Description

Technical Field

[0001] This utility model relates to the field of water tap technology, and in particular to a valve core and water tap with dual water path switching. Background Technology

[0002] Traditional dual-water-path faucets typically have a two-inlet, one-outlet valve. The first inlet of this valve connects to a hot water inlet pipe, while the second inlet connects to a raw water inlet pipe. A spout is connected to the outlet of the valve via an outlet pipe. However, this dual-inlet, one-outlet valve water-path switching structure integrates both hot and raw water outlets onto a single outlet pipe. When hot water is used after raw water has been drawn, residual raw water from the previous draw may be present in the hot water, which can carry bacteria and reduce the safety of drinking hot water. This design urgently needs improvement. Utility Model Content

[0003] The purpose of this invention is to provide a valve core and faucet with dual water path switching, which can improve water output efficiency and avoid cross-contamination in the water outlet channel.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a valve core with dual water path switching, including a valve seat body, a valve stem assembly rotatably mounted on the valve seat body, and a water path switching seat connected to the output end of the valve stem assembly. The valve seat body has a first water inlet channel, a first water outlet channel, a second water inlet channel, and a second water outlet channel. The liquid inlet of the first water inlet channel, the liquid outlet of the first water outlet channel, the liquid inlet of the second water inlet channel, and the liquid outlet of the second water outlet channel are sequentially adjacent and arranged in a ring. The bottom of the water circuit switching seat is symmetrically provided with a first water passage and a second water passage. The valve stem assembly drives the water circuit switching seat to rotate, so that the first water inlet channel and the first water outlet channel or the second water inlet channel and the second water outlet channel are connected through the first water passage, or the first water inlet channel and the first water outlet channel or the second water inlet channel and the second water outlet channel are connected through the second water passage.

[0005] By adopting the above technical solution, the rotation of the valve stem assembly will drive the water circuit switching seat to rotate, so that the first water inlet channel and the first water outlet channel are connected through the first water passage or the second water passage, or the second water inlet channel and the second water outlet channel are connected through the first water passage or the second water passage, thereby enabling the corresponding water circuits to connect and realize the water outlet function. The liquid inlet of the first water inlet channel, the liquid outlet of the first water outlet channel, the liquid inlet of the second water inlet channel, and the liquid outlet of the second water outlet channel are arranged in a sequentially adjacent and ring-shaped manner, which reduces the travel between the first water inlet channel and the first water outlet channel and between the second water inlet channel and the second water outlet channel, thereby saving water outlet time. Moreover, by setting the dual-channel water outlet structure of the first water outlet channel and the second water outlet channel, the cross-contamination of water sources in the first water outlet channel and the second water outlet channel can be avoided, which has the effect of improving water outlet efficiency and avoiding cross-contamination of water outlet channels.

[0006] A further feature of this invention is that the first water passage and the second water passage are configured as arc-shaped channel structures, and the inlet of the first water inlet channel, the outlet of the first water outlet channel, the inlet of the second water inlet channel, and the outlet of the second water outlet channel are all located on the rotation trajectory of the first water passage and the second water passage, and the first water passage and the second water passage are adjacent to each other and spaced apart at the bottom of the water path switching seat.

[0007] By adopting the above technical solution, the design of the first and second water passages of the arc-shaped channel structure can reduce the impact force of water flow at the bends in the first and second water passages, thereby reducing water outlet noise.

[0008] A further feature of this invention is that the valve seat body includes a valve body, a valve sleeve, and a water distribution seat assembly. A valve cavity is formed between the valve sleeve and the valve body. The valve stem assembly and the water circuit switching seat are rotatably disposed within the valve cavity. The water distribution seat assembly is fixedly installed at the bottom of the valve cavity. The inlet of the first water inlet channel, the outlet of the first water outlet channel, the inlet of the second water inlet channel, and the outlet of the second water outlet channel are all located on the upper surface of the water distribution seat assembly.

[0009] By adopting the above technical solution and utilizing the split-type valve seat main body design, the water distribution seat assembly can independently undertake the flow channel distribution function, extend its service life, and facilitate rapid assembly after processing, reducing the processing difficulty of each water flow channel.

[0010] A further feature of this invention is that the water distribution seat assembly includes an upper water distribution seat and a lower water distribution seat, the first water inlet channel, the first water outlet channel, the second water inlet channel, and the second water outlet channel penetrate the upper and lower end faces of the upper and lower water distribution seats, the water circuit switching seat and the valve sleeve are sealed together by the upper water distribution seat, and the valve sleeve and the valve body are sealed together by the lower water distribution seat.

[0011] By adopting the above technical solution, the upper and lower water distribution seats are designed as separate units with upper and lower layers. This ensures the dynamic sealing between the water circuit switching seat and the upper water distribution seat, while the lower water distribution seat improves the static sealing between the valve sleeve and the valve body. Through the synergistic effect of the upper and lower water distribution seats, a double sealing structure is formed, which improves the sealing effect and extends the service life.

[0012] A further feature of this invention is that: a positioning post is provided at the bottom of the lower water distribution seat, and a positioning groove is provided at the bottom of the valve body in the valve cavity; the positioning post is inserted into the positioning groove for positioning, so that the lower water distribution seat and the valve body are in a non-rotating engagement.

[0013] A further feature of this invention is that the outer wall of the lower water distribution seat is provided with a buckle, and the valve sleeve is provided with a buckle groove corresponding to the buckle. The buckle and the buckle groove are engaged and positioned to prevent the lower water distribution seat from rotating with the valve sleeve.

[0014] By adopting the above technical solution and using a snap-fit ​​method, the assembly speed between the lower water distribution seat and the valve sleeve can be improved.

[0015] A further feature of this invention is that the upper water distribution seat has a slot corresponding to the buckle, and the buckle engages with the slot for positioning, thereby preventing the upper water distribution seat from rotating with the lower water distribution seat.

[0016] A further feature of this invention is that: the upper and lower surfaces of the lower water distribution seat are respectively provided with porous sealing rings, the holes on the porous sealing rings avoid each other with the water inlets and outlets corresponding to the first water inlet channel, the first water outlet channel, the second water inlet channel, and the second water outlet channel, and the upper water distribution seat and the lower water distribution seat, are sealed together by the corresponding porous sealing rings.

[0017] By adopting the above technical solution, the porous sealing ring can improve the water leakage prevention performance of the upper and lower surfaces of the lower water distribution seat.

[0018] Another technology of this utility model is to provide a faucet, including a water supply module, a water purification module and a water outlet module. A hot and cold water switching valve is provided between the water supply module and the water purification module. The water supply module includes a hot water inlet pipe and a raw water inlet pipe. The hot and cold water switching valve is used to switch the connection between the hot water inlet pipe or the raw water inlet pipe and the water inlet of the water purification module. A water path switching valve is connected between the water outlet of the water purification module and the water inlet of the water outlet module. The water path switching valve has the valve core. The water purification module has a purified water flow path and a tap water flow path. The water path switching valve is used to switch the water outlet of the purified water flow path or the tap water flow path to be connected to the water outlet module.

[0019] By adopting the above technical solution, the operator can use the hot and cold water switching valve to allow hot water or raw water to enter, and then use the water circuit switching valve to allow hot water or raw water to selectively enter the purified water flow path or the tap water flow path of the water purification module. When entering the purified water flow path, the hot water or raw water can be purified. When entering the tap water flow path, the hot water or raw water flows directly to the outlet module to achieve water output.

[0020] A further feature of this invention is that the water outlet module has a purified water outlet pipe and a tap water outlet pipe, the outlet end of the purified water outlet pipe is connected to a purified water outlet nozzle, and the outlet end of the tap water outlet pipe is connected to a tap water outlet nozzle.

[0022] In summary, this utility model has the following beneficial effects: The valve seat body has a first inlet channel, a first outlet channel, a second inlet channel, and a second outlet channel. The inlet ports of the first inlet channel, the outlet ports of the first outlet channel, the inlet ports of the second inlet channel, and the outlet ports of the second outlet channel are sequentially adjacent and arranged in a ring. A first water passage channel and a second water passage channel are symmetrically provided at the bottom of the water circuit switching seat. Rotation of the valve stem assembly causes the water circuit switching seat to rotate, thereby connecting the first inlet channel and the first outlet channel through either the first or second water passage channel, or connecting the second inlet channel and the second outlet channel through either the first or second water passage channel. This invention enables the corresponding water channels to be connected to achieve the water outlet function. The inlet of the first water inlet channel, the outlet of the first water outlet channel, the inlet of the second water inlet channel, and the outlet of the second water outlet channel are arranged in a sequentially adjacent and ring-shaped manner. This reduces the travel distance between the first water inlet channel and the first water outlet channel, as well as between the second water inlet channel and the second water outlet channel, thereby saving water outlet time. Furthermore, by setting up a dual-channel water outlet structure with the first and second water outlet channels, cross-contamination of the water sources in the first and second water outlet channels can be avoided, which improves water outlet efficiency and prevents cross-contamination of the water outlet channels.

The valve seat body 1 has a first water inlet channel 11, a first water outlet channel 12, a second water inlet channel 13, and a second water outlet channel 14. The inlet of the first water inlet channel 11, the outlet of the first water outlet channel 12, the inlet of the second water inlet channel 13, and the outlet of the second water outlet channel 14 are sequentially adjacent and arranged in a ring. The bottom of the water circuit switching seat 6 is symmetrically provided with a first water passage 61 and a second water passage 62. The valve stem assembly 5 drives the water circuit switching seat 6 to rotate, so that the first water inlet channel 11 and the first water outlet channel 12 or the second water inlet channel 13 and the second water outlet channel 14 are connected through the first water passage 61, or the first water inlet channel 11 and the first water outlet channel 12 are connected through the first water passage 61, or the first water inlet channel 13 and the second water outlet channel 14 are connected through the first water passage 61. The water channel 11 is connected to the first water outlet channel 12 or the second water inlet channel 13 is connected to the second water outlet channel 14 through the second water passage channel 62. The first water passage channel 61 and the second water passage channel 62 are designed as arc-shaped channel structures. The inlet of the first water inlet channel 11, the outlet of the first water outlet channel 12, the inlet of the second water inlet channel 13 and the outlet of the second water outlet channel 14 are all located on the rotation trajectory of the first water passage channel 61 and the second water passage channel 62. The first water passage channel 61 and the second water passage channel 62 are adjacent to each other and spaced apart at the bottom of the water path switching seat 6. The arc-shaped channel structure of the first water passage channel 61 and the second water passage channel 62 can reduce the impact force of the water flow at the bend in the first water passage channel 61 and the second water passage channel 62, thereby reducing the noise of the water outlet.

The split-type design of the valve seat body 1 allows the water distribution seat assembly 4 to independently perform the flow channel distribution function, extending its service life. It also facilitates rapid assembly after processing, reducing the processing difficulty of each water flow channel. The water distribution seat assembly 4 includes an upper water distribution seat 41 and a lower water distribution seat 42. The first inlet channel 11, the first outlet channel 12, and the second outlet channel 14 are all located on the upper surface of the water distribution seat assembly 4. The two inlet channels 13 and the second outlet channel 14 penetrate the upper and lower end faces of the upper water distribution seat 41 and the lower water distribution seat 42. The water circuit switching seat 6 and the valve sleeve 3 are sealed together by the upper water distribution seat 41, and the valve sleeve 3 and the valve body 2 are sealed together by the lower water distribution seat 42. The upper water distribution seat 41 and the lower water distribution seat 42 adopt a split design with upper and lower layers, which can ensure the dynamic sealing between the water circuit switching seat 6 and the upper water distribution seat 41, while the lower water distribution seat 42 can improve the static sealing between the valve sleeve 3 and the valve body 2. Through the synergistic effect of the upper water distribution seat 41 and the lower water distribution seat 42, a double sealing structure is formed, which improves the sealing effect and extends the service life. In addition, the upper water distribution seat 41 and the lower water distribution seat 42 in this embodiment are both made of wear-resistant ceramic material to reduce the functional load of both and extend their service life.

The upper water distribution seat 41 has a buckle groove 411 corresponding to the buckle 422. 22 engages with the slot 411 for positioning, preventing the upper water distribution seat 41 from rotating with the lower water distribution seat 42; the upper and lower surfaces of the lower water distribution seat 42 are respectively provided with multi-hole sealing rings 43, the holes on the multi-hole sealing rings 43 are mutually abutting with the inlet and outlet of the first water inlet channel 11, the first water outlet channel 12, the second water inlet channel 13 and the second water outlet channel 14, and the upper water distribution seat 41 and the lower water distribution seat 42 are sealed with the corresponding multi-hole sealing rings 43, the multi-hole sealing rings 43 can improve the water leakage prevention performance of the upper and lower surfaces of the lower water distribution seat 42.

The liquid inlet of the first water inlet channel 11, the liquid outlet of the first water outlet channel 12, the liquid inlet of the second water inlet channel 13 and the liquid outlet of the second water outlet channel 14 are arranged in a sequentially adjacent and ring-shaped manner, which reduces the travel between the first water inlet channel 11 and the first water outlet channel and between the second water inlet channel 13 and the second water outlet channel 14, thereby saving water outlet time. Moreover, by setting the dual-channel water outlet structure of the first water outlet channel 12 and the second water outlet channel 14, the cross-contamination of water sources in the first water outlet channel 12 and the second water outlet channel 14 can be avoided, which has the effect of improving water outlet efficiency and avoiding cross-contamination of water outlet channels.
