Description

Technical Field

[0001] The present invention relates to the technical field of drinking water purification equipment manufacturing, in particular to a faucet and a water purifier. Background Art

[0002] The outlet of a water purifier is typically equipped with a faucet. Single kitchen sinks often have limited installation space, often requiring additional mounting space by drilling holes in the countertop. This can leave holes after the faucet is later removed, and harmful substances such as rust and bacteria can be found in the pipes and faucets, which are released during water use. Existing water purifiers are typically equipped with a single faucet, which is limited in application scenarios and can only be used with single-outlet models. Once the water purifier is replaced, it can only be retired along with the entire unit. Commonly used mechanical faucets in households manually rotate the handle to drive the mechanical valve core, which then seals the water through a ceramic seal. The ceramic seal gradually wears out during use, causing the seal to fail and leak. Summary of the Invention

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, as long as no conflict exists, the various embodiments of the present invention and the various features in the embodiments can be combined with each other, and the resulting technical solutions are all within the scope of protection of the present invention.

[0032] Parts not described in the present invention can be implemented by adopting or drawing on existing technologies.

[0033] like Figure 1 As shown, the faucet 1 of the present invention includes a faucet body 11, a sterilization module 12 connected to the faucet body 11, and a water outlet control module 2, wherein the faucet body 11 includes a water outlet 111 and a control panel 113, the water outlet control module 2 is independent of the faucet body 11, and the control panel 113 is electrically connected to the water outlet control module 2.

[0034] The faucet of the present invention is equipped with an independent external power supply and an independent water outlet control device, so that the faucet is no longer limited to being used with a matching water purifier, and can still be used with other models after the original model is replaced.

[0035] Continue to see Figure 1 At least one water outlet port and at least two water inlets are provided in the sterilization module 12. The water outlet port is connected to the water outlet 111 of the faucet body 11 through a water outlet hose 112. At least two water inlets are connected to the water outlet port, and the water inlet channels of at least two water inlets are independent of each other.

[0036] like Figure 2 As shown, in a preferred embodiment, the water outlet control module 2 includes a shell 21 and a base plate 26, and a control board 29, a waterway board assembly 25, and a first control 211 and a second control 27 for controlling the on and off of the waterway are provided on the base plate 26. The waterway board assembly 25 is located between the first control 211 and the second control 27, and is used to control the waterway flow channels of clean water and pure water respectively. The control board 29 is used to receive control signals to control the first control 211 and the second control 27; the waterway board assembly 25 includes a flow counting module for calculating the flow value.

[0037] Preferably, the sterilization module 12 is an ultraviolet sterilization module, such as Figure 3-Figure 5As shown, the UV sterilization module includes an anti-transmission housing 121 and a UV chamber 122 disposed within the anti-transmission housing 121. A water outlet port 123 is disposed within the anti-transmission housing 121 and adjacent to the UV chamber 122. A UV lamp and a sterilization channel are located within the UV chamber 122. The UV lamp is positioned along the sterilization channel, which is defined by the vertically extending space between the UV lamp and the UV chamber 122. The sterilization channel is connected to the water outlet port 123. The UV sterilization module's proximity to the water outlet port ensures minimal residual water flow when the module is turned on. Residual water flow is the water remaining in the pipeline between the UV sterilization module and the faucet outlet after the last drain. The closer the UV sterilization module is to the water outlet port, the less intermediate pipeline there is, resulting in less residual water.

[0038] like Figure 4 and Figure 5 As shown, the sterilization module is provided with a water outlet port 123, a clean water inlet 124, a pure water inlet 126 and a cooked water inlet 125. The three water inlets are connected to the water outlet port 123 respectively, and the clean water inlet 126 is connected to the clean water inlet channel 128, the pure water inlet 126 is connected to the pure water inlet channel 129, and the cooked water inlet 125 is connected to the cooked water inlet channel 127. Figure 6 and Figure 7 As shown, the clean water inlet channel 128 and the pure water inlet channel 121 are spiral channels formed outside the cooked water inlet channel 127. The waterway plate assembly 25 can be connected to the three water inlet channels respectively through a PE tube (cold water channel) and a heat-resistant silicone tube (hot water channel). In this way, the design of independent water outlet pipes is adopted. The three water inlet channels of the clean water inlet channel, the pure water inlet channel and the cooked water outlet pipe are independent of each other and do not interfere with each other, which can ensure that the water flow that does not pass through the sterilization module will not be mixed. In addition, the faucet of the present application can not only be used with a water purifier, but also can be directly connected to the tap water as an ordinary faucet, which has more uses.

[0039] In a preferred embodiment, check valves 28 are provided between the waterway plate assembly 25 and the first control 211, and between the waterway plate assembly 25 and the second control 27. Preferably, the first control 211 and the second control 27 are solenoid valves. Pilot-operated solenoid valves control the waterway on and off. If the valves fail, only water will be sealed off, without causing water leakage.

[0040] The control board 29 receives the processing signal from the control panel and controls the on and off of the control components. The external pure water filtered by the reverse osmosis membrane passes through the second control 27, preferably the second valve body, and is controlled by its on and off; the external clean water purified by ultrafiltration or other non-reverse osmosis methods passes through the first control 211, preferably the first valve body, and is controlled by its on and off.

[0041] like Figure 2 and Figures 8-11As shown, in a preferred embodiment, the flow counting module includes a flow counter 23 and a flow rotor 22 for calculating the outlet flow of clean water and pure water. The flow rotor 22 is arranged at a position close to the water outlet of the waterway plate, and the flow counter 23 is arranged outside the pipeline and electrically connected to the controller of the water outlet control module.

[0042] In this embodiment, the flow technology module is a separate flow rotor and flow counter, which can make the assembly position more flexible and reduce the cost. In other embodiments, the flow counting module can also be an integrated flow meter.

[0043] After the first control 211 or the second control 27 is opened, the water flows through the check valve 28 first, and then drives the rotor 22 to rotate when flowing through the flow rotor 22. The flow counter 23, which is preferably a Hall counter, receives the signal of the flow rotor 22 and feeds it back to the controller, and calculates the flow value through internal logic. Then the water flows into the clean water inlet and the pure water inlet respectively, and flows out from the water outlet after ultraviolet sterilization.

[0044] Due to the presence of water pipes, water purifiers often have a section of water that passes through the filter but does not flow out. After a period of storage, bacterial colonies may grow in the water. The internal piping of different models varies. The sterilization module needs to be briefly activated for the pure water entering the water purifier. The flow meter calculates and feedback to effectively sterilize the water where bacterial colonies are breeding, and the UV module is shut off at the appropriate time to extend the life of the components.

[0045] In a more preferred embodiment, the water outlet control module further includes a TDS probe 24 for monitoring water quality. The TDS probe 24 is disposed on the waterway plate assembly 25 .

[0046] The first control 211 and the ultraviolet sterilization lamp in the sterilization module 12 have the logic of turning on and off at the same time, ensuring that the purified water or tap water must first undergo ultraviolet sterilization before being released through the water outlet, ensuring that the bacterial colony in the water outlet is at a low level that is drinkable. At the same time, a TDS probe is set in the channel to detect the water quality and determine the quality of the water body. For poor water quality, the power of the ultraviolet module is changed to increase the ultraviolet output to ensure the safety of the water outlet. At the same time, there is a timer function in the control program of the ultraviolet sterilization module. It counts from the last time the ultraviolet module was used. If the cumulative time exceeds T1, it is determined that it has not been used for a long time. At this time, the controller controls the ultraviolet module to turn on and sterilize the pipeline.

[0047] In one embodiment, the first control and / or the second control is a solenoid valve, an electric ball valve, or a multi-speed flow valve.

[0048] In one embodiment, the faucet is also equipped with an external independent power supply and a power adapter 30, so that the faucet is no longer limited to being used with a matching water purifier, and can even be used alone without a water purifier. Compared with other products, the scope of use is wider and the use environment is more flexible.

[0049] The present invention also provides a water purifier comprising the above-mentioned faucet, which also has all the beneficial effects of the above-mentioned faucet.
