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.

As shown in fig. 1, the present invention provides a water purifier 100, the water purifier 100 includes a water inlet 110 and a water outlet 120, the water purifier 100 further includes a main water pipeline 200, and the main water pipeline 200 is connected between the water inlet 110 and the water outlet 120. The main water lines 200 are the main water production and water intake lines of the water purifier 100. The main water line 200 includes a booster pump 210, a reverse osmosis filter element 220, a check valve 230, and a high pressure switch 240, which are sequentially disposed along the direction of water flow.

The main water line 200 communicates to the water outlet 120. The user can receive direct drinking water through the water outlet 120. The water outlet 120 may communicate with a mechanical faucet or an electrically controlled water valve. For clarity of the following description, the main water line 200 is divided into a water production line section at the front stage and a water intake line section 201 at the rear stage by a check valve 230. The water intake section 201 communicates to a water outlet 120 of a user, such as a faucet or a line machine.

The function of the booster pump 210 is to increase the pressure of the water entering the water purifier 100, so that the water with a certain pressure passes through the reverse osmosis filter element 220 and is filtered by the reverse osmosis filter element 220 to generate drinkable direct drinking water. The produced direct drinking water flows out of the water outlet 120 through the check valve 230 and the high pressure switch 240. The reverse osmosis filter element 220 is a prior art, and the filtering process by the reverse osmosis filter element 220 is a technical means well known to those skilled in the art, and the specific principle will not be described in detail.

The opening direction of the check valve 230 is from the reverse osmosis filter element 220 to the water outlet 120, so that the water in the main water pipeline 200 can be prevented from flowing backwards, and meanwhile, the check valve 230 also has a certain pressure maintaining function, so that a certain pressure can be maintained in the water intake pipeline section 201 when water is not taken from the water outlet 120.

The high pressure switch 240 is a pressure switch that changes its operation state according to the magnitude of the pressure value in the pipeline. In this water purifier 100, the high-pressure switch 240 is located in the water intake line section 201 of the main water line 200. The water intake pipe section 201 has one end connected to the check valve 230 and the other end connected to the water outlet 120. The high voltage switch 240 has two operating states, open and closed. When a user takes water from the water outlet 120, the pressure in the water intake pipe segment 201 where the high pressure switch 240 is located is reduced and is lower than the set value of the high pressure switch 240, the high pressure switch 240 is closed, and at the same time, a closing electric signal is emitted. When the user finishes taking water, the pressure in the water taking pipeline section 201 where the high-voltage switch 240 is located rises and reaches the set value of the high-voltage switch 240, the high-voltage switch 240 is turned off, and simultaneously, a turn-off electric signal is sent out.

The water purifier 100 further comprises a water storage pipe 300, one end of which is connected between the high pressure switch 240 and the water outlet 120, and the other end of which is connected to the water tank 310. A suction pump 320 is also included in the storage line 300. The suction pump 320 is used to pump water from the water tank 310.

The water purifier 100 further comprises a controller (not shown) connected to the booster pump 210 and the suction pump 320. The controller may control the pressurizing pump 210 and the pumping pump 320 to simultaneously supply water to the water outlet 120.

Compared with the prior art in which one end of the water storage pipeline 300 is communicated between the reverse osmosis filter element 220 and the one-way valve 230, since one end of the water storage pipeline 300 in the water purifier 100 is communicated between the high-pressure switch 240 and the water outlet 120, the water pumped from the water tank 310 by the water pump 320 does not pass through the one-way valve 230 and the high-pressure switch 240, but directly flows out of the water outlet 120.

Like this, because do not have check valve 230 and the throttle of high-pressure switch 240 on water intaking pipeline section 201, the straight drinking water yield that the user connects and gets at delivery port 120 can increase, compares prior art, connects and gets the same amount of water, and the time will shorten, has improved user's use and has experienced.

Illustratively, the controller is electrically connected to the high voltage switch 240, and the controller activates the booster pump 210 and the suction pump 320 in response to a close signal sent by the high voltage switch 240. In the standby state, high pressure exists in the water intake line segment 201 between the check valve 230 and the water outlet 120, and the high pressure switch 240 is in an off state. The user begins to take water, opening the faucet, and now the outlet 120 is vented to atmosphere, causing the pressure from the one-way valve 230 to the outlet 120 to drop. The high pressure switch 240 measures the pressure drop in the water intake line segment 201. The high voltage switch 240 is switched from an open state to a closed state and transmits a closing electrical signal to the controller. The controller receives an electric signal indicating that the high-voltage switch is closed, and then activates the booster pump 210 and the suction pump 320, so that water is simultaneously supplied from the reverse osmosis filter element 220 and the water tank 310 to the water outlet 120. Therefore, the user can control the starting of the booster pump 210 and the water pump 320 through the mechanical faucet, and the structure is simple and easy to realize.

In one embodiment, the water tank 310 has a liquid level meter (not shown). The liquid level meter is used to detect water level information in the water tank 310 and transmit the water level information to the controller. The controller is used for turning off the water pump 320 when the water level in the water tank 310 is determined to be lower than the lower liquid level limit 311 according to the water level information. The lower liquid level limit 311 is used to determine whether the reaction water tank 310 is empty. When the water tank 310 runs short of water, the suction pump 320 is stopped. The level gauge may comprise a float level gauge, an infrared level switch, or the like.

When a user takes water, the booster pump 210 and the reverse osmosis filter element 220 deliver freshly prepared direct drinking water to the main water line 200, and the suction pump 320 pumps water from the water tank 310 to the main water line 200. If the level meter detects that the water level in the water tank 310 is lower than the lower limit of the water level during the process of taking water by the user, which means that the water tank 310 is in a water shortage state, the controller controls the water pump 320 to stop rotating. While the booster pump 210 may continue to operate, the water received by the user will be made entirely from the reverse osmosis cartridge 220.

Therefore, the water pump 320 is protected, the water level in the water tank 310 is prevented from being too low, the water pump 320 is in an empty state, the service life of the water pump 320 is prolonged, and the product quality is improved. Meanwhile, the energy consumption of the water purifier can be reduced.

When the user closes the faucet to stop taking water, both the booster pump 210 and the suction pump 320 are still in operation. The water pump 320 is typically a brushless pump. In this case, the operating pressure of the booster pump 210 is higher than the operating pressure of the suction pump 320, about 20 times or slightly less than 20 times the operating pressure of the suction pump 320. The operating pressure of the high pressure switch 240 is no more than about 10 times the operating pressure of the suction pump 320. When the faucet is closed, the main water line 200 is connected to the reservoir line 300, and the water intake line 201 is blocked. Even if both pumps are operated, water flows from the main water line 200 to the water tank 310, i.e., water is stored in the water tank 310. When the water tank 310 is full of water, the pressure behind the check valve 230 can be built up, and the high-pressure switch 240 can be turned off when the working pressure of the high-pressure switch 240 is reached. The controller receives the electric signal that the high voltage switch 240 is turned off, and then controls the booster pump 210 and the suction pump 320 to stop working.

Illustratively, the level gauge of the water tank 310 is also capable of detecting whether the water level within the water tank 310 is above an upper level limit 312. The upper liquid level limit 312 is used to determine whether the reaction water tank 310 is full. Alternatively, the liquid level meters may include an upper limit liquid level meter and a lower limit liquid level meter, which detect whether the water tank 310 is full of water and short of water, respectively. Of course, the above function can be realized by one liquid level meter, that is, whether the water tank 310 is full of water or lack of water can be detected by only one liquid level meter. Thus, when the user stops taking water when the faucet is closed, the controller may control the booster pump 210 and the suction pump 320 to stop operating when the full water signal is received after the water tank 310 is full of water and if the high-pressure switch 240 is not turned off yet.

In this way, the water stored in the water tank 310 can be prevented from overflowing to affect the use experience of the user.

Illustratively, the reservoir line 300 may also include a reservoir solenoid valve 330. The water inlet of the water storage solenoid valve 330 is connected to the water tank 310, and the water outlet of the water storage solenoid valve 330 is connected to the main water line. The controller is electrically connected to the water storage solenoid valve 330. The controller is used for controlling the water storage electromagnetic valve 330 to be powered on when the water level in the water tank 310 is determined to be lower than the upper limit of the liquid level according to the water level information; and the controller is used for controlling the water storage solenoid valve 330 to lose power when the water level in the water tank 310 is determined to be higher than the upper limit of the liquid level according to the water level information. The water storage solenoid valve 330 may be of the same type as the water inlet solenoid valve commonly used in water purifiers. The water storage solenoid valve 330 has a water inlet and a water outlet.

The water storage solenoid valve 330 has a unidirectional conduction mode and a bidirectional conduction mode. The water storage solenoid valve 330 is in a bidirectional conduction mode when powered on and in a unidirectional conduction mode when powered off. In the two-way conduction mode, water may flow from the water inlet toward the water outlet of the water storage solenoid valve 330, or from the water outlet toward the water inlet of the water storage solenoid valve 330. In the one-way conduction mode, water can only flow from the water inlet to the water outlet of the water storage solenoid valve 330 to draw water from the water tank 310 to the faucet.

As described above, when the user opens the faucet to take water, the high voltage switch 240 transitions from the open state to the closed state and transmits a closing electrical signal to the controller. After the controller receives the electric signal that the high-voltage switch is closed, the booster pump 210 and the water pump 320 are started. The water level in the water tank 310 drops below the upper level limit 312. The water storage solenoid valve 330 is in the two-way conduction mode. However, when the faucet is opened, the pressure at the faucet is lower than the pressure generated by the booster pump 210 and the pressure generated by the water pump 320, so that both the direct drinking water newly prepared by the reverse osmosis filter element 220 and the water pumped by the water pump 320 from the water tank 310 flow to the faucet.

When the user closes the faucet to stop getting water, the water storage solenoid valve 330 remains in the two-way conduction mode due to the water in the water tank 310 being not full. The booster pump 210 and the suction pump 320 continue to operate. However, since the operation pressure of the booster pump 210 is higher than that of the suction pump 320 (which will be described in detail later), the water flow in the water storage line 300 is directed from the main water line 200 to the water tank 310. At this point water purifier 100 is in a stage of storing water into tank 310.

Illustratively, the booster pump 210 has a first operating pressure, the high pressure switch 240 has a second operating pressure, and the suction pump 320 has a third operating pressure. Since the booster pump 210 functions to pump the raw water into the reverse osmosis filter 220, it generally has a higher pressure. The high-voltage switch 240 is used for detecting the pressure in the water path, and once the pressure exceeds a preset value, the high-voltage switch is turned off, and sends a turn-off signal to the controller, so that the water purifier enters a preset program. The suction pump 320 functions to pump the water in the water tank 310 out at a low pressure. When the booster pump 210, the high-pressure switch 240 and the water pump 320 are selected, it is satisfied that the first working pressure is greater than the second working pressure, and the second working pressure is greater than the third working pressure. On the one hand, the pressure value required by normal work of each component is obtained, and on the other hand, the setting is carried out, so that the program of the water purifier is relatively simple, and the water purifier is convenient to use and maintain. Illustratively, the first operating pressure of the booster pump 210 may be around 1 MPa. The second operating pressure of the high voltage switch 240 may be about 0.3 MPa. The third working pressure of the water pump 320 may be about 0.05 MPa.

When the water in the water tank 310 rises to the upper level limit 312, the water in the water tank 310 is at a full water level, and the water storage solenoid valve 330 is in a one-way conduction mode. The reverse osmosis filter element 220 continues to produce water, and the freshly produced direct drinking water flows to the main water pipeline 200. Thus, a high voltage is generated in the main water line 200 sufficient to open the high voltage switch 240. After the high-voltage switch 240 is turned off, the controller receives an off electrical signal sent by the high-voltage switch 240, controls the booster pump 210 and the water pump 320 to stop working, and enables the water purifier to enter a standby state.

Illustratively, the suction pump 320 is located between the water storage solenoid valve 330 and the water tank 310. In general, the water suction port of the water pump 320 is larger than the drift diameter of the water outlet, which is to ensure that the water suction path of the water pump 320 is smooth and the normal working efficiency of the water pump 320 is ensured. The water storage solenoid valve 330 is disposed downstream of the water pump 320, so as to avoid the water storage solenoid valve 330 forming resistance at the water suction port of the water pump 320 and affecting the normal operation of the water pump 320.

Illustratively, the suction pump 320 comprises a brushless pump, which is generally composed of a dc motor and an impeller, and has a small size, a wide application range, and a standardized and low cost.

Illustratively, the water purifier 100 also includes a water inlet solenoid valve 250 located on the main water line 200 before the booster pump 210. The water inlet solenoid valve 250 is connected to the controller. The water inlet solenoid valve 250 may have only two on/off states, and the operation state of the water inlet solenoid valve 250 may be linked with the booster pump 210, that is, the booster pump 210 and the water inlet solenoid valve 250 are simultaneously turned on and off. The water inlet electromagnetic valve 250 opens water inlet when water is produced or washed, and closes water inlet when standby or power failure, so that the waste water is prevented from flowing for a long time, and the purpose of not wasting water when the water purifier does not work is achieved.

Illustratively, the water outlet 120 includes a line machine interface 121 and/or the faucet interface 122. In daily life, in order to heat or freeze the direct drinking water produced by the water purifier 100, a pipeline machine is connected to the water outlet 120 of the water purifier 100. The difference lies in that the user operates the solenoid valve in the pipeline machine mostly, but the operation process and principle are the same as those of the mechanical faucet, and reference may be made to the above description, and details are not repeated here.

Thus, the water outlet 120 of the water purifier 100 can be communicated with various devices or apparatuses, so that the applicability is high, and various choices can be provided for users.

Illustratively, the water purifier further includes a pre-filter 260 disposed before the booster pump 210 and/or a post-filter 270 disposed on the main water line 200 after the water storage line 300. Leading filter core 260 is the first coarse filtration equipment to the purifier, can get rid of visible solid matter impurity in the pipeline, mainly has rust, silt, alga, colloid etc. and plays positive guard action to floor heating pipe, domestic tap, electrical apparatus etc.. The rear filter element 270 is arranged at the downstream of the reverse osmosis filter device, and the main function of the rear filter element is to improve the taste, and the active carbon in the rear filter element 270 can absorb peculiar smell, so that the water becomes sweet and delicious, and the use experience of a user is improved.
