Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

An embodiment of the utility model provides a tap. The faucet can be matched with a water purifier for application. The user can utilize the tap to take the purified water produced by the water purifier.

As shown in fig. 1, the faucet 100 includes a main body 200, and a raw water inlet 310, a raw water outlet 320, a pure water inlet 330, and a pure water outlet 340 provided on the main body 200. A raw water passage 410 is provided between the raw water inlet 310 and the raw water outlet 320. A pure water passage 420 is provided between the pure water inlet 330 and the pure water outlet 340. A valve 510 is also provided in the raw water passage 410. The valve 510 may be a butterfly valve, ball valve, spool valve, or the like.

A sensing device is further disposed in the main body 200 of the faucet 100, and the sensing device is used for respectively sending corresponding electric signals to the water purifier when the valve 510 is opened and closed so as to control the water purifier. Alternatively, the sensing device may detect the position of the valve 510 and send a corresponding electrical signal according to the detection result. In one embodiment, the electrical signals may include a start water intake electrical signal and a stop water intake electrical signal for the water purifier. For example, when the valve 510 is opened, raw water may enter the water purifier through the raw water passage 410. The sensing device detects that the valve 510 is opened, and the sensing device can send a signal of starting to take water to the water purifier. After the water purifier receives the electric signal for starting to take water, the water purifying action of the water purifier can be carried out. When the valve 510 is closed, the raw water is stopped at the valve 510 in the raw water passage 410. The sensing device detects that the valve 510 is closed, and the sensing device can send a signal to stop getting water to the water purifier. After the water purifier receives the water taking stopping electric signal, the water purifying action of the water purifier can be stopped. Because the water purification action and the water purification stopping action of each water purifier are different, the electric signal sent to the water purifier by the induction device can only control the water purifier to start to perform the actions, and the specific water taking action, the content of the water taking stopping action and the time delay condition are determined and executed by the controller of the water purifier.

A detailed description of the faucet 100 according to one embodiment of the present invention follows. The raw water inlet 310 of the faucet 100 may be used to connect a tap water pipe, the raw water outlet 320 may be used to connect the raw water inlet 601 of the water purifier, and the pure water inlet 330 may be used to connect the pure water inlet 602 of the water purifier. When the valve 510 is closed, the faucet 100 is also in a closed state. At this time, the raw water passage 410 between the raw water inlet 310 and the raw water outlet 320 is blocked, that is, the tap 100 is blocked between the tap water pipe and the raw water inlet 601 of the water purifier. When the valve 510 is opened, the faucet 100 is also in an open state. At this time, the raw water passage 410 between the raw water inlet 310 and the raw water outlet 320 communicates, that is, the tap water pipe communicates with the raw water inlet 601 of the water purifier through the faucet 100, and raw water can enter the water purifier through the faucet 100. The valve 510 can connect and disconnect the tap water pipe and the water purifier inside the faucet 100 through a physical structure. At the same time, the sensing device in the main body 200 of the faucet 100 can send corresponding electrical signals to the water purifier when the valve 510 is opened and closed. The water purifier can complete the action corresponding to the electric signal according to the received electric signal, such as starting or stopping water purification. It can be understood that, when the valve 510 is closed, since the raw water path 410 is blocked, the pressure of the tap water cannot be transmitted to the downstream of the valve 510. Thus, even if the pure water passage is always connected, no pure water flows out of the pure water outlet 340. In other words, the faucet 100 does not have a valve in the pure water passage, but it allows the user to smoothly take water and stop taking water using the faucet 100.

The faucet 100 with the structure can connect and cut off the raw water inlet 310 and the raw water outlet 320, and can control the water inlet of the connected water purifier through the induction device when the connection and the cut-off are performed. Through the arrangement of the faucet 100, when water is taken, the faucet 100 is opened, the raw water channel 410 in the faucet 100 is communicated, and the water purifier is controlled to start water production; when the water intake is stopped, the faucet 100 is closed, the raw water passage 410 in the faucet 100 is cut off, and the water purifier is controlled to stop water production. First, by connecting the faucet 100, the valve 510 can be used as not only the water outlet control device of the water purifier, but also the water inlet electromagnetic valve of the water purifier. Therefore, the structure in the water purifier can be simplified, the water leakage probability is reduced, the reject ratio of products is reduced, and the cost of the products is also reduced. Secondly, the valve in the water route is because of closing too fast, because of the inertia of pressure rivers, rivers will cause the impact to the valve, also take place the water hammer phenomenon promptly. In the purifier that has the solenoid valve of intaking, the water hammer phenomenon can take place in the upstream of the solenoid valve of intaking more, and in the purifier, the upstream of the solenoid valve of intaking still can set up leading filter core more, so leading filter core receives the damage easily under the influence that receives the water hammer phenomenon, reduces its life. Although the water hammer phenomenon is unavoidable, it only occurs upstream of the valve 510 of the faucet 100, so that the water purifier connected downstream of the faucet 100 is not damaged, and the front filter element in the water purifier is not damaged. Third, since the faucet 100 is typically located on the counter top of a cabinet when in use, once a water leak occurs, the user can detect it in time, avoiding greater losses. Fourthly, if the water purifier itself connected with the tap 100 or the internal elements of the water purifier are maintained and replaced, the tap 100 is only required to be closed, the function of stopping the tap water can be achieved, an additional valve at the upper part of the water purifier does not need to be closed as in the prior art, the valve is reduced, and the use cost of the product is indirectly reduced. Fifthly, only one valve is arranged in the faucet 100, so that the control is easy and the cost is low.

Illustratively, the valve 510 may include an operator and a valve cartridge (not shown). The operating member is used to change the position of the spool in response to a user operation. In the embodiment illustrated in FIG. 1, the operating member may be a handle of a faucet. The operating member may also be a water flow switch or the like. The sensing means may be a position sensor for sending a corresponding electrical signal when the valve is open and closed by sensing the position of the spool or the operating member, respectively. Taking the operating member as a handle of the faucet as an example, a user opens or closes a valve of the faucet by moving the handle. In other words, the handle of the faucet will move when the valve of the faucet is opened or closed. The sensing device can be used for detecting the position of the handle and sending a corresponding electric signal according to the detection result of the position of the handle. If the operating part is a water flow switch key, the valve core can be connected with the electromagnet, and the water flow switch key can control the generation or disappearance of the magnetic field of the electromagnet, so that the valve core is controlled to move by magnetic force, and the opening and closing of the faucet are realized. The sensing device may send an electrical signal based on the detection of the position of the spool.

Illustratively, the position sensor may be a micro switch or a proximity switch. The micro-switch is a contact switch, and in one embodiment, the operating member is a handle of the faucet, and the micro-switch is connected to the handle of the faucet and is touched by movement of the handle of the faucet. Alternatively, the micro switch may be connected to a valve cartridge of the faucet, and the micro switch is touched by movement of the valve cartridge. The micro switch has small volume and can reduce the size of the faucet. The proximity switch is a non-contact switch that may be located inside the faucet. Similar to the micro switch which can detect the position of the handle or the valve core, the difference is that the proximity switch can send corresponding electric signals under the condition of not touching, so the abrasion between parts can be reduced, and the service life of the faucet is prolonged.

Illustratively, the valve 510 is a solenoid valve, the sensing device is a body proximity sensor, and the body proximity sensor is electrically connected to the valve 510. The sensing means senses the opening and closing of the valve 510 using the human body of the user. The sensing device may include a photosensor, a thermal imaging sensor, a camera, etc. In one embodiment, the body sensing means may comprise an infrared sensor, which is provided on the tap. When a user approaches the faucet, the infrared sensor detects that a human body exists, and the control valve 510 is opened; when it is detected that the human body leaves the preset area, the valve 510 is controlled to be closed. The principle of opening and closing the solenoid is well known to those skilled in the art and will not be described in detail. The sensing device controls the valve 510 to open or close, and at the same time, controls the water purifier to perform corresponding actions. Therefore, the induction device is a human body proximity sensor, so that the faucet has an automatic induction function, a user can control the faucet without contacting the faucet, and the use experience is improved. The human body proximity sensor is set as an infrared sensor, the principle is simple, and the cost is low.

According to another aspect of the utility model, still provide a water purification system. As shown in fig. 2, the water purification system includes a water purifier 600, and the water purifier 600 is provided with a raw water port 601 and a pure water port 602. The water purification system further comprises the faucet 100 described above. The raw water outlet 320 of the tap 100 is communicated with the raw water port 601 of the water purifier, and the pure water inlet 330 of the tap 100 is communicated with the pure water port 602 of the water purifier.

As described above, the valve 510 of the faucet 100 may control the raw water passage 410, thereby controlling the communication of raw water with the water purifier. Thus, the water purification system can use the faucet 100 to replace the existing water inlet solenoid valve and serve as the water outlet control device of the water purifier 600. This may simplify the control logic on the one hand. On the other hand, because the setting of the solenoid valve of intaking has been reduced, not only reduced water purification system's fault rate and can also reduced water purification system's cost. Moreover, the raw water passage 410 is disposed on the faucet 100, and the water hammer phenomenon can only occur at the upstream of the faucet 100, so that the water hammer phenomenon does not damage the water purifier, thereby protecting the water purifier and prolonging the service life of the water purifier. Finally, the faucet 100 is positioned on the counter top of the cabinet during use, rather than inside the cabinet as with the water purifier 600, to facilitate user detection if a water leak occurs.

Illustratively, a booster pump 610 and a reverse osmosis filter element 620 are further arranged in the water purifier 600. The water inlet of the booster pump 610 is communicated with the raw water port 601 of the water purifier 600, the water outlet of the booster pump 610 is communicated with the raw water end 621 of the reverse osmosis filter element 620, and the pure water end 622 of the reverse osmosis filter element 620 is communicated with the pure water port 602 of the water purifier 600. The booster pump 610 is electrically connected to the sensing device of the faucet 100.

When the valve 510 of the faucet is opened, the booster pump 610 can be controlled by the sensing device to increase the water pressure in the pipeline of the water purifier 600. The raw water with high water pressure is pressed into the reverse osmosis filter element 620 through the raw water end 621, and the pure water generated after filtration is discharged through the pure water end 622 and flows to the pure water port 602 of the water purifier 600. When the valve 510 of the faucet is closed, the booster pump 610 can be controlled by the sensing device to end the operation, thereby no longer pressurizing the water circuit and equipment downstream thereof. The reverse osmosis filter element 620 is pressurized without external force, wherein the raw water after the membrane will not flow to the front of the membrane. In other words, even if there is a pure water passage in the faucet that is not provided with any valve, no pure water will flow out of the pure water outlet of the faucet after the valve 510 of the faucet is closed. Purifier 600 with reverse osmosis filter core, filterable impurity range is extensive, and the pure water quality of water of preparing is better, has improved the user and has experienced purifier 600's use. The booster pump 610 is electrically connected with the sensing device, and the booster pump 610 can be directly controlled through a faucet, so that the logic is simple and the implementation is easy.

Illustratively, the water purifier 600 further includes a concentrate line 630 and a waste water solenoid valve 640. The concentrated water pipeline 630 is communicated with a concentrated water end 623 of the reverse osmosis filter element 620, and the wastewater solenoid valve 640 is arranged on the concentrated water pipeline 630. The waste water solenoid valve 640 is electrically connected to the sensing device. The concentrated water pipeline 630 is used for discharging the wastewater generated after the reverse osmosis filter element 620 filters, and the wastewater electromagnetic valve 640 arranged on the concentrated water pipeline 630 can play a role in communicating and stopping the concentrated water pipeline 630. As with one embodiment described above, the sensing device may be a position sensor, which is a micro switch connected to the handle of the faucet. When the handle of the faucet is moved to open the faucet, the microswitch is triggered, and an electric signal for starting water taking is sent to the water purifier. After receiving the electric signal, the water purifier controls the booster pump 610 to start and also controls the wastewater solenoid valve 640 to communicate. Thus, the wastewater generated by the reverse osmosis filter element 620 during the water preparation can be discharged through the concentrate line. When the handle of the faucet is moved to close the faucet, the micro switch can send an electric signal for stopping water taking to the water purifier. The water purifier controls the booster pump 610 to stop after receiving the electric signal, and can also control the waste water electromagnetic valve 640 to stop. Therefore, the condition that the pressure of the water purifier is released due to the leakage of the water reserved in the water purifier through a concentrated water pipeline can be prevented. And then avoided the user when next time getting water, just can receive and get the pure water after the water pressure that needs to wait for in the purifier rises. It is understood that the waste water solenoid valve 640 has various types, and its operation varies according to different water purifiers and different programs, and its operation principle and function are well known to those skilled in the art and will not be described in detail.

Therefore, by the arrangement, the induction device can control the wastewater electromagnetic valve 640, so that the functions of the water purifier are increased, and the user experience of the water purifier is improved.

Illustratively, water purifier 600 also includes a master control device. The booster pump 610 is electrically connected to the sensing device via a main control device. The waste water solenoid valve 640 is also electrically connected to the sensing device via a master control device. The main control device is used for controlling the booster pump 610 to be started or closed and controlling the wastewater electromagnetic valve 640 to be opened or closed according to the electric signal received by the self-induction device.

The main control device can be built by adopting electronic elements such as a comparator, a register, a digital logic circuit and the like, or can be realized by adopting processor chips such as a singlechip, a microprocessor, a Programmable Logic Controller (PLC), a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), a Programmable Logic Array (PLA), an Application Specific Integrated Circuit (ASIC) and the like and peripheral circuits thereof.

Therefore, the water purifier 600 with the main control device can automatically control each device including the booster pump 610 and the wastewater solenoid valve 640 in the water purifier 600 through the main control device, and the automation degree of the water purifier is improved.
