribution holes is controlled, thus enabling the switching of different flow channels and achieving multi-level adjustment. However, in existing designs, to control the opening and closing of different water distribution holes, the sealing ring needs to slide relative to the baffle plate. With increased use, the sealing ring gradually wears down, leading to a decrease in the sealing reliability of the water distribution holes and subsequent leakage. This seriously affects user experience and product lifespan. Utility Model Content

[0003] The purpose of this invention is to solve the problem in the prior art that as the usage time increases, the sealing ring will gradually wear down, resulting in a decrease in the sealing reliability of the sealing ring to the water distribution hole, and thus water leakage, which seriously affects the user experience and product life.

[0004] To solve the above problems, this utility model provides a water purifier faucet with a three-speed switching function, including a shell and a switching core. The upper part of the shell is provided with a water inlet channel and the lower part is provided with a first water outlet channel, a second water outlet channel and a third water outlet channel respectively. The middle part of the shell is provided with a partition. The partition is provided with a first through hole, a second through hole and a third through hole arranged at intervals. The first through hole connects the water inlet channel and the first water outlet channel, the second through hole connects the water inlet channel and the second water outlet channel, and the third through hole connects the water inlet channel and the third water outlet channel.

[0005] The switching core is disposed inside the outer casing and includes an adjustment frame, a rotating shaft, and an operating component. The adjustment frame is provided with a first pressure head, a first elastic element acting on the first pressure head and pushing the first pressure head to abut against a partition, a second pressure head, and a second elastic element acting on the second pressure head and pushing the second pressure head to abut against a partition. The first pressure head and the second pressure head are spaced apart and the gap is larger than the diameter of the second through hole. The rotating shaft is rotatably connected inside the outer casing and connected to the adjustment frame. The operating component includes a receiving end connected to the rotating shaft and a hand-operated end extending outside the outer casing.

[0006] The operating component drives the adjustment frame to move via a rotating shaft, so that the first pressure head and the second pressure head can respectively close any two of the first through hole, the second through hole and the third through hole.

[0007] Compared with the existing technology, the above solution optimizes the structure of the switching core by designing the adjustment frame to include a first pressure head, a first elastic element, a second pressure head, and a second elastic element. The first and second pressure heads are used to close any two of the first, second, and third through holes. The first and second elastic elements apply elastic thrust to the first and second pressure heads respectively, ensuring that the first and second pressure heads are always in contact with the partition. This ensures that even if the first and second pressure heads wear, they can still achieve a good sealing effect on the first, second, and third through holes, effectively improving their service life.

[0008] In an improved embodiment, the first pressure head is a first cap parallel to the partition, and the length of the first cap is greater than the distance between the first through hole and the second through hole, thereby achieving simultaneous closure of the first through hole and the second through hole; the second pressure head is a second cap parallel to the partition, and the length of the second cap is greater than the distance between the second through hole and the third through hole, thereby achieving simultaneous closure of the second through hole and the third through hole; the gap between the first cap and the second cap is greater than the diameter of the second through hole; the cap-like structure of the first cap and the second cap can achieve a good sealing effect on the first through hole, the second through hole and the third through hole, and the structure is reliable.

[0009] In an improved embodiment, the adjusting frame is provided with a first guide sleeve and a second guide sleeve, both perpendicular to the partition. The first cover is slidably connected to the lower part of the first guide sleeve. The first elastic element is a spring, with its upper end connected to the upper part of the first guide sleeve and its lower part acting on the first cover. The second cover is slidably connected to the lower part of the second guide sleeve. The second elastic element is a spring, with its upper end connected to the upper part of the second guide sleeve and its lower part acting on the second cover. Thus, the first guide sleeve guides the first cover and the first spring, and the second guide sleeve guides the second cover and the second spring, making the overall structure more reliable.

[0010] In an improved embodiment, the first pressure head consists of two first plugs, and the first elastic element consists of two first springs. The two first springs act on the two first plugs respectively, causing the two first plugs to abut against the partition. The distance between the two first plugs corresponds to the distance between the first through hole and the second through hole, thereby achieving simultaneous sealing of the first and second through holes. The second pressure head consists of two second plugs, and the second elastic element consists of two second springs. The two second springs act on the two second plugs respectively, causing the two second plugs to abut against the partition. The distance between the two second plugs corresponds to the distance between the second and third through holes, thereby achieving simultaneous sealing of the second and third through holes. Since both the first and second plugs are spherical, they experience rolling friction with the partition, thereby ensuring the sealing effect of the first, second, and third through holes while further reducing wear.

[0011] In an improved embodiment, the adjusting frame is provided with two first guide sleeves and two second guide sleeves, each perpendicular to the partition. Two first plugs are slidably connected to the lower parts of the two first guide sleeves. The upper ends of two first springs are connected to the upper parts of the two first guide sleeves, and their lower ends act on the two first plugs. Two second plugs are slidably connected to the lower parts of the two second guide sleeves. The upper ends of two second springs are connected to the upper parts of the two second guide sleeves, and their lower ends act on the two second plugs. Thus, the first guide sleeves guide the first plugs and the first springs, and the second guide sleeves guide the second plugs and the second springs, making the overall structure more reliable.

[0012] In an improved embodiment, the upper side of the housing is provided with a water inlet that connects to the water inlet channel, the lower side of the housing is provided with a bubble outlet that connects to the first water outlet channel and a shower head that connects to the third water outlet channel, and the side of the housing is provided with a water purifier that connects to the second water outlet channel.

[0013] In an improved embodiment, the water purifier includes a housing and a filter element. The housing has an inner cavity and an inlet and an outlet that are connected to the inner cavity. The inlet is connected to a second water outlet channel. The outlet is vertically located on the lower side of the housing. A base is provided inside the housing. The filter element is detachably connected to the base and separates the inlet and outlet, so that water flowing into the inner cavity from the inlet is filtered by the filter element and then discharged from the outlet.

[0014] In an improved embodiment, the base has a mounting groove in the middle, the filter element includes a mounting end that is inserted into the mounting groove, the mounting groove has a limiting rib parallel to the insertion direction of the filter element, and the mounting end of the filter element has a limiting groove for the limiting rib to be inserted into. Thus, the mounting end of the filter element is positioned by the cooperation of the limiting rib and the limiting groove, avoiding misalignment of the mounting end of the filter element during assembly.

[0015] In an improved embodiment, the side wall of the housing located below the partition is provided with a receiving pipe. The receiving pipe includes a first end that connects to the water inlet and a second end that connects to the second water outlet. A sealing ring is installed between the first end of the receiving pipe and the housing, thereby effectively improving the connection sealing between the water inlet and the receiving pipe through the sealing ring. The structure is simple and reliable.

[0016] In an improved embodiment, the operating component is rod-shaped, and the side wall of the housing has a transversely formed elongated groove for the hand-operated end of the operating component to extend out. When the operating component abuts against one end of the elongated groove, the first and second through holes are closed. When the operating component abuts against the other end of the elongated groove, the second and third through holes are closed. When the operating component is located in the middle of the elongated groove, the first and third through holes are closed, making operation simple and convenient. Attached Figure Description

[0032] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] Please see Figures 1-7The present invention provides a water purifier faucet with a three-speed switching function, comprising an outer shell 1 and a switching inner core. The upper part of the outer shell 1 is provided with a water inlet channel 11 and the lower part is provided with a first water outlet channel 12, a second water outlet channel 13 and a third water outlet channel 14 respectively. The middle part of the outer shell 1 is provided with a partition 2. The partition 2 is provided with a first through hole 21, a second through hole 22 and a third through hole 23 arranged at intervals. The first through hole 21 connects the water inlet channel 11 and the first water outlet channel 12, the second through hole 22 connects the water inlet channel 11 and the second water outlet channel 13, and the third through hole 23 connects the water inlet channel 11 and the third water outlet channel 14.

[0034] The switching core is set inside the outer shell 1 and includes an adjustment frame 3, a rotating shaft 4 and an operating component 5. The adjustment frame 3 is provided with a first pressure head 31, a first elastic member 32 that acts on the first pressure head 31 and pushes the first pressure head 31 to abut against the partition 2, a second pressure head 33 and a second elastic member 34 that acts on the second pressure head 33 and pushes the second pressure head 33 to abut against the partition 2. The first pressure head 31 and the second pressure head 33 are spaced apart and the gap is larger than the diameter of the second through hole 22. The rotating shaft 4 is rotatably connected inside the outer shell 1 and connected to the adjustment frame 3. The operating component 5 includes a receiving end connected to the rotating shaft 4 and a hand-operated end extending outside the outer shell 1.

[0035] The operating component 5 drives the adjustment frame 3 to move via the rotating shaft 4, so that the first pressure head 31 and the second pressure head 33 respectively close any two of the first through hole 21, the second through hole 22 and the third through hole 23.

[0036] Compared with the prior art, the above solution optimizes the structure of the switching core by designing the adjustment frame 3 to include a first pressure head 31, a first elastic element 32, a second pressure head 33, and a second elastic element 34. The first pressure head 31 and the second pressure head 33 are used to close any two of the first through hole 21, the second through hole 22, and the third through hole 23. The first elastic element 32 and the second elastic element 34 apply elastic thrust to the first pressure head 31 and the second pressure head 33 respectively, ensuring that the first pressure head 31 and the second pressure head 33 are always in contact with the partition plate 2. This ensures that even if the first pressure head 31 and the second pressure head 33 wear, they can still achieve a good sealing effect on the first through hole 21, the second through hole 22, and the third through hole 23, effectively improving their service life.

[0037] Combination Figure 1 and Figure 3As shown, in this embodiment, the outer casing 1 includes an upper casing and a lower casing that are detachably connected, forming a receiving cavity between the upper and lower casings; the switching inner core is located within the receiving cavity. The upper side (i.e., the upper casing) of the outer casing 1 is provided with a water inlet 111 communicating with the water inlet channel 11, the lower side (i.e., the lower casing) of the outer casing 1 is provided with a bubble outlet 121 communicating with the first water outlet channel 12 and a shower outlet 141 communicating with the third water outlet channel 14, and the side of the outer casing 1 is provided with a water purifier 6 communicating with the second water outlet channel 13. The first water outlet channel 12, the second water outlet channel 13, and the third water outlet channel 14 are independent of each other.

[0038] Combination Figure 6 As shown, the water purifier 6 includes a housing 61 and a filter element 62. The housing 61 has an inner cavity and a water inlet 63 and a water outlet 64 that are connected to the inner cavity. The water inlet 63 is connected to the second water outlet channel 13. The water outlet 64 is vertically arranged on the lower side of the housing 61. A base 65 is provided inside the housing 61. The filter element 62 is detachably connected to the base 65 to separate the water inlet 63 and the water outlet 64, so that the water flowing into the inner cavity from the water inlet 63 is filtered by the filter element 62 and then discharged from the water outlet 64.

[0039] Furthermore, the base 65 has a mounting groove 651 in the middle, and the filter element 62 includes a mounting end that is inserted into the mounting groove 651. The mounting groove 651 has a limiting rib 66 parallel to the insertion direction of the filter element 62. The mounting end of the filter element 62 has a limiting groove 621 for the limiting rib 66 to be inserted into. Thus, the mounting end of the filter element 62 is positioned by the cooperation of the limiting rib 66 and the limiting groove 621, so as to avoid misalignment of the mounting end of the filter element 62 during assembly.

[0040] Meanwhile, the side wall of the outer shell 1 located below the partition 2 is provided with a receiving pipe 15. The receiving pipe 15 includes a first end that connects to the water inlet hole 63 and a second end that connects to the second water outlet channel 13. A sealing ring 16 is installed between the first end of the receiving pipe 15 and the shell 61, thereby effectively improving the connection sealing between the water inlet hole 63 and the receiving pipe 15 through the sealing ring 16. The structure is simple and reliable.

[0041] In this embodiment, the operating member 5 is rod-shaped, and the side wall of the outer casing 1 is provided with a long groove 17 for the hand-operated end of the operating member 5 to extend out. When the operating member 5 abuts against one end of the long groove 17, the first through hole 21 and the second through hole 22 are closed. When the operating member 5 abuts against the other end of the long groove 17, the second through hole 22 and the third through hole 23 are closed. When the operating member 5 is located in the middle of the long groove 17, the first through hole 21 and the third through hole 23 are closed. The operation is simple and convenient.

[0042] Regarding the specific forms of the first pressure head 31 and the second pressure head 33, combined with Figures 4-6As shown, in this embodiment, the first pressure head 31 is a first cover parallel to the partition 2. The length of the first cover is greater than the distance between the first through hole 21 and the second through hole 22, thereby achieving simultaneous closure of the first through hole 21 and the second through hole 22. The second pressure head 33 is a second cover parallel to the partition 2. The length of the second cover is greater than the distance between the second through hole 22 and the third through hole 23, thereby achieving simultaneous closure of the second through hole 22 and the third through hole 23. The gap between the first cover and the second cover is greater than the aperture of the second through hole 22. The cap-like structure of the first cover and the second cover can achieve a good sealing effect on the first through hole 21, the second through hole 22 and the third through hole 23, and the structure is reliable.

[0043] Combination Figure 7 As shown, the adjusting frame 3 is provided with a first guide sleeve 35 and a second guide sleeve 36, both perpendicular to the partition 2. The first cover is slidably connected to the lower part of the first guide sleeve 35. The first elastic element 32 is a spring, with its upper end connected to the upper part of the first guide sleeve 35 and its lower part acting on the first cover. The second cover is slidably connected to the lower part of the second guide sleeve 36. The second elastic element 34 is a spring, with its upper end connected to the upper part of the second guide sleeve 36 and its lower part acting on the second cover. Thus, the first cover and the first spring are guided by the first guide sleeve 35, and the second cover and the second spring are guided by the second guide sleeve 36, making the overall structure more reliable.

[0044] Or, such as Figures 8-10 As shown, in another embodiment, the first pressure head 31 consists of two first plugs, and the first elastic element 32 consists of two first springs. The two first springs act on the two first plugs respectively, causing the two first plugs to abut against the partition 2. The distance between the two first plugs corresponds to the distance between the first through hole 21 and the second through hole 22, thereby achieving simultaneous closure of the first through hole 21 and the second through hole 22. The second pressure head 33 consists of two second plugs, and the second elastic element 34 consists of two second springs. The two second springs act on the two second plugs respectively, causing the two second plugs to abut against the partition 2. The distance between the two second plugs corresponds to the distance between the second through hole 22 and the third through hole 23, thereby achieving simultaneous closure of the second through hole 22 and the third through hole 23. Since the first and second plugs are both spherical, they experience rolling friction with the partition 2, thereby ensuring the sealing effect of the first through hole 21, the second through hole 22, and the third through hole 23 while further reducing wear.

[0045] Furthermore, the adjusting frame 3 is provided with two first guide sleeves 35 and two second guide sleeves 36, each perpendicular to the partition plate 2. Two first plugs are slidably connected to the lower parts of the two first guide sleeves 35, and the upper ends of the two first springs are connected to the upper parts of the two first guide sleeves 35, with the lower ends acting on the two first plugs respectively. Two second plugs are slidably connected to the lower parts of the two second guide sleeves 36, and the upper ends of the two second springs are connected to the upper parts of the two second guide sleeves 36, with the lower ends acting on the two second plugs respectively. Thus, the first plugs and the first springs are guided by the first guide sleeves 35, and the second plugs and the second springs are guided by the second guide sleeves 36, making the overall structure more reliable.
