Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, specifically a faucet water purifier. Background Technology

[0002] As living standards continue to improve, people have higher and higher requirements for drinking water quality. Faucet water purifiers, as a type of water purification device installed on faucets, are becoming increasingly popular due to their ease of installation and ability to directly filter water flowing from the faucet.

[0003] Existing faucet water purifiers typically include an outer casing and a water circuit switching valve and a water purification filter cartridge installed inside the casing. The top of the casing has a water inlet, and the bottom has a raw water outlet and a purified water outlet. During installation, the faucet is connected to the water inlet. When the raw water passes through the water circuit switching valve, it can flow directly out from the raw water outlet, or it can be filtered by the water purification filter cartridge before flowing out from the purified water outlet.

[0004] The water filter cartridge in a faucet water purifier is a consumable that needs to be replaced regularly. However, different users have different usage patterns, and it is difficult for users to accurately determine whether the filter needs to be replaced based on usage time. If the filter cartridge is forgotten or replaced too late, it can easily lead to secondary pollution of drinking water. If it is replaced too early, it will result in waste of consumables. Therefore, it is necessary to install a filter cartridge replacement reminder device in the use of faucet water purifiers to remind users to replace the filter cartridge in time. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a faucet water purifier that can display the service life of the filter element so that users can replace the filter element in a timely manner.

[0006] The technical solution of this utility model is to provide a faucet water purifier with the following structure: The device includes a housing, a switching valve assembly, and a water purification filter cartridge disposed within the housing. The housing contains an inlet channel, a raw water channel, and a purified water channel connected to the switching valve assembly. The switching valve assembly connects the inlet channel to either the raw water channel or the purified water channel. The water purification filter cartridge is disposed in the purified water channel and filters the flowing raw water. A power generation module with an impeller is disposed within the housing and rotates in the purified water channel, driving the power generation module to generate electricity. A filter cartridge life display module is also disposed on the housing and electrically connected to the power generation module, displaying the filter cartridge's lifespan.

[0007] After adopting the above structure, the faucet water purifier of this utility model has the following advantages compared with the prior art: This utility model features a power generation module and a filter life display module on the housing. When the faucet water purifier is turned on and switched to the water purification mode, the inlet channel is connected to the purification channel. The raw water flowing in from the faucet enters the purification channel and drives the impeller to rotate as it flows through it. The rotation of the impeller drives the power generation module to generate electricity. The power generation module is electrically connected to the filter life display module, which can drive the filter life display module to operate, thereby displaying the lifespan of the filter and reminding the user to replace the water purification filter in time.

[0008] Preferably, the switching valve assembly includes a valve seat and a valve core. The valve seat has a valve cavity, and the inlet water channel, raw water channel, and purified water channel are connected to the valve cavity. The valve core is rotatably connected in the valve cavity to connect the inlet water channel with the raw water channel or the purified water channel.

[0009] Preferably, the valve core has an inner cavity with an opening on one side wall. Three protrusions are evenly spaced in a ring on the side wall of the valve cavity facing the opening. The outer edge of the opening abuts against the protrusions, creating a gap between the side wall of the valve core and the side wall of the valve cavity. This allows the water inlet channel to communicate with the inner cavity of the valve core, while reducing friction between the valve core and the side wall of the valve cavity during rotation. A sealing gasket is located below the valve core and fits against its outer peripheral wall. A protrusion is located on the side wall of the valve cavity below the protrusions, with the outer end face of the protrusion abutting against the side wall of the sealing gasket.

[0010] The outer wall of the valve core is also provided with a first through hole and a second through hole that communicate with its inner cavity. The first through hole and the second through hole are staggered. When the valve core rotates to the point where the first through hole communicates with the raw water channel, the second through hole is staggered with the clean water channel. At this time, the water in the inlet channel enters its inner cavity through the valve core opening and then flows into the raw water channel through the first through hole. When the valve core rotates to the point where the second through hole communicates with the clean water channel, the first through hole is staggered with the raw water channel. At this time, the water in the inlet channel enters its inner cavity through the valve core opening and then flows into the clean water channel through the second through hole.

[0011] Preferably, the power generation module includes a housing and a power generation module. The housing is cylindrical and has an internal partition that divides it into a front chamber and a rear chamber. The power generation module is located in the rear chamber, and the impeller is rotatably connected to the front chamber and driven by the power generation module. The impeller shaft must be waterproof when passing through the partition to prevent water flowing through the front chamber from entering the rear chamber.

[0012] Preferably, the side wall of the outer casing is provided with at least one water inlet hole communicating with the front chamber. The raw water flowing into the purified water channel through the second through hole enters the front chamber through the water inlet hole, and after driving the impeller to rotate, it flows out through the water outlet hole on the front end face of the front chamber.

[0013] Preferably, the valve seat has a power generation capacitor placement cavity on one side of the valve cavity, and the power generation module is disposed in the power generation capacitor placement cavity.

[0014] Preferably, the filter cartridge life display module includes a timing module and several indicator lights. The timing module is electrically connected to the power generation module and the indicator lights, respectively. It starts timing when the power generation module supplies power, and displays the timing result through the indicator lights. The power generation module only supplies power to the timing module when water flows through the impeller in the purified water channel. Therefore, the timing module can accurately record the usage time of the water filter cartridge and display it through the indicator lights. Three indicator lights can be set: two green lights and one red light. When the red light is on, it indicates that the water filter cartridge's lifespan has ended, thus reminding the user to replace the water filter cartridge in time.

[0015] Preferably, the housing is also equipped with a reset switch, which is electrically connected to the timing module and used to reset the timing module. After replacing the water filter cartridge, the timing module can be reset via the reset switch for convenient reminders for the next replacement.

[0016] Preferably, a blue light antibacterial lamp is installed on the water purification channel near the water outlet to inhibit bacteria near the water outlet and prevent the water at the water outlet from being contaminated.

[0017] Preferably, a switching knob is rotatably connected to one side of the housing. The rotating shaft of the switching knob is connected to the valve core to drive the valve core to rotate. A spring pin is provided on one end face of the housing facing the switching knob. The switching knob is provided with multiple grooves that match the spring pin. The end of the spring pin can be engaged in one of the grooves to serve as a gear position, so that the user can feel that the switching knob is turned in place when turning it.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. At the same time, the terms "first", "second", etc., are only used to distinguish the names of various components and do not have a primary or secondary relationship. Therefore, they should not be construed as limitations on this utility model.

[0028] like Figures 1-7 As shown, this utility model discloses a faucet water purifier: including a housing 1 and a switching valve assembly 2 and a water purification filter element 3 disposed in the housing 1; the housing 1 is provided with an inlet channel 11, a raw water channel 12 and a purified water channel 13 connected to the switching valve assembly 2, the switching valve assembly 2 is used to connect the inlet channel 11 with the raw water channel 12 or the purified water channel 13, and the water purification filter element 3 is disposed on the purified water channel 13 for filtering the raw water flowing through it.

[0029] The switching valve assembly 2 includes a valve seat 21 and a valve core 22. The valve seat 21 has a valve cavity 211. The inlet water channel 11, the raw water channel 12, and the purified water channel 13 are connected to the valve cavity 211. The valve core 22 is rotatably connected in the valve cavity 211 to connect the inlet water channel 11 with the raw water channel 12 or the purified water channel 13.

[0030] The valve core 22 has an inner cavity 221, and an opening is provided on one side wall of the inner cavity 221. Three protrusions 213 are provided on the side wall of the valve cavity 211 facing the opening, and are evenly spaced in a ring. The outer edge of the opening abuts against the protrusions 213, so that the side wall of the valve core 22 and the side wall of the valve cavity 211 are separated, thereby allowing the water inlet channel 11 to communicate with the inner cavity 221 of the valve core 22. A sealing gasket 23 is provided below the valve core 22 and fits against its outer peripheral wall. A protrusion 214 is provided on the side wall of the valve cavity 211 below the protrusions 213, and the outer end face of the protrusion 214 abuts against the side wall of the sealing gasket 23. The outer wall of the valve core 22 is also provided with a first through hole and a second through hole communicating with its inner cavity 221. The first through hole and the second through hole are staggered. When the valve core 22 rotates to the point where the first through hole communicates with the raw water channel 12, the second through hole is staggered with the clean water channel 13. At this time, water from the inlet channel 11 enters its inner cavity 221 through the opening of the valve core 22, and then flows into the raw water channel 12 through the first through hole. When the valve core 22 rotates to the point where the second through hole communicates with the clean water channel 13, the first through hole is staggered with the raw water channel 12. At this time, water from the inlet channel 11 enters its inner cavity 221 through the opening of the valve core 22, and then flows into the clean water channel 13 through the second through hole. The valve seat 21, the valve core 22, and the sealing gasket 23 are conventional technologies and will not be described in detail here.

[0031] like Figures 2-7 As shown, the housing 1 is equipped with a power generation module 4, which has an impeller 41. The impeller 41 is installed on the water purification channel 13 and rotates when the raw water flows through it, thereby driving the power generation module 4 to generate electricity. The housing 1 is also equipped with a filter life display module 5, which is electrically connected to the power generation module 4 and is used to display the service life of the filter.

[0032] The power generation module 4 includes a housing 42 and a power generation module 43. The housing 42 is cylindrical and has an internal partition 421 that divides it into a front chamber 422 and a rear chamber 423. The power generation module 43 is located in the rear chamber 423. The impeller 41 is rotatably connected to the front chamber 422 and is driven by the power generation module 43. The shaft of the impeller 41 must be waterproof when passing through the partition 421 to prevent water flowing through the front chamber 422 from entering the rear chamber 423. The impeller 41 and the power generation module 43 can also be driven by a magnetic coupling. The partition 421 completely separates the front chamber 422 and the rear chamber 423, further improving waterproofing.

[0033] The side wall of the outer casing 42 is provided with at least one water inlet hole 424 communicating with the front chamber 422, for supplying raw water into the front chamber 422. After driving the impeller 41 to rotate, the water flows to the water purification filter element 3 through the water outlet hole 425 on the front end face of the front chamber 422.

[0034] A power generation capacitor placement cavity 212 is provided on one side of the valve cavity 211 on the valve seat 21, and the power generation module 4 can be placed in the power generation capacitor placement cavity 212.

[0035] like Figure 7 As shown, the filter life display module 5 includes a timing module 51 and several display lights 52. The timing module 51 is electrically connected to the power generation module 4 and the display lights 52 respectively. It performs timing when the power generation module 4 supplies power and displays the timing result through the display lights 52.

[0036] When the water in the water purification channel 13 flows through the impeller 41, the power generation module 4 will supply power to the timing module 51. Therefore, the timing module 51 can accurately record the usage time of the water purification filter 3 and display it through the indicator light 52. The indicator light 52 can be set to three, two green lights and one red light. When the red light is on, it indicates that the service life of the water purification filter 3 has ended, thus reminding the user to replace the water purification filter 3 in time.

[0037] The housing 1 is also equipped with a reset switch 6, which is connected to the timing module 51 wire. After the water filter element 3 is replaced, the timing module 51 can be reset by the reset switch 6 to facilitate the next replacement reminder.

[0038] like Figure 2 and Figure 7 As shown, a blue light antibacterial lamp 7 is installed on the water purification channel 13 near the water outlet to inhibit bacteria near the water outlet and prevent the water at the outlet from being contaminated. The blue light antibacterial lamp 7 can be powered by the power generation module 4, or by an external or built-in power supply.

[0039] For example Figure 1 , Figure 2 and Figure 7 As shown, a switching knob 8 is rotatably connected to one side of the housing 1. The rotating shaft of the switching knob 8 is connected to the valve core 22 and is used to drive the valve core 22 to rotate.

[0040] The housing 1 has a spring pin 9 on one end face facing the switching knob 8. The switching knob 8 has multiple grooves 81 that match the spring pin 9. The end of the spring pin 9 can be engaged in one of the grooves 81 to serve as a gear position, so that the user can feel that the switching knob 8 is turned in place when turning it.

[0041] The faucet water purifier of this utility model has a power generation module 4 installed inside the housing 1 and a filter life display module 5 installed on the housing 1. When the faucet water purifier is turned on and switched to the water purification mode, the water inlet channel 11 is connected to the water purification channel 13. The raw water flowing in from the faucet will enter the water purification channel 13 and drive the impeller 41 to rotate when it flows through the impeller 41. When the impeller 41 rotates, it will drive the power generation module 4 to generate electricity. The power generation module 4 is electrically connected to the filter life display module 5 and can drive the filter life display module 5 to operate, thereby displaying the service life of the filter and reminding the user to replace the water purification filter 3 in time to avoid secondary pollution of the purified water.

[0042] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
